In the search for energyefficient lighting, LEDs have proven to be the most efficient bulbs available. Energy Starrated LEDs use at least percent less energy than traditional incandescent bulbs and last times longer, according to the U.S. Department of Energy. LEDs even outdo CFL compact fluorescent lighting bulbs in efficiency, primarily because they have twice the lifespan of CFLs. LEDs are more efficient than both incandescents and CFLs because they emit light in a targeted direction instead of scattering it in all directions and they dont require or emit great amounts of heat. Incandescents and CFLs release most of their energy as heat percent and percent, respectively. See References

Connecting a diode to an electrical current excites the electrons within the diode, them release photons, which we see as light. The of the light is a direct result of the energy gap in the semiconductor of the diode. This means that LEDs produce a spectrum of s easily and brightly while using very little electricity to do so.

LEDs do not require standard bulb shapes to work efficiently; however, this shape allows LEDs to replace bulbs in typical residential lamps.

The biggest problem for consumers when purchasing LEDs for residential lighting is the upfront cost. Depending upon the and brand of the bulb, LEDs can cost two to six times the price of CFLs. When replacing bulbs for multiple lighting fixtures, the idea of spending hundreds of dollars on bulbs deters many potential customers. However, LED production is not only improving but increasing, which will mean greater affordability for consumers in the near future. See References

LED stands for light emitting diode. A diode is an electrical component with two terminals which conduct the electricity only in one direction. With an electrical current, the diode emits a bright light around the small bulb. Typically, diodes have been used in many technologies such as radios, televisions and computers as an electrical component for conduction. See References

Energy efficiency is all the rage with good reason. Energyefficient lighting choices lower utility bills and lessen the burden on nonrenewable energy sources, which account for percent of energy production in the U.S. see References . LEDs, the most efficient lights on the market, are starting to appear alongside incandescent and compact fluorescent bulbs in hardware and homegoods stores. They are, however, a mystery to many, as their inner workings are quite a bit different from standard bulbs.
