|Cree R&D result breaks 200 lumen per watt barrier|
|04 Feb 2010|
|Cree is claiming a new R&D record for a white high-power LED.|
High-power LED manufacturer Cree claims to have set a new laboratory record for a white, high-power LED of 208 lm/W. Just two months ago, Cree reported an R&D result of 186 lm/W.
The 208 lm/W LED produced 208 lumens of light output 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.
As acknowledged in Cree's press release, this level of performance is not yet available in Cree’s production LEDs. The company says that this R&D result passes a "significant milestone" within the solid-state lighting industry, as well as demonstrating Cree’s "relentless drive" to increase the performance of its LEDs.
“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 [chip] 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.”

|[Dated Sept 9, 2010]. That's an excellent result. It would be even better if cree could supply stock, as at the moment there is very little and long lead times reported from out Taiwan branch.|

|Will Cree deem fit to enter into a marketing/manufacturing base at India with ITI Limited (A Govt. of India Undertaking), a $10 billion company, currently focusing on massive lighting solution for Street light, home light, office, factory and border light. |
