White light LED from Shenzhen Xingchen Optoelectronics Co., Ltd is made with choice chips from famous factories and characterized with peculiar white light low attenuation technics. You can produce low attenuation super bright LED light sources out of this white light LED. Luminous flux of single LED can reach up to 3.8-4.5lm or above(For 20 degree angle products, the luminous intensity is 20000mcd;for 120 degree angle products, the luminous intensity is 2000mcd). Luminous flux of LED with 2 chips can reach up to 9---10 lumens. Attenuation as for 1000 hours is under 15%, this can be listed in the advanced level in our country. Low-attenuated white light series for lamps are characterized with wide angle, high luminous flux, low heat, low attenuation and price.
