The Best Light Box for Watercolor Paper

The light box has found favor in several industrial applications from fashion and design to photography and even therapy for specific disorders. However, if you are reading this, you are probably interested in an artist light box. What is a light box? A light box also known as a light board is a special electric pad-like device that generates light. It uses the new light-emitting diodes (LED) technology to radiate light of a standard wavelength. The artist-grade light box offers a drawing pad with even backlight, which improves your view, especially in poorly lit environments. By placing your drawing paper on top, you have better clarity regardless of the surrounding light conditions. A light box is also integral for tracing designs and illustrations on nontransparent paper eliminating the need for carbon paper. It illuminates even the finest of details to ensure the artist stays within the course. The best thing about it is that it is a versatile device for various art and craft projects. But not all are created equal. If you intend to use a light box with watercolor paper, you need a device that is up to the task. Watercolor paper is typically a thick sheet and requires ample brightness compared to standard sketching paper. So what is the best light box for watercolor paper? The best light box has a strong enough light (high lux) to shine through thick watercolor paper. The size of the lighted surface should also be large enough to fit your standard watercolor paper size. Finding a light box for your specific needs can be a daunting task given the huge variety available in the market, but your search ends here. In this article, you will find a selection of the best light box for watercolor paper. We also highlight a few factors to consider before purchasing one. Light Boxes For Watercolor Paper - What to Look For Having a hard time choosing a light box for watercolor paper? Do not be in a hurry. It is essential to analyze your requirements as a watercolorist against the features before purchasing one. Here are great pointers that can be a starting point for your search. The intensity of luminous light (lux) produced by the light box is essential when selecting one. A suitable model should be strong enough to penetrate through watercolor paper. Watercolor paper is usually heavy, ranging from 90-300 lbs, meaning it is quite thick. Your light box must be strong enough to shine through this heavy paper and other artist quality papers. It is also great if the brightness level is adjustable to suit specific lighting needs and materials, particularly if you are an artist who works with a variety of media. The weight, thickness, and screen dimensions are an essential aspect of a light box. The size affects portability as well as the lighted picture size. A2 will accommodate most common paper sizes but A4 is the most common for hobbyists. Size decreases as the number increases, so decide accordingly. A light box will either need a USB cable or an AC/DC adapter to source for power. A few models are battery-powered but their intensity is not powerful enough for watercolor paper. AC/DC powered units are the brightest and most consistent. USB and rechargeable models are highly portable and usable even when you do not have access to an electric outlet. For top-notch quality light boxes, and most artist's materials, it's usually a good idea to be wary of generic products, as many are manufactured using substandard components. Now that you have some ideal features in mind, let's look at some of the top 5 light boxes for watercolor paper: An artist's tools are their everything. You wo not want to make this decision lightly. Read on for more information about each so you can pick the best lightbox for your masterpieces to come. One of the highest quality light boxes you can get your hands on is this bad boy from Tiktecklab. The A4 sized pad weighs just 1.45 lbs and less than 1/4-inch thick; you just can not go lighter or slimmer than that. But do not let its dimensions fool you into dismissing its capabilities. The LED light has a brilliant brightness sufficient enough to illuminate through watercolor paper. However, you can also dim it in the settings should you ever need to. The Tiktecklab Light Box is a USB powered device usable with a phone laptop or USB adapter plug. Couple that with its feather-weight, and you have a highly portable tool. You can quickly turn it on/off with a touch sensor switch by tapping it or grazing it to adjust brightness. There is an on-screen ruler/scale in case you need to use one. There are also four anti-skidding rubber pads at the bottom four corners if you do not want to scratch your beautiful surfaces. It is a smart portable and affordable choice for artists with subtle but thoughtful nuances that make it the best light box for watercolor paper. The new and improved Artograph light tracer is a tough one. It not only delivers above and beyond expectations but will also stay with you for the longest time. It has a sturdy yet lightweight ABS plastic build that can withstand everyday wear and tear from heavy use. The slightly wedged body positions the screen at an angle for a comfortable view without straining the neck or back. It utilizes a six-foot power cord that ensures a consistent soft diffuse white LED light without flickering, unlike earlier versions that had changeable fluorescent bulbs. Can it handle the thickness of watercolor paper? Absolutely. The Tracer produces up to 14000 lux of light, which is more than enough intensity even for the thickest watercolor paper. It could be much better if the light were dimmable. Its design also makes it somehow bulky with twice the thickness and weight of other models. Still, you get two accommodating size options: 10 x 12 and 12 x 18. Each has an onboard slot and a secure in-built storage tray for those small art tools. Artograph is made in the US so you can only expect the best craftsmanship and quality assurance. The price is a true reflection of what you will get. Totally worth it for an accessory that will serve you for many years. If you are looking for something aesthetically pleasing, this light box from Litenergy is the deal. It has a sleek design with acrylic panels and comes in four color variants; candy pink, neon green, silver, and black. Measuring just 5mm (0.2inches) thick and weighing 1.5lbs, it is slim and ultralight too; you wo not wear out your hands. Performance-wise, the light box can hold up to a variety of tasks. Thanks to its 4000 lux brilliant LED light, you wo not have issues even with thick sheets like watercolor paper. It is flicker-free with eye protection technology. You can work long hours without excessively straining or damaging your sight. You are able to adjust the brightness to your taste by simply long pressing the touch start button. The device has a good memory and does not reset brightness when you turn it off. In the box is a USB cable that you can plug in any device or USB adapter to power the device. Once it clicks in, it stays steady. You can easily find the cord in local stores and replace it if worn out or lost. For the price, it is a solid light box that the casual artist and hobbyists who want the convenience of drawing and painting occasionally anywhere will love to have. Huion is a fairly new player in the market, and their electric hand-held writing devices come with the latest technology. This acrylic construction light box, for instance, is sturdy and beautiful. Its most terrific selling point perhaps is the large working surface measuring 16.9 x 12.2. There's plenty of room for a variety of paper sizes. Despite the oversized screen, you wo not believe how thin and light it is. It weighs only 3.75 lbs and is 0.3 inches (7.62mm) thick. It's a comfortable size to use on your lap without fatigue. The screen has an onboard scale in case you need it. The rapid response one-touch