How Do I Unscrew a Flushmount Ceiling Light Fixture That Seems to Be Stuck?

　　Author ：Green earth– LED Strip Lights manufacturersThe lighting fixtures commonly used in large lighting places such as indillants, factories, workshops, and gymnasiums are called LED industrial mine lamps. Do you know what light fixture belongs to the LED industrial mine light? Let's tell you about Xiaobian.Human pursuit has not stopped, from the beginning of the original fire to the present various lighting fixtures. It is also because of the emergence of the electric lamp, so it has changed the social model of humanity. In the past, everyone will follow the sunrise, life, but now, this model has changed, because the LED industrial mine light will be at night.“Lit up”Let everyone live a change, becoming an indispensable tool in life.In summary, do you know what LED industrial mine lamp is lighting?

The color rendering index of 100 watt led street light is much higher than that of high-pressure sodium lamp. The color rendering index of high-pressure sodium lamp is only about 23, while the color rendering index of LED street lamp is more than 75. From the perspective of visual psychology, the illumination of LED street lamp can be reduced by more than 20% on average compared with that of high-pressure sodium lamp.100 watt led street light has automatic control energy-saving device, which can achieve the maximum possible power reduction and power saving under the condition of meeting the lighting requirements of different periods. It can realize computer dimming, time-sharing control, light control, temperature control, automatic inspection and other humanized functions. 100 watt led street light SL03 description 1、Modularization & plug technology, convenient maintenance, no need any tools. 2、Cellular heat dissipation and the whole structured dissipation technology, good heat dissipation performance. 3、Double coupling IP65 protection level, super waterproof performance. 4、Single LED lamp damaged does not affect the other lamp working. 5、Multi-channel constant current driver power supply, single module can be hot plug. 6、Human ergonomics light distribution, uniform road lighting. 7、Multiple modules free combination, so the LED modulariztion provides a great lighting solution for industrial applications. 100 watt led street light shape structure For the external protection of 100 watt led street light, it is recommended to use soft ceramic heat dissipation paint for LED lamps. This spray type soft ceramic heat dissipation paint can be directly sprayed on the outside of LED lamps and lanterns, which is easy to operate and can be adapted to various shapes of heat dissipation structures, and can also be adjusted to different colors to meet the needs of landscape design. The soft ceramic particles in the spray type heat dissipation paint are treated by nano technology. The fine particles are not only easy to be operated by the spray gun, but also make the heat conduction particles on the same coating area more and denser, make the area of temperature volatilization and dissipation larger, and make the heat energy of LED lamps quickly transmit out. Soft ceramic heat dissipation paint is a thermosetting material, which conforms to ROHS environmental protection and Safety specifications. The construction procedure is simple and does not need any special machines and tools. After baking, it can withstand the high temperature of LED for a long time without quality change. LED street lights, LED landscape lights, or LED billboards that are used outdoors will also face acid and alkali damage from wind and rain, acid rain, bird droppings, air dust, black smoke emissions, etc. Therefore, the spray type soft ceramic heat dissipation paint must have the characteristics of acid and alkali resistance, and the range of acid and alkali resistance is PH3 11, which can effectively protect the appearance of LED outdoor lamps from erosion. 100 watt led street light SL03 specification Model No.: SL03–100W Power(W): 100W Light Efficiency: 100–150Lm/W Voltage(V): AC100–277V CRI(Ra): >70 Power Factor： >0.95 CCT(K): 30006000 Environment Temperature :-4050℃ Life Time(H) : ≥50000 Ctn/Pcs: 1 LED: Epistar/CREE Model No.: SL02–180W Power(W): 180W Light Efficiency: 100–150Lm/W Voltage(V): AC100–277V CRI(Ra): >70 Power Factor： >0.95 CCT(K): 30006000 Environment Temperature :-4050℃ Life Time(H) : ≥50000 Ctn/Pcs: 1 LED: Epistar/CREE 100 watt led street light for sale 100 watt led street light for sale,Shanghai JingRui lighting is a professional enterprise integrating research and design, production, sales and service.Our main products include 100 watt led street light, LED Grow Light, HID Flood Light, Ballast and Bulb, etc. which are widely used for mobile light tower, construction sites, stadium, parking lot, road, ports and docks, etc. Free Quotes.

