These LED solar lamps are equipped with an AA battery that is charged by the sunlight. These outdoor solar lights can be installed under the roof, or fixed on the fence or wall. With three 0.06-watt LEDs inside, each solar lamp can provide 0.18-watt lighting. During the day, these lights convert daylight into electricity and recharge the battery. At dusk, they turn on automatically and run on the electricity stored during the day. How long the light lasts depends on the amount of daylight stored. These solar lamps are environmental friendly, energy saving, and require little maintenance. Thanks to the included mounting brackets, these solar roof lights are easy to install. Delivery includes 6 LED solar lamps, 6 mounting brackets, and screws. - Berkfield Home Outdoor Solar Lamps 6 pcs LED Square 12 cm White