switches it on/off. Stepless brightness adjustment is just a long press away on the same button. The highest setting goes upto a super bright 4050 lux, surpassing other models from the same family (Huion) and making it an ideal light box for watercolor paper. It comes with a 12V US power adapter that does not overheat the device despite long working hours. So you can work on bulky projects with the same consistency without worrying about damaging the system. Skimming through hundreds of brands for a great light box is burdensome, but getting a good one under 20 dollars is almost virtually impossible. The Comzler goes against all the odds to offer the most affordable light board while maintaining acceptable quality standards. What does it have to offer for the price? Well the 9 x 13 screen is lit evenly with three adjustable intensity settings. You can switch between them with an easy-to-use touch-sense button that also turns the device on and off. The LED light has a low, medium, and high intensity mode. The highest setting is so bright it will illuminate even a 140 lbs watercolor paper. You might struggle with intricate details if using 300 lbs. Unlike the rest of the products in this review, it allows users to attach the paper using magnets onto the surface to pin it accurately in position. This is especially helpful for kids -you know they can not keep still and steady. It is also ultra- thin, measuring 0.2 inches wide and lightweight, too, so young hands can handle it without any problems. A USB cable that comes with the device needs to be connected to a power supply to turn it on. This is a highly giftable, low budget light box ideal for young artists, beginner artists, or anyone looking to hone their artistic skills. How to Transfer Drawings Onto Watercolor Paper With a Light Box Using a light box is simple. You will place your reference image on the lit light board and then secure the watercolor paper on top of them, either using magnets for magnetic lightboards or adhesive tape. You can now trace the image. It's best to use a very light pencil so that the outlines do not show once you actually get to coloring. Expert level artists can skip the pencil and color directly, depending on their medium. 140 lbs watercolor paper (which is the most popular) or anything lighter will work just fine with any one of the above light box recommendations for watercolor paper. Anything heavier, and it will be a little hard to trace the less bold lines. Up Next: The 5 Best Watercolor Crayons

2. How long 12V car battery would last for 12V LED light?

led's dont draw alot of current as opposed to normal bulbs, but the size of the battery and the number of led's will make the runtime vary. you can always charge it back up by hooking it to a car wiith jumpers or using some other 12v battery charger. If house plugs are totally out of the question for whatever reason, then either go with multiple batteries to extend the running time (as long as you've figured out how your going to recharge them) or look into getting a small gas generator maybe.

Cubbon Park to Get 800 Smart Led Lights with Motion ...
BENGALURU: Soon the lights in Cubbon Park will automatically brighten or dim based on the movement of people in the park, the time of the day and the season, thanks to the over 800 smart LED lights fitted with motion sensors and environmental sensors currently being installed there. The lights, which can be monitored from a centralised control system, are programmable according to seasonal variations. The motion sensors will also enable the lights to stay dim when there is no movement of people inside the park, said officials of Bangalore Electricity Supply Company (Bescom), which is executing the smart lighting project in Cubbon Park. On the other hand, the environmental sensors will help the lights dim during long summer days. They will brighten earlier in the evening during rainy and winter season when the days are shorter, they added. "We will install smart display screens and integrate them with the environmental sensors, which will help display pollution levels. The screens will also provide details of various events at Cubbon Park and explain the heritage of the park, besides spreading awareness about the dos and don'ts while inside the park. Free Wi-Fi will also be provided to visitors as part of the project," said Anil Kumar D'Souza, DGM, Technology Innovation Centre, Bescom. "Two of the proposed 50 LED screens have been installed at Cubbon Park on an experimental basis. The rest will be installed in the coming week. The communication system will be tested next month, said Bescom officials.

Blue LED Light in Honda Civic?
Honda Civic Led Lights1. Is there a fundamental difference between an LED and a light bulb?A common light bulb uses electric current to heat a filament to incandescence - most of the energy is waisted as heat energy and very little is given off as light. Typically, they are 3 or 4 percent efficient at producing visible light. A LED, on the other hand, is a solid state device witch emits light in a narrow spectrum from the p-n junction of the diode. It is far more efficient with a lot less wasted energy in the form of heat.2. Can I use an LED as a light sensor? I got this circuit, http://electronicsforu.com/electronics-projects/led-light-sensor, it was not working practically.no only led can not be used as light sensor........ to sense light we use LDR (light dependent resistor ) .nA Light Dependent Resistor (LDR) or a photo resistor is a device whose resistivity is a function of the incident electromagnetic radiation(visible light). Hence, they are light sensitive devices. n LDR working and principle follow link :nLight Dependent Resistor | LDR & Working Principle of LDRCan led be used as light sensor?3. Best Camping Lanterns for Trekking & Adventure - Expert ReviewsModern lanterns are a far cry from the unsafe gas varieties often found hanging in tents of expeditions past. Usually powered these days by LEDs, these lanterns provide a great semi-permanent light source for inside and out, whether you are off on a weekend jaunt, at a festival, or setting up basecamp on a more extreme adventure. We've picked a few of our favourites camping lanterns, and as always, tried to find a balance between great quality, and great value. The UCO is one option that does not use LEDs, making it a lovely night time light, for reading, relaxing, and really getting into the camping spirit. It's essentially a collapsible candle holder, which holds UCO's own specially designed candles perfectly. Up to 9 hours of burn time per UCO candle. Build quality Choose from either aluminium or brass construction on the UCO, both are hardened and super hard-wearing. Anything collapsible needs to be durable, and the UCO is sure to stand up to repeated use. Folds away into a neat foam capsule for easy transportation. Materials The UCO is made from either brass, or anodized aluminium. Both are great for use inside and outside. Features There are lots of things we love about the UCO, not least is the fact that it allows you to use real candles rather than LEDs. It has the added benefit of warming your tent, and it helps to remove condensation. The Goal Zero Mini is the little brother of the bigger Goal Zero Lighthouse, although it still packs a massive punch at 210 lumen. It fits in the palm of your hand, and the legs fold in completely, making it even more portable and convenient. The Lighthouse also doubles as a charging station, and features a USB port for plugging in phones and tablets. Build quality The Lighthouse is a great piece of kit, made from a combination of lightweight plastics and steel legs. It's light and sturdy, and as long as it does not get beaten around too much, it will last. One of our favourite camping lanterns. Materials The slim steel legs are foldable and surprisingly strong. The rest of the Lighthouse is made from quality plastics, making