LED : Single 100W compositive leds Work voltage: AC85-265V 50/60Hz Power Factor:>0.9 Luminous Efficiency:90-100lm/w Efficiency of Power Supply:>95% Beam Angel:130d Color Rendering Index:>Ra80 Color Temperature:2700-8000k Life Span:>50000Hrs 1. Uses single powerful LED (30w---100w) as the light source,using our proprietary LED encapsulation.Utilizes the special design of multichip single module.Imported high brightness semiconductor chips. 2. Integrative design for heat sink and housing;The LED is closely connected to the surface.The heat from LED is removed through the heat dissipation wing and also by the air ventilatio.The design ensures a 50,000hours life-span for the LED . 3. Compared with traditional sodium lights,it can save electricity more than 70%. 4. No ill glare;no abrupt and frequent flashes.The design ensures that bad glare is eliminated,vision fatigue . 5. No delay start;no waiting .It can reach its normal light as soon as it is turned on.And avoid the long time start process of the traditional lights. 6. Environment friendly.Does not have lead,hydrargyrum,and any other contamination.No pollution to the air .
