High lighting efficiency We use the single powerful LED (30W~140W) as the light source. The color temperature is 4500~6500K and its color rendering index is over 80. Long life-span and low power consumption LED can be used up to 50,000 hours. Its life-span is over 10 years. Compared with high pressure sodium lamp, it can save electricity around 60%. Compared with incandescent lamp, it can save electricity around 80%. Reduce construction charge It can save over 70% of the investment of pre-embedded wires, transformer, electric rack and cable. This is equal to the price of slap-up street lamp (high pressure sodium lamp). High reliability and environment friendly There is no pollution from LED. It’s the ideal GEP products for lighting
