A light-emitting diode
, or LED, is a type of solid-state lighting that uses a semiconductor to convert electricity into light. With 25,000 hours or more of useful life, LED lighting lasts up
to 20 years without needing to change a bulb. LED bulbs are also useful in that they can produce energy savings of 92% on your lighting bill by lasting 25 times longer and run constantly for more than 3 years.
LEDs make your commercial
or residential property brighter and safer. In addition to the benefit of
safety, LED bulbs can last much longer because unlike incandescent bulbs —
which release 90 percent of their energy as heat — LEDs use energy far more
efficiently with little wasted heat.
LEDs are used in a wide
range of applications because of their unique characteristics, which include
compact size, ease of maintenance, resistance to breakage, and the ability to
focus the light in a single direction instead of having it go in many
LEDs contain no mercury, and a recent Energy
Department study determined that LEDs have a much smaller environmental
impact than incandescent bulbs. They also have an edge over compact fluorescent
lights (CFLs) that are expected to grow over the next few years as LED
technology continues its steady improvement.