Why?I'll tell you, my choice is LED headlights.The following is my understanding of HID and LED.Advantages of Xenon Lamp1. The color temperature of xenon lamp ranges from 3000K to 12000K, of which 3000K is pure yellow, with the strongest penetrability in rainy and foggy days.4300K white to yellow, is the most comprehensive color temperature in rain, fog, sunny days and many road conditions (this is the standard for the original high-grade cars).5500K is the most natural color that is slightly white and close to sunlight.The 6000K color temperature contains more blue components, thus presenting blue and white light.Simply put, the higher the color temperature, the whiter the color, and the poorer the relative penetration, the shorter the illumination distance.2. HID is three times higher than halogen lamps in brightness efficiency, which has an obvious effect on improving the visibility of driving at night and in fog.3. Xenon lamps emit more than 2 times the luminous flux of halogen lamps. At the same time, the efficiency of converting electric energy into light energy is also increased by more than 70% compared with halogen lamps. Therefore, Xenon lamps have a relatively high energy density and illumination intensity.4. Save 1/2 of electricity. Halogen lamps consume more than 60W of electricity while xenon lamps only need 35W of electricity.5. Since xenon lamps have no filament, the problem of scrapping due to filament breakage will not occur. The service life of xenon lamps is much longer than that of halogen lamps. The service life of xenon lamps is equivalent to the whole operation time in the average service life of automobiles.6. Xenon lamp will not go out instantly in case of failure but will go out (or light up quickly) by gradually darkening, so that drivers can gain time in driving at night and pull over in an emergency.Disadvantages1. The requirement of a light-gathering is high. Special xenon lamps must be used. There are two factors for not gathering light.(1) The mismatch between bulb and lamp leads to, for example, installation of xenon lamp light source for lamps using halogen lamp light source; (This is also why it is not effective for car owners to change xenon bulbs directly. )(2) Bulbs and lamps are not properly installed, and the focus is not properly adjusted, which requires professional and experienced light distributor.2. Some models with the self-checking function will have fault lights on when they are installed because the bulb power of the original car is high (55W) and the power of the xenon lamp is low (35W), so the modified car will give an alarm when its power is not enough. As a xenon lamp, its starting instantaneous current is 8A, while the original car was started at 6.2A, so the circuit settings of the original car do not match. Professional installers are required for decoding and matching.3. The quality of the product is not up to standard. Incorrect installation may cause electromagnetic interference. This requires a professional installation technician to install.Advantages of LED Lamps1. Long service life, generally up to tens of thousands or even hundreds of thousands of hours. In the future, LED will be used for automobile lighting lamps, and lamps will not need to be replaced throughout the service life of the automobile.2. High efficiency and low energy consumption. The LED light source can directly produce red, amber and other colors required by automobile lamps without color filtering, without loss, and the utilization rate of electric energy is as high as over 80%.3. The light quality is high and belongs to environmental protection products. Basically, there is no radiation and "green" light source.4. LED has a simple structure, internal support structure, and is sealed with transparent epoxy resin around, with good seismic performance. 5. No delay in lighting, fast lighting response speed (nanosecond), suitable for objects with fast-moving speed.6. It is suitable for low voltage operation and can be completely applied to automobiles.7. LED occupies a small volume. Designers can change the lamp mode at will, thus diversifying the car shape. Automobile manufacturers favor LED, which is completely determined by the advantages of LED itself.Of course, compared with xenon lamps, LED lamps also have the following disadvantages1. The requirements of lamps are extremely high-since the requirements of lamps are more stringent at the single point of the light-emitting focal plane, this problem is also the reason why the lighting effect of LED lamps is most affected.2. High cost-Take LED reversing lamps as an example. One LED reversing lamp is close to 30 yuan, while the price of one bulb is only 5 yuan, most of which is the cost of LED lamps. High prices cause ordinary cars to be unable to install LED lights and the market cannot be popularized.3. The difficulty in popularizing LED car headlights is due to the fact that the LED light source is installed in a relatively sealed headlamp assembly, which has poor heat dissipation and easy light attenuation due to poor heat dissipation treatment, thus affecting the service life of the headlamp.4. There is no unified industry standard and the quality of products is uneven.5. It is difficult to design a light type. Because the vehicle lighting is different from the domestic lighting, the width, range and range requirements of the vehicle lighting are much higher than those of the domestic lighting.In general, xenon lamps and LED lamps have their own advantages and disadvantages. Judging from the matching of current light sources and lamps, if the lighting effect is the final judgment standard, the effect of HID xenon lamps is obviously higher than that of LED lamps which are not perfect enough, but judging from the overall development trend of science and technology, LED lamps will definitely be the mainstream in the future.Maybe you want to know more about LEDs in cars, you can visit myblog(vantenled.blogspot.com) or mywebsite(www.vanten.co.uk). It will have some good idea

