Powerful and robust - there is no electrical grid required. Recommended for average sunshine regions, like Europe, southern Russia, New Zealand. 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. All components are surfaced with a grey, scratchproof 2-layers UV-resistant coating. 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.
