Our spherical LED solar lamp is equipped with an AA battery that is charged by solar energy during daytime and turns on automatically when it gets dark. It features a colour change in light and is the perfect decorative lighting for gardens, patios, paths, driveways, etc. With twelve 0.06-watt LEDs inside, the solar lamp can provide 0.72-watt lighting. During the day, the light converts daylight into electricity and recharges the battery. At dusk, it turns on automatically and runs on the electricity stored during the day. How long the light lasts depends on the amount of daylight stored. The solar lamp is environmental friendly, energy saving, and requires little maintenance. Thanks to the included mounting materials, the outdoor solar light is easy to install. - Berkfield Home Outdoor Solar Lamp LED Spherical 50 cm RGB in White
