Cree Achieves 161 Lumens per Watt from a High-Power LED

These results demonstrate Cree’s continued commitment to deliver industry-leading performance through a constant focus on innovation and R&D. Cree’s tests confirmed that the 1mm x 1mm LED produced 173 lumens of light output and achieved 161 lumens per watt efficacy at a color temperature of 4689K. The tests were conducted under standard LED test conditions at a drive current of 350mA, at room temperature.

“Cree is inventing, commercializing and delivering LED lighting innovations that aim to obsolete the energy-inefficient light bulb,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “Our advances in brightness and efficacy come from a focus on end-to-end innovation that can enable LED lighting to address growing numbers of lighting applications while saving energy, saving money and helping to protect the environment.”

While this level of performance is not yet available in production LEDs, Cree continues to ship millions of 100+ lumen lighting-class XLamp® LEDs.
