LED lighting is a lamp or
other light that uses light-emitting diodes (LEDs) as a source of illumination.
Most lighting comes from an incandescent or fluorescent light bulb. Although
they are different than the traditional bulb, LED bulbs are available that can
be put into traditional lamps and used like most other light bulbs. They are
much more efficient than incandescent or fluorescent options, however.
Light-emitting diodes are semiconductor devices that convert electricity to light by using the movement of electrons. They were invented in
There are many consumer advantages to LEDs over incandescent or fluorescent light bulbs. LED lights consume much less energy: they are 300% more efficient than compact fluorescent lights (CFLs) and 1,000% more efficient than an incandescents. They have a very long life, with about 50,000 hours of use at 70% of their original power. This works out to eight hours a day for 13 years at 70% power. A typical 60-watt incandescent bulb may last about 1,000 hours.
Quite small, LEDs are often used in clocks and watches and as indicator lights in cars. They have fast switching, so they are good in remote controls and lights that are turned on and off frequently. Their directional nature means that they are best used under kitchen counters, in stairways and hallways, or as reading lamps, landscape lighting, and office lighting.
LED lighting comes in many forms, including downlight, troffer light , panel light or clusters. They are as simple to install as other types of lighting and can be found where consumers buy other bulbs and lights.
