Cree, the LED lighting market leader, announced that its white power diodes achieve 161 lumens per watt of luminous flux, the highest level in the industry's research and development report.
These results once again underscore Cree's long-term commitment to delivering first-class performance through continuous focus on innovation and R&D. Cree's tests show that a 1mm x 1mm LED produces 173 lumens of light output at 4689K color temperature, achieving 161 lumens per watt. The test was performed on a standard LED at room temperature with a drive current of 350 mA.
John Edmond, one of Cree's founders and director of advanced optoelectronics, said: "Cree is constantly inventing, commercializing and providing innovative LED lighting technology to ban incandescent bulbs with low energy efficiency. Our advantages in terms of luminous flux and efficacy come from the point to Innovative focus, enabling LED lighting technology to meet growing lighting applications while saving energy, saving money and helping to protect the environment."
While LEDs that achieve this level of performance are not currently in volume production, Cree has delivered millions of lighting-grade XLamp® LEDs with more than 100 lumens.
