Characteristics: The lamp pole is of high-quality steel, hot-galvanized, surface electrostatic powder coated, erosion resistance and anti-UV. Lamp shell uses aluminum alloy casting, with advantages of glossy surface and fluent curve. Reflector uses the high-purity oxidized aluminum, oxidation sealing treatment, good optical character. Uses inner-change bulb structure with air purification respirator to ensure high-output of the luminous flux and to reduce the attenuation of reflection coefficient. Protection class IP65. Suitable light source: 40W-180W LED streetlight, 150W-400W high or low pressure sodium light, ceramic metal halide light, non-pole light. Voltage/frequency of power source: DC24/AC220/50Hz. Light source height: 6.0-12.0m. Solar modules: High efficiency mono/poly crystalline silicon solar modules. Working time: 8-10 hours. Consecutive cloudy days: 3-6 days. Controller: Uses micro-computer chip, digital circuits, integrated sensor technology, with main and secondary lights alternating work, or both work till the set time, then the main light off but the secondary on. Battery: The wholly sealed, valve-control style, free-maintenance, lead-acid battery or High efficiency lead crystal battery. Available location: All regions with annual sunshine time more than 2200 hours. Note: Due to differences in solar energy resources, solar lighting system should be configured according to users’ specific needs, installation location and solar radiation.