it lightweight and portable. Features As well as being a solid lantern, the Lighthouse doubles as a charging station. Use the built-in USB port to charge phones, Kindles and tablets, and never run out of juice when you need it most. Use your phone to turn the Princeton off and on, and enjoy 250 lumen of pure, evenly spread LED light. The Princeton is collapsible and light, and the sturdy legs fold underneath, making it even easier to pack and transport. The stackable upper portion is an attractive feature, too, and we love the Princeton as a gift option for regular overnight hikers and campers. Build quality Quality can be a difficult thing to find in collapsible, portable camping lantern, but the Princeton is both extremely well made and conveniently small. We've got no complaints at all about the quality of the stackable upper, or the folding legs, and the Bluetooth control seems to work well, too. Materials Made mostly from durable plastics, the Princeton is light and rainproof, another plus for extreme outdoor enthusiasts. One of the best camping lanterns on the market today. Features It looks a little strange at first with its crumpled upper segment, but the Princeton is made to perform, and stacks easily and quickly. The Bluetooth control is a bit of a novelty, but if you are in bed and do not feel like getting up to turn off the lantern, then having the option to turn it off remotely is a thoughtful touch. The Apollo is a simple, thoughtfully built LED lantern that's light on extra features, but superb at what it's made for. 80 lumen of light housed inside a frosted globe, the Apollo distributes its light evenly and efficiently. The dual reflector inside the globe is responsible for distributing the light evenly, and it works nicely inside a tent, or as an ambient outdoor light. Build quality Because the Apollo is low on extras, there's a big focus on quality. It's made from plastic and a frosted plastic globe upper, and the legs are steel. You can either stand the Apollo on its tripod legs, or use the steel hanging handle to hang it from branches or inside your tent. Materials Made mostly from plastic and stainless steel, the Apollo is a trusty outdoor companion, that's lightweight, durable and weatherproof. Features There's not a lot extra to say about the Apollo. It's a simple, powerful LED lantern. It does feature folding legs, and the dual reflector system inside the frosted globe helps to distribute the light evenly, indoors and outdoors. For the price, this is one of the best collapsible lanterns we've seen. The TaoTronics makes a fantastic addition to your weekend camping kit, and is also great as an ultra-lightweight fishing light. The lantern collapses down to the size of a beer can, and when unfolded, features a hanging handle so you can position it wherever you like, away from the wet ground. Build quality The TaoTronics does not have the same quality feel as some of the other higher-end lanterns on our list, but for the price, it's decent enough, and it's good to have one stashed away in your kit for emergencies. Materials Keeping costs low, the TaoTronics is made from reasonable-quality plastic. It's not incredible, but it does the job. One of the most cost effective camping lanterns on the market today. Features Folds down into itself, to around the size of a beer can. The TaoTronics is an LED lantern, so it shines brightly without any noticeable dip in brightness until the batteries are near empty. LEDs tend to perform well in extreme conditions, too, so this a good one to have as a lightweight backup on your travels.

Where Can I Buy a Fake Car Alarm Light From? Or Where Can I but a Smal Colored Led Light to Use As a
just get one of those bounce balls with the light and cut it out and than use that1. Ceiling LED light emits very dim light when switch is off! [closed]There are two typical reasons for this:The Phosphorous used in the led is experiencing chemiluminescence, a cold chemical reaction that produces light. The Phosphor is normally used to be give leds their white color through photo luminescent reaction, reacting to photons of a different wavelength, but it can glow in the dark without that.The light bulb is on a circuit with a switched neutral wire, instead of a switched hot wire. This means that the AC voltage on the hot wire can still slightly power the leds and/or the capacitors in the light bulb, leading to a few milli or micro amps of current to flow through ultra efficient leds, lighting them up.You could test this by putting the bulb in a switched lamp with a non-polarized power connector plugged in one way, and then flip the connector around the other way. One way should result in completely off leds.2. i have a bmw 3281 2013 and i wana get the angle eyes and led light but i know nothing about them?if you dont have them stock, meaning installed from factory, you can have some indy shop installed it for you, or you can wait til aftermarket headlight came out. since the car is still kinda new. it is pretty pricy at this point. i found one shop quoted 700 dollars to have them installed3. Can I use a standard American LED light bulb in a 220v lamp?No you can not . American electrical devices are designed to operate on 110 V, ac, 60 Hz. So connecting the American LEd lamps to a 220 V source will instantly blow it up4. Can you move a solar sail with a led light?Theoretically any light source would do it, but practically probably not, since you would have to be out in space away from any significant gravitational pull to try it5. Will a 9watt LED light cure gel polish?? If so, how long does it take?should not it be ultraviolet lamp?6. How can I build a led light that will run off of standard 110 house current?Relatively easy. You will need the specs on the LED's you plan on using. They have voltage and current limits which are unforgiving. Exceed a limit and the LED burns out like a fuse. A LED is simply a diode, a rectifier which happens to give off light when it is forward biased and is conducting current. Your problem is one of voltage and current. Too much of either and teh diode burns out like a fuse. A typical LED forward biases at something over 0.5 volts, and can usually tolerate about 10-30 milliamperes (MA) of current. If we These are rated in milliwatts (MW) of heat dissapation. A typical LED (the kind which is about 0.2 inch diameter and about 0.3 inch long) can dissapate about 10 MW, which means I have to adjust current and voltage according to Ohm's Law, E=IR, voltage equals curent times resistence, and P=IE, power equals current times voltage. 10 MW means I can have 10 MA and 1 volt across the diode, 5 MA and 2 V, or any combination which does not exceed any of the rated limits. So, how do you get this? Use a stepdown transformer as working with the power line directly is VERY VERY DANGEROUS. Any wall wart style will do. Radio Shack and several other electronics stores will have these at a reasonable cost. Look for one with about a 6 volt DC output. With the example of the 1 volt drop and 10 MA current, you should be able to connect 6 of these in series (anode to cathode, anode to cathode, just like batteries in series) and connect them directly across the 6 VDC supply and they all should light. If it is not bright enough (as I am being quite conservative in my estimates), you might be able to remove one LED from the string to up the current (light output) without exceeding the current limits. Use a meter capable of measuring MA to monitor the current drawn by the string. By using a transformer to lower the voltage you use as a power source, this means you can parallel a rechargeable battery downstream of the transformer to supply power to keep the LED's lit when the power line fails. This is how a lot of emergency lights in buildings work these days. The low voatage power supply lights the lights and keeps the battery charged and if the power line fails, the battery keeps the lights lit. You will need to do more research on how to add the backup battery since there is not room here to give much in the way of detail here to charge the battery and keep it in good health (overcharging is the cause of early failure of standby batteries). Using a combination of strings in series and parallel up to the current capacity of the power supply will determine your end result. I am only giving a basic outline here since I am not legally going to allow myself to be obligated in the event you do something stupid which gets you killed working with the power line drectly. Again I say, DO NOT WORK WITH THE POWER LINE DIRECTLY! ALWAYS use a stepdown transformer to protect yourself from becoming a crispy critter and NEVER assume a circuit is dead until you verify it is really deenergized. You can DIE and there is no coming back from death as we know it

