How the Solar Garden Light Works? 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 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. The solar disk lights automatically switches on at night via the built-in light sensor. This sensor may not work if the lights are positioned in a location where bright light falls on the unit during the dark hours, e.g. from another outdoor lamp. NOTE: 1.Make sure to turn on the switch before use. 2.Make sure expose it to the sunshine for 6 to 8 hours to fully charge before using it. (lack of sunny or cloudy weather will lead to insufficient charge and shortens use time). 3.Please put the panel under direct sunshine, adjust the light angle to illuminate the perfect spot and adjust the solar panel angle for optimum sun exposure.
