Cree announced its high-power LED light efficiency breakthrough 186lm/W

LED lighting company CREE announced that its high power white light LED efficiency has been achieved 186lm/W, this effect is the highest level of industry research report.

This result suggests that Cree continues to enhance its LED performance. Cree test results show that, when the relevant color temperature in the 4577K, LED can produce 197lm light output, to achieve 186lm/W light effect. The test is carried out at room temperature and driving current of 350mA in a standard test environment for LED.

Although this level of performance of the LED is not currently in the Cree production, but Cree will continue to supply the industry's most extensive flux of 100+ lumens LED products. (http://www.solidstatELighting.net/documents/view/cldoc.php? Id=118466#top)
