"Optimising each LED design element was critical in achieving the performance reached by Cree's new prototype LED bulb," said Nick Medendorp, vice president of research and development, Cree lighting. "The technology embodied in the new 170 LPW concept LED bulb is enabling us to develop higher-performance and lower-cost Cree LED luminaires. By pushing the limits of what is possible, Cree continues to strive to develop new technology that uses less energy and provides unmatched light quality and value to our customers."
Third party testing by independent lab OnSpeX confirmed that Cree's new 170 lumen-per-watt prototype LED bulb delivered more than 1250 lumens and consumes only 7.3 watts. The bulb uses Cree TrueWhite Technology to deliver a CRI of 90+. As an efficiency comparison, a traditional 75-Watt incandescent light bulb produces 1100 lumens, which is only 14.6 lumens per watt.
