Cree’s tests confirmed that the LED produced 208 lumens of light output and achieved 208 lumens per watt efficacy at a correlated color temperature of 4579 K. The tests were conducted under standard LED test conditions at a drive current of 350 mA at room temperature.
“We have now broken the elusive 200-lumen-per-watt efficacy barrier for a single white power LED,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “This is a result of improvements in blue optical output power, lower operating voltage and higher conversion efficiency. We continue to push the envelope in white LED technology to enable the highest efficiency white lighting products in the marketplace.”
While this level of performance is not yet available in Cree’s production LEDs, Cree continues to lead the industry with the broadest family of high-performance LEDs.
This is incredible. Will change lighting as we know it…
When will Norman have this product available?
Production is estimated within the next 2-3 years.
