Operation and Storage Condition
• Operation Ambient Temperature -40 to +50°C, Relative Humidity 20~90%
• Input Voltage 85~265V AC, 50/60Hz
• Storage Ambient Temperature -40 to +85°C, Relative Humidity 10~90%
• Mounting Height : Suitable for 5~10m height

• high quality power supply, input voltage 100-277V. The power efficiency is morethan 90%, power factor greater than 0.98, UL compulsory certification.
• Adopting Lepower led light sources and ZAG lens technology, 8% lightefficiency higher than the same type lights in the market, with higher lighttransmittance up to 98%.
• Duct type thermal design, reduce the weight of the light and ensure goodheat dissipation, lower luminous decay, and also extend life span of the leds.Adopting the popular CHEM modular design, effectively reduce the followingmaintenance cost. 
• Low energy consumption，matching high efficiency constant-current driver, 60%energy saving; with good resistance to over-current, over-voltage, lightning,high temperature, which fully ensure long life span and high stability of theproducts.  
• Durable lights with long life span up to 50000 hours; No need frequentreplacements of lights and regular maintenance.
• Green environmental protection, no UV light and infrared radiation, nomercury pollution.
• Nice appearance and non-fouling properties, Protection class IP66.
• Work without strobe, fast transient response；A wide range of working voltage.
• 2pcs 1W chips are packaged in one led, which ensure high stability andalso reduce the death rate of the leds.