Now more and more countries are plan to make solar led street light fixture.Because traditional street lamps need to use a lot of electricity and have labor costs,and solar led street light have a lot of benefits.Firstly,the designer need to know the technical data for the traditional street lamp.Probably speaking,the ratio of power between traditional street lamps and solar street lamps is 1:5.It mean that if AC sodium street lamp or AC halogen street lamp power is 100W,then you can chose 20 Watt led solar street lights.Secondly,solar led street light fixture designer need to calculate the solar panel and battery capacity.The solar panel and battery capacity should base on the light working time.Normally We design 20 Watt led solar street lights working time is 12 hours per night.Because it will have a lot of human appear in the road from 6PM to 12PM,and it will have less human or nobody appear in the road from 1AM to 6AM. In order to save the power,we can set 20 Watt led solar street lights work in 100% power in 6 hours,50% power in another 6 hours.Then when it is in 6PM to 12PM,the light is very bright.When it is in 1AM to 6AM,the light will be use in 50% power status,save half of the power.Thirdly,traditional street lamp pole have not included solar panel support and battery support.So it need to add solar panel support and battery support in solar led street light fixture project.The solar panel support size should base on solar panel drawing,solar panel drawing include solar panel size and solar panel frame hole position.Use suitable screw fix the solar panel on the solar panel bracket.Following these steps,we can make solar led street light fixture smoothly.Mostly,this is a one time investment,after 2–3 year’s using,you can call back your investment and use free power later.FOSHAN MARS SOLAR TECHNOLOGY CO.,LTDAdd:2 floor,№3 Building, Lianfeng industrial zone,ZhangCha Chancheng District,Foshan City,Guangdong Province.ChinaMob:86–757–82705605 86 15302966051Email:admin@solarpowermanufacturer.comwww.solarledfactory.com·RELATED QUESTIONWhy is the speed of the centrifugal compressor is kept higher than that of centrifugal pump?Centrifugal gas compressors are limited by a stress limited tip speed. In general, smaller frame sizes have higher nominal speeds than larger units mainly due to the larger impeller stresses in larger wheels. Mathematically, stress is directly proportional to the square of tip speed. With less denser materials, you can drive to higher speeds. A typical example would be an automotive turbocharger compressing air, made of single aluminum stages where 60,000–100,000 RPMs are not unheard of. The process gas compressor are limited to lower speeds due to a steel alloy makeup and practical constraints of rotor dynamics and thermomechanical stress in multi stage units.

Most often the red wire in a lighting circuit is a switch leg. Very likely there is a black/white pair coming in from the panel, black/white/red going to the switch box, and then black/white continuing from the switch box to some other outlet. If this is the case, the black is the hot wire from the panel and will be attached to one side of the switch, the red will be attached to the other side of the switch, and returns power to the light box when the switch is on. Personally I would take things back apart and test it out with a meter to confirm, but you can also take off the switch cover and check which color wires are hooked up to it. If it follows the pattern I described, then moving the black wire of your new fixture over to the red wire in the box should solve the problemWhen replacing an old chandelier with a new ceiling, there was one red wire, two white wires tied together and two black wires tied together.I had capped the red wire and tied in the remaining wires to their respective colors.

In fact, the lumens of LEDs are increasing rapidly. In 2009, the number of lumens per watt of mass-produced LED has reached 100 lumens, and this number is growing rapidly. The corresponding theoretical system of heat transfer has been mature, and the heat transfer means we can use are basically clear: conduction, convection, radiation and phase change heat transfer. Therefore, the measures we can take in heat transfer or heat dissipation are visible and limited.

We also need a ladder to change a bulb 11' from the floor. It can take 20 minutes for 1 bulb! This is one reason that we have changed to the longer lasting (and more economical) low-energy bulbs.I would be delighted to have wall lights instead. Retro-fitting them would however be even less economically sound.Higher than average ceilings mean ladders to change the bulbs in ceiling fittings, and this extends the maintenance time and convenience for staff enormously. Even normal height ceilings mean that a chair is needed to swap a bulb out. Wall fittings are so much more convenient for both staff and customers, reducing the time taken to get light again!As Michael Forrest Jones says - anything other than a simple bulb swap requires the power to be cut to the whole circuit (which may be more than just a few rooms). This makes it very awkward to do emergency repairs after dark! -- Been there done that... Go with wall fittings that can be isolated in-room!In short:I have ceiling lights.I don't like them, as they are awkward for maintenance.Replacing them would be expensive and extremely difficult - basically a total rewire of the hotel lighting system.Design engineers are not stupid. they note the first 2 points!

