LED bulb electrical performance: LED bulb rated at a nominal supply voltage and rated frequency, normally open and maintain ignition. When the LED bulb to work under nominal rated supply voltage and rated frequency, the difference between the nominal power of their actual consumption should not exceed 10% 20w bulb quotes, 5W bulb above the power factor of not less than 0.75 . LED bulb light performance: CRI (indoor use) not less than 65. The initial light effect (without masks) should not be less than 80lm / W. led energy saving light Features: Long life: light-emitting semiconductor chip 20w bulb prices, no filament bulb 20w wholesale, no glass bulbs, not afraid of shock, not broken, the service life of up to fifty thousand hours (incandescent life only There are one thousand hours, the general energy-saving lamp life of only eight thousand hours). Health: Healthy light contain ultraviolet and infrared little less produce radiation (ordinary light contains ultraviolet and infrared). 20w bulb Quote | Hang Li saving (certified) | Shaanxi 20w bulb provided by Anyang Hi-tech Zone Heng Lai energy-saving lamp factory.
