The update packages set the use of appliances, lamp holder fixed LED lights and wire powered and lamp changed to LED lights lamp. LED lights with automaticdimming and improve heat dissipation design in order to energy-saving, dual-lampapparatus used, white led light, the average power consumption of 124W, a 45% reduction comparedwith fluorescent apparatus. LED lamp life of 40,000 hours, white led light, about three times that offluorescent lamps, reduce maintenance and management burden.

Cree LED package, white led light, the luminous efficiency of its high power LED packages leads the world in the 2011 production ofproducts of the highest luminous efficiency of 161 lm / W, laboratory R & D results as high as 231 lm / W, the highest in the world.
In terms of revenue performance, Cree 2011 year (Cree’s fiscal year, calculated as the year before last July to June) by the LED chip demand as expected, lower than expectedrevenue, capacity utilization is low. But the beginning of 2011, white led light,LED lighting packageproducts and LED lighting products, grow relatively fast enough to offset the adverse effects of 2,3 quarter of 2011 chip demand is low due to the higher price, the 2011revenue was still 2010 growth.
