During the day, the solar panel converts sunlight into electricity and recharges the internal batteries. At night, the light turns on automatically and uses the energy stored in the batteries. The number of hours the light stays on depends on the amount of sunlight received the day before. Up to a maximum of approx. 8-10 hours. Warm Tips: 1. Position your solar ground light product in a location where it can be exposed to maximum sunlight during the day. Do not try to position your solar light in a place where the solar radiation is reduced, eg. under trees or shrubs. 2.
