LED bulb

Compact fluorescents are great, and much more efficient than incandescent bulbs, but there’s something even better on the horizon: LED lights. In fact, you have probably already seen traffic lights that use high-lumen Light Emitting Diodes, which consume a tenth of the electricity of an incandescent bulb with a red filter.

Because diodes are solid, rather than gas-filled tubes, LEDs are much more resistant to shock and wear, lasting more than a hundred times longer than the conventional incandescent bulb, and up to five times longer than a compact fluorescent.

LED lights are not yet produced in sufficient quantities to be inexpensive. But as the virtues of these cool and efficient bulbs become better known, prices will continue to drop. Watch this space.
