These solar ground lights are perfect lightings for gardens, patios, paths, and balconies. Each solar lamp is equipped with a Ni-MH battery charged by the sunlight. During the day, the lamps automatically absorb the sunlight energy and convert it into electricity to charge the battery. There are eight LED beads in each lamp, which emits bright light in the evening. The light automatically turns on when it gets dark and turn off during the daytime. These solar lamps are energy saving, and require little maintenance. You do not need to pay the electric bill for the light since it is solar powered. The solar lamps are designed to be water-resistant and suitable for daily outdoor use.
