LEDs use a fraction of the power required by conventional filament bulbs, and their solid-state design allows them to withstand shock, vibration, frequent switching and environmental extremes without compromising their long life of typically 100,000 hours or more, according to Ledtronics.
Major steps have been taken in the area with the development of new “doping” technologies which increase LED light output by as much as 20 times over earlier generations, and allow the production of daylight-visible LEDs in virtually any colour.
In addition to red, yellow and amber/orange, which were the first available colours, LEDs are now available from leaf green to ultra blue. Even white light, long thought to be a virtual impossibility, is now available as a light emitting diode. LED bulbs are available for thousands of different applications in industries ranging from automotive and aviation to security and interior decorating.
