LED Bulb Replaces Incandescent Bulb

A 40-watt GE Energy Smart® LED bulb from GE Lighting (Cleveland, OH) will be available later this year or early 2011. The new LED bulb is expected to consume only 9 watts, provide a 77 percent energy savings, and produce nearly the same light output as a 40-watt incandescent bulb - while lasting more than 25 times as long.

LED Edge-Lighting Solution

Global Lighting Technologies (GLT), Inc. (Brecksville, OH) now offers LED edge-lighting solutions that focus light into a high-performance backlight, or light guide. Because the LEDs are located on the edge of the light guide, there is better optical control for color and uniformity, fewer LEDs, better repeatability, and the thinnest possible lighting solution.
