The Gama Sonic Everest II Solar Lamp is a double solar lamp head for both residential and commercial properties that features a bold statement of modern design. This commercial grade solar post light fixture comes with all necessary hardware for mounting and can be placed on any 3-inch outside diameter pole. Stylish and easy to install, this solar post light is the perfect energy and money saving alternative for commercial electric or gas-powered outdoor lighting. The Everest II is constructed of weather-resistant, rust-resistant cast aluminum with a powder-coated black finish. It incorporates our cutting-edge GS solar LED light bulb technology and provides 360-degree illumination. At dusk, the powerful solar lamp automatically turns on and provides a direct downward illumination at a brightness of 500 lumens in the high setting and 250 lumens in the low setting in a warm white (2700K) color temperature. Once the battery has been fully charged for 3 days in direct sun, the light will last from dusk to dawn up to 5 nights in the high setting and up to 10 nights in the low setting. No wiring is needed. Just place this solar post light in a spot with ample direct sunshine and let the sun do the rest.
