LEDs

LEDs are energy efficient light sources with a long lifetime

LEDs are small electronic semi-conductor chips which radiate light when current flows through them. They come in both coloured and white versions and typically use 0.1-5 watts.

Examples of uses for LEDs

Within a few years LEDs will dominate homes, offices and streets in both the private and public sector.
