The national center for quality supervision and inspection of lamps and lanterns, senior engineers, senior auditors YuAnQi said in landscape lighting, backlighting, LED has been basically can live long, but in the field of general lighting, LED can not achieve the high efficiency and long life.
China lighting electric appliance association director liu singer told reporters: “the more energy-efficient LED lights is indisputable, but its actual life has yet to be test.” Reporter refer to the instructions on the use of the many LED the lamp that shield an eye, found that most of these products service life of the nominal is 50000-100000 hours. If calculated according to use 4 hours a day, these products should have ten years of life.

Life assessment problem solution
, director of the institute of dalian university of technology of optical Zou Nian) said that the problem is what LED lighting reliability evaluation.
