XLamp LEDs have now achieved a 100% improvement in performance over the past 17 months. They can deliver either 25% greater brightness with improved efficacy, or they can deliver up to 55% greater brightness at the same efficacy when compared to the previous generation of XLamp LEDs.
XLamp® XR-E LEDs provide the light foundation for a new line of high-performance outdoor lighting fixtures, THE EDGE™ by Beta LED™. THE EDGE line of LED luminaires is designed for street, parking lot, parking garage, walkway and building-mounted applications.
the overall lighting efficiency is higher than compact flourescent which usually max out at 60 lumens/watt The best flourescent tubes can go up to 104 lumens/watt.
Conventional incandescent light bulbs are typically in the 10 to 20 lumens per watt range, while compact fluorescent lamps (CFL) range from 50 to 60 lumens per watt.
The company Cree achieved 131 lumens/watt with LED lighting in 2006
Getting to the best LED lighting would get overall lighting efficiency up to 22%. Up from the 2-3% efficiency of incandescent and 7-10% of typical CFL and 15% efficiency of the best flourescents.
Lighting accounted for approximately 9% of household electricity usage in the United States in 2001. CFL can save 60-80%. LED could go up to 90% saving or another 50% beyond CFL.
