A Light Emitting Diode (LED) is a semiconductor device which converts electricity into light. LED lighting has been around since the 1960s, but is just now beginning to appear in the residential market for space lighting. At first white LEDs were only possible by "rainbow" groups of three LEDs -- red, green, and blue -- by controlling the current to each to yield an overall white light. This changed in 1993 when Nichia created a blue indium gallium chip with a phosphor coating that is used to create the wave shift necessary to emit white light from a single diode. This process is much less expensive for the amount of light generated.

Each diode is about 1/4 inch in diameter and uses about ten milliamps to operate at about a tenth of a watt. LEDs are small in size, but can be grouped together for higher intensity applications. LED fixtures require a driver which is analogous to the ballast in fluorescent fixtures. The drivers are typically built into the fixture (like fluorescent ballasts) or they are a plug transformer for portable (plug-in) fixtures. The plug-in transformers allow the fixture to run on standard 120 volt alternating current (AC), with a modest (about 15 to 20 percent) power loss.

LED Lighting and more has a wide variety of LED lighting products as well as solar and wind options for home and office. CFL bulbs, once considered the best option for reducing lighting costs have been found to contaminate our soil and water tables with mercury upon improper disposal. LED bulbs offer long life and energy savings as high as 80% compared to standard bulbs. LED lighting can replace most of your household bulbs and with solar panels becoming less expensive, solar powered LED lights can be used for outdoor spotlights and motion sensors.