The Best CRI for Your Office Lighting
The Best CRI for Your Office Lighting
The Best CRI for Your Office Lighting Proper lighting plays an important role in the aesthetic and ambiance of an indoor space. For businesses and commercial facilities it is crucial to give attention to the layouts for lighting. Plentiful, uniform lighting improves visibility and reduces eye strain for office workers, in particular. As such, a well-lit office may improve overall productivity. Businesses are increasingly adopting Light Emitting Diode (LED) lights to provide affordable, high-quality lighting in their office space. LED lights consume less electricity than traditional light sources such as incandescent bulbs and fluorescent tubes. LiTian Lighting offers a diverse line of LED lighting and fixtures for indoor office use. We are one of the top commercial lighting manufacturers and suppliers in the U.S. and it's because of our commitment to excellence that we provide products that are efficient, durable, and register well on what is known as the Color Rendering Index (CRI). What is the Color Rendering Index? Consider the direct impact lighting can have on employees. While subjective assessments of light quality are important, an objective measure helps decision makers select an optimal lighting solution for their application and environment. The Color Rendering Index (CRI) offers a way to quantify the quality of light. The CRI uses eight pastel colors to determine how a solid-state light source renders color. The CRI operates on the following principle: If a light source renders the eight standard pastel colors well, it will also render all colors well. A light source's CRI ranges from 0-100. This number indicates how well a specific light source shows colors in comparison to a standard light. For example, most natural daylight has a CRI of about 75. The scale works as follows: The closer the CRI is to 100, the better the light source is at accurately rendering colors. A CRI value from 90-100 is considered excellent. CRI values less than 55 are poor at color rendering. LED lights generally have a CRI of 80-90, which means their light output is very similar to or more optimal than natural daylight. Colors lit by LED lights are almost identical to their color in natural sunlight. At the same time, LED lights can be brighter than natural light and are more cost-effective than conventional light bulbs. Conventional light sources such as fluorescent tubes can render colors very differently than natural light, making them appear artificial and causing undue strain on the human eye. In addition to color quality, LED lights have a much longer service life than incandescent bulbs or fluorescents. LED lights are an optimal light source for achieving good-to-excellent CRI for your business while keeping expenses low. Where on the CRI Scale is Office Lighting? Businesses should strive to make their office lighting as close to natural light as possible. Doing so will improve employee wellness, morale, and productivity. Dim or poor quality lighting not only contributes to physical strain, but can have a greater impact on accomplishing tasks that are tied into your business goals. Simply put: the environment you create is the setting for success. Research supports these claims. For example, hospital lighting has a direct impact on the performance of nurses. Another study showed that improving the lighting in post offices tremendously improved the productivity of postal workers. Daylight has a CRI of around 75, which means businesses should aim to achieve a CRI of 75 or better in their offices. Since LED lights have a CRI of about 85, they provide an optimal choice for commercial office lighting. As they cost less per year of service due to their long life and low power consumption, LED lights also offer additional long-term cost savings. LiTian Lighting is a leader in retrofitting conventional lighting systems with LEDs, helping businesses to improve employee productivity while reducing lighting expenses.1. LEDs for General Lighting: What They Offe - Maxim IntegratedThis tutorial discusses the expanding role that light-emitting diodes (LEDs) are playing in general lighting applications. It compares LED performance versus other lighting technologies. It also analyzes the main challenges of designing LED lamps that retrofit existing lighting systems. Light-emitting diodes (LEDs) are a rapidly evolving technology and are becoming viable for many general lighting applications, usually referred to as solid-state lighting (SSL). The most relevant examples of LED lighting applications are indoor uses in commercial, industrial, and residential environments; outdoor applications like street lights and parking lights; and architectural and decorative lighting where LEDs were initially adopted because of their ability to emit the whole spectrum of colors. LEDs have been an effective solution for architectural lighting for some time. Today LEDs are penetrating the mainstream general lighting market, thanks to their higher performance compared to other lighting technologies: In summary, LEDs offer many advantages over incandescent, halogen, and fluorescent lamps. Consequently, designers continue to find more applications for LED lighting, but that discussion could consume us for a long while. This review will focus on only two, but quite timely, applications: LED retrofit lamps and remote-controlled LED lighting. LED retrofit lamps are made to replace incandescent, halogen, or fluorescent lamps in the same socket. These LED lamps must fit in the existing form factor and be compatible with the existing infrastructure. LEDs for remote-controlled lighting allow greater flexibility in dimming and changing the color of the light. LED lamps are inherently digital systems, making it straight forward to integrate communications for lighting automation. The use of wireless or powerline-communication (PLC) remote control reduces power consumption, lowers operation and maintenance costs, and enables new LED applications. Many would argue that the LED retrofit lamp market is the fastest growing application for LED lighting today. The reason for this fast growth is actually quite straightforward: these lamps do not require a new electrical infrastructure (i.e., cabling, transformers, dimmers, and sockets), a significant advantage for LED technology. Fitting an LED lamp into the existing infrastructure challenges the designer in two principal ways: We shall discuss each challenge in turn. While size is important for a retrofit, thermal limitation is often more critical. LEDs emit only visible light; they do not irradiate energy at infrared wavelengths like other technologies. Thus, while LEDs are more energy efficient than incandescent or halogen lamps, they dissipate much more heat through thermal conduction in the lamp. Thermal dissipation is also the main limiting factor for the amount of light that a lamp can produce. Today's LED technology in retrofit lamps can barely achieve a level of brightness that is acceptable for the