Sandstorm-proof and seawater resistant PV street lighting fixture, equipped with high power LED Lamp. Recommended for sunny regions, like Africa, desert countries, South America, Philipines. High brightness corresponds to 80 watt mercury light. Very long maintenance-free system lifespan, by use of efficient LED lamps and electronic 24V-60V PWM driver. Microprocessor system control for lighting and charging. Pole and brackets are hot dip galvanized (on surcharge with a UV-resistant painting). The screws are made of stainless steel. This solar light is maintenance free - only the solar panel should be cleaned occasionally with water. Our systems are provided with serial numbers, wich can be validated to protect against malicious copies.
