Sandstorm- and weatherproof PV street lighting fixture, equipped with double side high power LED Lamp 120w. Recommended for sunny regions, like desert countries, Arabia, South America, Africa. Very high brightness, even brighter than 2* 250 watt hps sodium light. 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 consist 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.
