White LED (light emitting diode) lamps consume less than a quarter of the electricity that fluorescent lighting does, and the lamps last about ten times as long. A Light Emitting Diode (LED) is a semiconductor device which converts electricity into light. LED lighting has been around since the 1960s, but is just...

light-emitting diode n. LED. A light-emitting diode (LED) (pronounced /ˌɛliːˈdiː/ [1], or just /lɛd/), is an electronic light source. The first LED was built in the 1920s by Oleg Vladimirovich Losev, a radio technician who noticed that diodes used in radio receivers emitted light when current was passed...