mainstream market. Pushing the limits of brightness and, consequently, thermal design are essential for designing a commercially successful product. A corollary issue to the thermal dissipation is the lifetime of the driver board. To emit more light, the lamp must work at a fairly high temperature (80C to 100C). At these temperatures, the lifetime of the driver board can limit the operation of the whole lamp. Electrolytic capacitors are the biggest challenge since they are the first component that fails at high temperature. Maxim's driver solutions for 120V AC/230V AC and 12V AC give customers the option of not having electrolytic capacitors, if they can accept higher LED ripple current. If instead the customer decides to use electrolytic capacitors, Maxim driver solutions are fault tolerant: a deterioration of the electrolytic capacitors causes the LED ripple current to increase, but the lamp does not fail. Retrofit LED lamps must work correctly in infrastructures that include cut-angle (triac or trailing-edge) dimmers and electronic transformers. Working off the 120V AC/230V AC line, the lamp can be preceded by a triac dimmer. Triac dimmers are designed to work well with incandescent and halogen lamps, which are perfectly resistive loads. With LED retrofit lamps, however, the LED driver is generally a very nonlinear and not purely resistive load; its input bridge rectifier typically draws brief, high-intensity peaks of current when the AC input voltage is at its positive and negative peaks. This LED behavior does not allow the triac dimmer to work properly, because it provides neither the needed start current nor the hold current. As a result, the dimmer does not start properly or turns off while operating, and the LED lamp flickers. The electrical infrastructure is even more complicated for 12V AC input lamps, because an electronic transformer and trailing-edge dimmer can be connected at the lamp's input. Again, a 12V AC input lamp driver that uses the traditional bridge rectifier and DC-DC converter topology flickers because of incompatibility with the transformer and dimmer. Maxim's LED solutions for 120V AC/230V AC and 12V AC input lamps use a single-stage conversion. By shaping the input current so that the light does not flicker even when dimmed, these solutions are compatible with triac and trailing-edge dimmers and electronic transformers. No other solutions for MR16 lights offer this feature; few solutions for PAR, R, and A lamps offer it. In addition, these solutions provide better than 0.9 power-factor correction and require a very limited number of external components. The 120V AC/230V AC input solution uses the MAX16841 , while the 12V AC solution employs the MAX16840. Both parts are available for evaluation and use in mass production.2. How to supply 12 volt DC to all the windows in a new house buildYou just answered your own question, "how do I splice 30 connections" / "breaker box for DC". However only one breaker box/service panel/load center on the market is capable of supporting DC, and that is Square D's "QO" type (the one with the 3/4" breakers; NOT the cheapie Homeline!)The trick is voltage drop. The much lower voltage is also much more sensitive to resistance loss through the wires. That forces you into larger wires. The good news is, economics of scale make #12 or #14 wire intended for AC mains barely more expensive than the #18 or #22 one normally associates with low voltage DC. There's no substitute for figuring out your current draws and doing the load calculations based on your distance. This must be done.Note that 24-volt systems are 4 times better for voltage drop. Crunch the numbers and you will see. If it's feasible to go 24V, consider it.12V or 24V DC systems can be an incredibly verstaile addition to a home, and can even allow it to weather long power outages with high functionality, much moreso if the house is smartly designed around that idea.For instance, a variety of LED lighting is made for 12/24V, including the popular LED strips, which dim very effectively, and even permit RGB color. Motion sensors are cheaper in 12/24V. If you make this auxiliary lighting, you could have it during power outages by adding a battery to the system. Many Internet modems/routers work on 12V, as do many TVs, and a typical Roku box or other smart-box attachment will also like 12V power. So there you are watching Netflix in the power outage. 12/24V house-sized refrigerators are not worth buying, but you can run an inverter for the times the fridge needs to run.The batteries need to be sized for the run-time you want to have, but them with some solar panels to top them up can be a lot cheaper than an installed generator system with changeover switch, yadayada. Heck a modest battery system is cheaper than those hokey 10-circuit switches alone. Or very small generator can be used simply to top up the batteries during period of low sun (or for that matter, your car's alternator).It could build out into quite a system if you wanted to3. Is there a LED lighting product that can replace coventional interior overhead lighting?Yes, there are a few on the market. Currently they are more comon and accessable in CA but you should be able to go online and find / purchase them. The upfront cost may be alittle steep but it will pay off in the long run

How to Fix Dc 12 Led Lights That Burn Out Due to Excess Voltage Or Current
How to Fix Dc 12 Led Lights That Burn Out Due to Excess Voltage Or Current
Unfortunately you do not tell us how much current is needed by your LEDs and fans.Assuming that this current is less than 2 A you could consider using a buck-boost converter like this:In the description this model is listed as usable up to 3 A but you have to take that with a grain of salt. I would use it up to 1 A and not be worried. Maybe it would survive 2 A just fine, At 3 A it might get too hot and not work in the long run. Then it would be better to use a module rated for 5 A.Actually the name is wrong as the converter first boosts the voltage up to for example 24 V and then uses a DCDC down converter (a buck converter) to lower the voltage to the voltage you need, for example 12 V.This means the module will output 12 V as long as the input voltage stays within (quite broad) limits. So even at 10. 5 V or 15 V at the input, you will always get 12 V at the output.There are many different modules similar to this one, just search for "Buck boost module"1. What do I need to buy for my car to make LED lights flash to music?You need a modified color organ circuit, basically band pass filter, level detector, and comparator2. If i buy a custom xbox 360 controller can i change the led lights from the default green to purple?You can. You have to either put them in yourself, or get them like that. As for the battery drainage, if you are just getting it in the circle around the "X" then no. If it does, it will drain it so slightly, you wo not even notice a difference. Just make sure you use eco ones.3. In New York state, is is legal for a motorcycle to have LED lights on while moving?As long as they are not blue or red you can get away with it.4. My Frigidaire GLTF2940FS1 is plugged in but will not start nor will the LED lights come on?check the circuit braker box and make sure it's on. if that's ok, then test the outlet itself with a small appliance5. How do you solve the "half strand out" problem in a strand of LED lights?One of the bulbs in the light strand is defective could be more than one bulb. Find the defective bulbs in the strands and you will have a full working 100 light strand. I've been doing this for the past two weeks hanging my christmas decorations. That was the problem in every strand that did this to me.6. Is it against the law to have blue LED lights on your car in Pennsylvania?Who cares? They are ugly anyways....7. Can I use a 125v toggle switch to hook up led lights to a 12v battery on a motorcycle?12 Volt Toggle Switch8.

