L.E.D (Light Emitting Diodes) are only a few millimeter in length but they are packed with major technological benefits, making them a real alternative to conventional lamps.
LED's aren't in fact a lamp at all - but a semiconductor that converts electricity directly into light. It is for this reason that the life of a LED is so long - sometime hundreds of thousands of hours.
LEDs are generally available in red, amber, yellow, green or blue. White light is generated with special technology.
The operating costs associated with L.E.D. are extremely low because of their long life, low energy consumption and low maintenenace costs.