Outdoor lighting is often an afterthought in exterior facelifts and landscape designs, something not remembered until the plants are dug, the deck is built and the house is repainted. If you find yourself in this kind of dark spot, don’t despair: We talked to professionals for some simple ideas that will make a big, bright impact. First, a few basic rules: 1. Take your home’s architectural style into account: If you have a formal brick Colonial, for example, says David Benton, an architect at Maryland’s Rill Architects, stick with traditional porch pendants and wall sconces. “I think it’s always key to keep things simple,” he says. “They look more elegant that way.” If you have a house that’s a bit more modern, you can play with something contemporary, or even funky or farmhouse style. 2. Don’t undersize your lights. Do you have a large front yard? Make sure your light fixtures are large enough that they can be seen from the street. Benton says he tends to go “just a little bit larger” than he thinks he’ll need to. 3. Think about the big picture. Once you’ve got the front lighting set, think about how much total lighting you want to do. “You want to err on the side of subtle,” says Mark Oxley, president of Outdoor Illumination in Bethesda. “It’s better to start with less. Then you add to it if you think it’s not enough.” ●It’s important to take into account your house’s style, especially when looking for front-entry lighting, says David Benton, an architect at Bethesda’s Rill Architects and the lead architect for the 2014 D.C. Design House’s facade. For a Colonial, rambler or mid-century modern house, Benton likes the Lakehouse wall-mount lantern in Americana Bronze. “It’s a utilitarian fixture that can go either contemporary or traditional. Perfect for over a garage or mudroom door.” ($390, www.barnlightelectric.com)●Karen Olson Weaver, who specializes in exterior and landscape lighting as principal lighting designer of Olson Weaver Lighting in Alexandria, uses gas lamps in her projects in older neighborhoods such as Georgetown and Kalorama. Plow & Hearth’s Old Brooke light, in three colors and sizes, is inspired by early gaslight design but uses a bulb. For sizing, Benton says that a good rule of thumb for lights flanking a front door is that they should each be a quarter of the size of the door. If you only have one, it should be a third of the size of the door. ($44.95-$84.95, www.plowhearth.com) ●Put candles in Terrain’s copper Mansard lantern and you’ll get the comfort of flickering light. If you prefer to avoid the mess of fire and wax, try battery-operated LED candles, Olson Weaver suggests. “At some point, things have to be practical,” she says ($68-$98, www.shopterrain.com).●Benton likes retro-inspired string lights, such as World Market’s Edison-style 10-bulb string lights, for creating a “party atmosphere” that you can leave up all summer. “These are really fun on a deck, crisscrossed overhead. It’s a nice general light, and they’re festive as well,” he says. ($24.99, www.worldmarket.com)●“When you bring lighting outside, people are drawn to that,” Olson Weaver says. “It’s an inexpensive way to create another space in your house. You could have no chairs on your terrace, and you could put a little lantern out there, and the whole party will move out there.” She likes NotNeutral’s Season metal lantern (in four colors and three sizes) and says that it would be a good lantern to hang on shepherd’s crooks around the garden or next to a grill ($54-$162, www.allmodern.com).●Pendants look nice in multiples over a dining table on the porch, Olson Weaver says. With a more unusual design, you’ll want to see them in person to check the dimensions and material quality, she says, but Design Within Reach’s pendant barn lamp would be pretty safe to order on the Web because it’s a pretty basic design — hard to go wrong ($315, www.dwr.com). ●Like the look of a pendant but don’t have a porch ceiling? Olson Weaver also hangs pendants from archways, pergolas and even trees (for instance when the tree limbs extend over a bench). “From the terrace looking out, it creates a visual focal point,” she says. “It draws the eye out there.” Bocci’s cast-blown glass 14 Series outdoor pendant seems elemental in nature — ideal for creating an idyll in the garden. ($370-$385, www.lumens.com)●Before ordering a light fixture for the outdoors, make sure that it’s designed to withstand the elements, Olson Weaver says. The Superior Moravian Star hanging light in clear, rippled glass or white glass is rated for a damp location (meaning it can be outdoors but not exposed to water — on a covered patio, for example). “Just one of these fixtures would make any outdoor space heavenly,” Benton adds ($455, www.shadesoflight.com).●Mark Oxley, president of Bethesda outdoor-lighting firm Outdoor Illumination, seconds Olson Weaver’s recommendation to see and touch fixtures in showrooms before ordering. He also recommends buying a brand known for quality and dependability, such as Hadco or Kichler. Kichler’s cast-brass deck light would add sophisticated safety lighting to stairs and decks ($76, www.kichlersuperstore.com).●String lights make a big impression without a complicated installation. Pottery Barn’s cafe string lights in bronze or galvanized metal would be a great tool to define a patio or seating area in a larger outdoor space ($39.50-$89, www.potterybarn.com).●Path lights are a pragmatic way to create ambiance outdoors. “There are a lot of different styles that can be really functional but also be fun,” Oxley says. “But if you’re doing something fun, you want to be careful because that cute little acorn light can look great one or three times, but if you put 12 of them along a walkway, it can get out of hand.” Kichler’s copper path lights make for a subtle style statement ($184).●Solar-powered fixtures might be best if electricity is a challenge. Soji’s hanging solar lantern is made of heavy-duty nylon and collects sunlight in the day to create a glow at night. It also comes with LEDs, a battery and a base-unit accessory to convert it into a tabletop lantern ($19.99, www.allsopgarden.com). ●Benton, Oxley, and Olson Weaver all love string lights for a festive option that works no matter the season. The star shape of Luna Bazaar’s white organza string lights is a fun twist on the standard string lights.