No Light on Power Led Light?
No Light on Power Led Light?
If your computer is working fine, probably not. What has most likely happened is that the LED has become unplugged from the mother board1. I'm looking to buy a new TV, would love some insight and some help/ideas from others.?Sorry, but you are not going to find a tv for that price. You might want to look into led's and lcd's rather than 3d. 3d is over rated completely. You wo not find anything for it and it will bump your price up enormously.2. High power LED arrayI am guessing the application you intend is to use UV curing resins by mounting a powerful UV source behind a diffuser lens and LCD screen as a light blocker. The LCD is kept just above the surface of the resin as the tank is filled and the LCD rather than the UV LEDs provides the image resolution. If this is the case, the LEDs can all be the same brightness, which is an advantage because you can use different voltages, 54V for all 15 LEDs in series, 18V for 3 strings of 5 LEDs, 10. 8v for 5 strings of 3. It's a benchtop device so you can get away with things being a bit bulkier, which will make things easier for you. Cooling the LEDs is important, so you may want to look around the usual DIY sources for some massive aluminum heatsink or a bunch of smaller ones depending on how far apart the LEDs are. The MCPCB stars that most power LEDs come mounted to are actually usually adequate for low power, especially with current control, but if you are going to have 15W together in an enclosed space beside an LCD you do not want to heat up, it would not hurt at all to keep it cooler. This will also help avoid a long heat up time while you wait for the LEDs to reach thermal equilibrium and for their brightness to steady. LED efficiency also improves if you keep them cooler.As for a driver, because it's a desktop unit you can get yourself a constant current LED driver of appropriate voltage range for the series/parallel arrangement you decide to use. They are usually about 4-5 inches by 2 inches by 1 inch or smaller depending on power rating. 120 or 240V goes in, constant current comes out to drive the LEDs. If you choose one that's dimmable you will be able to adjust brightness if you want. Here's a link to the section on DigiKey. You can find this sort of thing at numerous websites and sometimes even hardware stores, so you can use this to get an idea what you are looking for. Just fill out columns with things you do know, one at a time, and use "apply filters" in between until you narrow it down. Constant current is usually used with LEDs to eliminate thermal runaway without using series resistors.3. I want to install lights in my guitar. What do I need and what do I need to do to make it work?You will need a lot of LED's which you can buy from a sign shop or electrical wholesaler that are mounted on their own PCB -- you will need some silicone to hold them in place inside-- you will need a good drill bit if you want them to poke out the skin of the guitar-- and you will need the proper size power supply for the number of LEDs you want to use---a junction box for the power supply and some Cable from the power supply to the LEDs--4. Why do my light bulbs glow when off and make noise when on?I suspect you have one (or more) of the following:Many of these work by leaking current through when "off" in order to power themselves, or do other strange things (particularly older dimmers) that are incompatible with many LED and CFL light bulbs.If you have any of the above, switching to a simple switch will do the trick. Alternatively, if you want the "features", look for a switch that requires neutral (of course, that will only work if neutral is available in your switch box). Next best choice would be a switch that specifically claims compatibility with LED and CFL. In addition, an LED bulb that specifically claims "dimmer compatible" will often help as well.If this is already "just a truly ordinary switch", then swapping it for another one (some are less than $ 1) is worth a try.

Motorcycles Turn Signal Come on, but Do Not Flash.?
Motorcycles Turn Signal Come on, but Do Not Flash.?
The blinker can works by sensing current. The old incandescent bulbs draw a bit of current, as they are rated at around 21 watts each. That's about 4 amps in a 12 volt system. I would be looking for a blinker can that is designed to work with led lights, as they draw heaps less current than the old bulbs.1. im gonna invest in a stock i want a stock that grows rapidly with high risk any suggestions?My favorite speculative stock is Sunovia Energy Technologies, Inc. , ticker symbol (sunv) or (sunv.ob) if looking on yahoo. The company makes LED lights, Solar Panels, and is Partnered with a company that makes infrared products. The company just hired 2 Dr. Expert solar scientist from First Solar (FSLR) which is the leading solar company. With those two people and high growth in the next 1-5 years, stock should do great, that is why i own it. The stock is currently trading at $.12/share2. do power caps require a remote wire to turn off when you shut the car off my led lights stay on?Like Steve N. said, It's just the capacitor discharging. Capacitors are made to store the energy that the amplifier pulls straight from the battery that would normally dim your headlights, BUT there is one catch. Under extended periods of use, that capacitor can only store so much energy before it has to.... You guessed it. Discharge. And believe me, you will know when it does! Think of it as filling a bucket of water. Once it has reached its maximum capacity, it will have to dump it. In my opinion, capacitors are completely useless. If one of my customers is concerned about power issues, my first suggestion to them is to do what is called the "Big Three" wiring upgrade. For some vehicles, that will allow you to run a fairly high wattage amp without making major upgrades like adding a second battery, bigger alternator, etc... For the money you spend on a name brand capacitor, you can have a high quality wiring upgrade under your hood that will supply you up to 25% more voltage out of your alternator. If you would like me to go into further detail about the upgrade, just email me :) Hope this helps!3. Is it legal to have LED lights on my car's rims?Rims With Lights4. Has micro-biology disproven Darwin's theory of macro-evolution?Nope. If anything, it's discovered even more evidence *for* evolution. Pointing out one of Darwin's mistakes is akin to saying that Joseph Swan only invented the filament lamp, not compact fluorescent or LED lights, therefore all electric lighting is bad.5. What can I practice my soldering on?MAPLIN'S YOU CAN BUY KIT'S OF SMALL AMP'S PICKUPS,RADIOS, LED LIGHTS AND ALL KINDS FROM 5-10 THAT YOU YOU SOLDER UP YOURSELF THEY GOT ME STARTED6. Can someone tell me how i can mod my psp slim with led lights?your gonna have to open the entire psp and phsyically modify the led lights personally i wouldnt do but you can if you want to remember what you it is your own fault7. LED lights on Street Bikes Legal in Canada?Yes, no red up front8. Motherboard led lights up only. Why doesn't it work?think about power supply,at least 350 Kw to handle new motherboard9. 18 gauge wire on 18 branchesTo answer your question, yes, connect the hot leads to the hot #12 and the white leads to the white #12 neutral, wiring all the led lights in parallel. You can group or pigtail them. You need to check the load in the bedroom to make sure you do not overload the circuit but led lights have such low wattage my guess is you will be ok.Where did you buy the chandelier, online? Is it approved for use in the area you live in?10. What is a good conservation plan that i can use for my family for my electric meter?Replace old inefficient appliances by new efficient ones. Change to LED lights or fluorescent tubes (the tubes are significantly better than CFLs, but they look institutional and boring and are hard to retrofit in a home) Insulate your home better, if you use electric heat or A/C Insulate your hot water tank better, if you use electric. All the above have zero lifestyle changes :-)

Is Hooking Up Led Lights to a Timer Cost Effective?
