LED downlights are an excellent alternative to incandescent light bulbs. They use less energy than their incandescent counterparts, which means fewer energy bills. LEDs also last longer than other types of lighting, with the average LED light lasting for 11 years when used for twelve hours a day. An added benefit of LED downlights is that they do not produce any harmful materials, unlike incandescent and fluorescent tubes, which contain mercury, which must be disposed of properly.
