Your best interests will be served if you are aware of a few requirements of LED downlights before you go shopping. Because they are more expensive than other bulbs, you want to get it right the first time. You will save time as well as money when you shop well prepared.
You need to decide on whether your application will require dimmable lights or just simple on/off lights. The dimmable LEDs do not respond in the same way that compact florescent or incandescent bulbs do.
LEDs do not respond over the full power range, as does an incandescent bulb. Nor does it get brighter as if warms up like a compact fluorescent. The LED responds from one hundred percent power down to twenty five percent. Any lower than that and the bulb turns off. If this limitation is acceptable then go ahead with dimmers. If not, at least you will not be disappointed by the performance.
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.
These bulbs come in diameters from about two inches to six inches or more. The ceiling cans that are specifically made for them come in many styles and designs. You will not have to limit your choice in that respect. There are many fixture surrounds to choose from as well.
Bulb shapes vary according to application. Replacement bulbs are available if the bases are compatible. There are specific ceiling bulbs and their cans and these are perfect for new construction. Puck lights are also easy to find and have many uses.
The investment aspect of LEDs is important. Because these bulbs are far more expensive, it is wise to remember that the savings will come from less electricity use and longer life. Much longer life can be expected when compared to either of the other options.
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.
For displays or standard use, LED downlights offer a variety of solutions. You can buy dimmable LED downlights to change the mood of the room.
