LED lights are not only the wave of the future, but also the efficiency wave for saving money. And like most things of value, they are costly upfront. Therefore, it is in your best interest to know exactly which of the available LED downlights will work in the application you are considering.
Begin by deciding if you want a downlight that will dim or not. Dimmable lights are more expensive and might not be exactly what you expect. LED dimmable lights do not act like incandescent or even fluorescent lights.
They will maximize the light at the top end without difficulty. What is different is the low end of the dimmer switch. It will turn off at approximately twenty five percent of power.
It will not dim as much as an incandescent bulb. Now you choose to dim without being disappointed by the limitations. Compatibility with your existing recessed ceiling cans is usually not a problem.
LEDs require a bit more depth but most cans can be modified to accept them. There are cans that are compatible without modification. Usually you can find a chart that lists compatibility but do not rely on them.
Only the electrician can reliably determine compatibility. Electricians can also modify cans to accept LEDs. The lights come in many diameters.
Most examples range from 2 inches to 6 inches. The style of cans and the number of surrounds to hide the cans are nearly unlimited. This means you will not have to compromise on style or design issues.
There are different bulbs available in downlights. Bulbs are a given. You can just replace the existing bulbs with these if the bases are compatible.
You can also get LEDs specifically made for ceiling cans. This would work well in new construction. And there are puck lights available as well.
Of course you will, in the long run, save money on electricity. That is why you need to view LEDs as an investment. Because of their long life, you will not be buying LEDs at anything like the rate you buy incandescent or even compact fluorescent bulbs.
Knowing what application you want use your LED Downlights for will prepare you to ask the questions that count. Choose between straight on/off or dimmable. Know there are differences between new construction and replacement applications.
And have a great time finding the style and design that will please you without worrying about limited selection.
