LED Holiday Tree at Port Discover
LEDs are the future of light, and may soon overtake Compact Fluorescent bulbs as the best choice for efficient home lighting. LEDs don’t have filaments, the part that easily burns out in ordinary bulbs, and they do not product heat like incandescent bulbs.
LEDs also last far longer than standard bulbs, usually 50,000 hours, but sometimes up to 100,000 hours (that’s 30 to 40 years in normal service), compared to Compact Florescent bulbs’ 3,000 to 10,000 hours. Unlike Compact Florescent bulbs, LEDs do not contain mercury, and therefore do not pose as much of an environmental problem in disposal.
The Light Up the World Foundation is using the energy efficient nature of LEDs to bring reading light to Third World Countries all over the world. With the energy it takes to power a single 100-watt Incandescent Bulb, they are lighting up 100 LEDs using the solar, wind, or pedal power.