Is Hooking Up Led Lights to a Timer Cost Effective?
No, the lights will use many more times the power that a timer, digital or analog, uses. If you talk about digital timers, the difference is astronomical. A modern solid-state timer will use no more than half a watt (5v logic x 100ma consumption), probably a lot less. In terms of mechanical timers, it's still a lot lower than 7w; Using a kill-a-watt, I just now plugged in all 4 mechanical timers I had around (at once), and the meter was still unable to measure the draw, placing all 4 at under 3 watts combined. There are different brands in that batch as well: 1 intermatic, 2 ikea, and one unknown. Think how long a tiny battery can power a mechanical watch; clocks are low-power these days. Obviously 7w > (x/1. How much does it cost to have Halo projector LED lights instaled on a 2002 truck?depends on the truck, if the truck has halo projection lights then you just need to buy the hid kit and 2 led strips that can be placed inside the headlight depending on the difficulty2. Work Lights Buying GuidePortable work lights illuminate dimly lit spaces so you can work safely and more effectively at night and during low-light projects. We put together a buyers' guide on what to look for when choosing the right area lighting tools for your needs. For the most flexibility, your portable work light should be cordless and rechargeable. The light should also have a broad flood beam pattern. Learn More A work light's power source includes your light's power supply as well as the type of battery utilized. Corded work lights provide continuous illumination; however, cordless work lights, also known as battery-operated work lights, are smaller and easier to transport. If your job takes you to different locations each day, a battery-operated light is the right choice. For best results, we recommend using a portable work light with a Lithium-ion battery, as this chemistry weighs less, it lasts longer and is more stable. If cost is an important factor, Lead Acid batteries are a satisfactory second choice to Lithium-ion. What about generator-based lights? Cordless work lights are safer to use and are more flexible, when it comes to placement. Additionally, battery-powered RALS are quiet, do not require the use of flammable fuel, have lower heat signatures and eliminate any exhaust fumes. When dealing with handheld or smaller-sized work lights, the team at BatteryJunction recommends utilizing Li-ion or Nickel Metal Hydride (NiMH) batteries. NiMH batteries offer a long lifespan and are more stable than NiCd, therefore making them reliable second choice to Lithium-ion. Alkaline-powered work lights, while convenient, are not as cost effective. What makes LED light bulbs better than CFL, incandescent and halogen bulbs? For starters, LED lights are more cost-effective and energy-efficient - lasting five times longer than CFL (compact fluorescent light) bulbs. CFL bulbs are bright; however, they give off a green hue that may have a negative effect on your workspace. This is certainly something to consider when dealing with colors and during inspections. Incandescent bulbs are typically found in the cheaper work lights, which are typically corded and therefore not very portable. Lastly, halogen bulbs, while incredibly bright, produce quite a bit of heat that may be a fire hazard in some areas. In addition to the light bulb, it is important to understand the beam output of your lamps. COB (chips on board) light rails, for example feature a cluster of diode chips positioned strategically within one module to generate an intensely bright light. COB lights are extremely popular and do not require a lot of maintenance. We chose the tripod stand as the best-designed work light because of its adjustable design and height. This gives you the ability to illuminate a broader area. Typically these RALs feature a pivoting head, which enables you to direct the output towards your working field. Portable work lights are also available in a hanging design. Due to the hanging design, these lights, though typically smaller, can still illuminate a larger area because of the higher elevation. For more up-close work, a flashlight with a magnetic base is an alternative option that may work for your needs. Mechanics, for example, may choose to attach the magnetic tailcap of a light to the hood of car, for a more concentrated output. Whether you are an experienced professional looking to enhance or elongate your workday, or you are a part-time tinkerer at home, finding the right work light for the task at hand is crucial to your success. To recap, it is important to choose a lamp that offers a broad flood beam and a base or attachment system that is compatible with your environment. Browse through our collection of portable work lights to find the right one for your needs. Have questions or need help?3. Is it legal to have pink LED lights on my rear license plate in Texas?Any color on a car besides white an yellow I illegal. I just depends on if u drive like an ****** lol. If u do not cops do not really waste their time with that. And if u do get pulled over leave the bulb on u and maybe the cop will have u change it and give u a warning

Top 10 Questions We Get Asked at Trade Shows About Amoray Underwater LED Light
Top 10 Questions We Get Asked at Trade Shows About Amoray Underwater LED Light
Top 10 Questions We Get Asked at Trade Shows At the Amoray Lighting trade show booth we generate a lot of interest with our 12V underwater LED lights. Most swimming pool professionals are looking for an underwater colour lighting solution that solves the problems they are having with limitations of existing lights on the market today. Their questions tend to focus on installation, wiring, luminescence and operation. Here are the top 10 questions we get asked by Dealers, Distributors and Pool Installers. 1) Which kind of swimming pools can the Amoray Underwater LED Light be installed in, concrete, vinyl liner and fiberglass pools? 2) What about retrofits for pools with an existing light and niche? 3) How do you retrofit an Amoray Underwater LED Light in a pool that does not have an existing light? 4) Is there a way to install the light without having to drill into the pool wall of an existing vinyl liner swimming pool? 5) How bright is it? What size pool can the Amoray underwater LED light illuminate? 6) How do you turn the light on and off and control the colours? 7) Can the remote control synchronize more than one light? 8) How much cleaning and maintenance is required? 