Cree launched the United States more than 1300lm LED bulbs luminous flux

U.S. Cree developed more than 1,300 lumens luminous flux, luminous efficiency of 152lm / W high power LED bulb warm white, its performance has exceeded the U.S. Department of Energy for the 21st century lighting set up goals.

The third-party OnSpex laboratory identification, the more than 1,300 lumens luminous flux of LED bulbs, power consumption of only 8.7 watts, while the light color rendering index of 91, corresponding to warm white color temperature of 2800K. Compared with the traditional 75-watt incandescent lamp can produce 1100 lumens of luminous flux, but the efficiency is only 14.6lm / W, Cree bulb efficiency is far higher than the result.

Cree founder NealHunter introduced, 150lm / W LED lighting will make the United States, 16.5% lower power consumption, power consumption back to 1987 levels. Cree LED lamps success of this efficient, one hand because of Cree in the LED type, optical components, drive and power supply, etc., for a number of optimization; also benefited from the U.S. Department of Energy-related issues, is now still with the United States Cree Department of Energy for a series of cooperation to promote energy-efficient solid-state lighting round.

In 2007, the U.S. Department of Energy under the Energy Independence and Security Act guidance, the establishment of a "light tomorrow," Lighting Grand Prix, the game belongs to the 21st Century Act lamps inside the third category, to encourage new inventions, instead of being on the market widespread use of inefficient lighting technology. 21st Century Lighting Competition Bill provides as follows: greater than 1,200 lumens luminous flux, luminous efficiency greater than 150lm / W, color rendering index greater than 90, color temperature 2800-3000K range.
