White LEDs, A Revolutionary Concept In LightingWhite LEDs, A Revolutionary Concept In Lighting

TECHNICAL FEATURES OF LEDs :

White LEDs are 'Light Emitting Diodes', a typeof semiconductor. They are the newest item in

today's lighting technology. Unlike other lightsources, theseWHITE LEDs can take a lot ofpunishment from vibration, heat and severe cold.

WHITE LEDs can be made waterproof, and putinto a lighting package with 2 to 1000WHITELEDs. They can be used for street lights, signlighting, spot lighting, Home lights or anything else.