9) What about corrosion? How long is this light expected to last? 10) How can I get more information? Yes, all three. The Amoray underwater LED light was designed for concrete pools initially. The reason for this is simple. Our design experts knew it would be much easier to adapt the light to liner and fiberglass pools once we perfected the design for the more challenging concrete pools. Everything you need for any type of pool installation is included in the package.To install an Amoray Underwater LED Light where there is an existing niche is quite simple. Connection can easily be done from our 12V 60 Watt transformer to the wire that powers the existing light and at a location where there is a 110V receptacle. At the niche, simply install the niche adaptor ring and mounting bracket provided with the light to the front of the niche. Then cut the wire to the existing light and use the approved heat shrink and glue method to connect the wire from the Amoray light. Finally, clip the Amoray light to the mounting bracket and fasten with the single set screw included and that's it. The entire process should take less than one hour. It is important to remember that all work must be done by a licensed electrician.Whether it is an existing concrete pool, vinyl liner pool or a fiberglass pool Amoray underwater LED lights can be installed much more easily than today's standard pool lights. This is primarily due to the fact that there is no niche required and the light can be fastened directly to any type of pool wall. The only stipulation is that it cannot be fastened to and outside curve or an inside curve with a radius less than 8 ft.Yes. By installing the light near the seam of two pool panels, the wire from the light can be run up behind the liner to the coping. A small hole drilled into the coping will allow the wire to be pulled to the surface of the deck. Once there, a number of options are available for getting the wire to the transformer and powers source.When positioned properly, one Amoray underwater LED light can easily illuminate a 20,000 gallon pool. Often two lights or more are used in larger pools to achieve a more dramatic effect. It is the brightest underwater LED light on the market.Amoray underwater LED lights come with a remote control. The push button remote allows for 15 colours and colour transitions for a wide variety of effects. The ideal mood can be achieved for any occasion with the push of a button. For winter, the transformer is simply unplugged from the outlet.Yes. Up to 10 Amoray underwater LED lights can be controlled with one remote control. This means that changing colours and light shows (automatic colour transitions) will all be synchronized with just one remote.Due to the low heat output of the Amoray underwater LED light there is not nearly as much algae build up on the lens as any other pool light bright pool light. That means less cleaning. As for maintenance the only thing that must be done in areas where pool water freezes in the winter is to remove the light from the bracket and place it on the pool deck until spring.The Amoray Underwater LED light has a life expectancy of 20 years. The entire light is made of durable polymer plastics that will not corrode in any type of underwater environment. Even in marine applications where salt water is a major concern, the Amoray LED light will stand the test of time. There you will find numerous videos installation manuals and a list of dealers in your area1. 6 Best At Home Anti Aging Devices for Wrinkles (2021)It can be difficult to use lasers, wands, or gel products. It may be time-consuming just to determine the right positions to get results. If you have trouble with precision and accuracy, these types of tools may not be for you. Luckily, LED light has introduced itself to the anti-aging industry. The Currentbody Skin LED Light Therapy Mask is a light therapy tool that gets the job done. If put to good use, you will see the desired results. We will discuss the reasons for this in the succeeding sections. For starters, this light therapy tool emits red light and near-infrared light.

With regular use, you will start getting results. This mask features long-lasting battery power. Therefore, you do not have to sit beside a socket just to charge it. Speaking of buying, this mask is very expensive. It may not be a solid investment because other skincare products have the same functions but come at cheaper prices. However, other products may not deliver the same results as this mask. So you may want to consider spending a little extra. It's also not a very good mask to buy if your eyes are sensitive to bright lights. You may need to close your eyes for the first few times while wearing it. It does not help either that there is no money-back guarantee. This would be detrimental for those who may not have the best reactions to strong lighting. All in all, you are still getting your money's worth with this mask product, even with its incredibly high price. The Currentbody Skin LED Light Therapy Mask is the best anti-aging device in terms of red light therapy. None The device covers your face completely so it eliminates fine lines & wrinkles faster None Supplementary gels or add-ons are not needed for it to deliver optimum effects2. Where can you buy cheap led light bulbs?u know what i get them from broken toys or any broken equipment that uses LEDs but if u want them new and realy cheap then the best choice is ebay i bet every body will agree with that3. Checking materials (cheapest possible) to be used for a solar dark-detecting LED light bulb circuitRegarding your inductor - I had a quick look on the internet to find out about joule thieves and one of the things that was said on wikipedia was: -The predominant mode of operation relies on the non-linearity of the inductor (this does not apply to air core coils). As the current ramps up it reaches a point, dependent upon the material and geometry of the core, where the ferrite saturates (the core may be made of material other than ferrite). The resulting magnetic field stops increasing and the current in the secondary winding is lost, depriving the transistor of base drive and the transistor starts to turn off. The magnetic field starts to collapse, driving current in the coil into the light emitting diode (raising the voltage until conduction occurs) and the reducing magnetic field induces a reverse current in the secondary, turning the transistor hard off.What this implies is that you have to be a little careful when choosing the toroid core. You want one that will saturate and from the your coil spec (3000uH/100 turns) it looks like a fairly low permeability type and this may not saturate as expected. I am not saying it wo not work but i am saying in my experience that when I calculate the inductance per single turn (3000uH / turns-squared) I get 300nH per single turn and it strikes me that the inductor core is a possibly a low saturation type given the size it appears to be on the videos i saw plus number of turns and likely current flow
