These solar wall lamps are great decorative lighting for gardens, patios, paths, and balconies. They can easily be assembled on a wall or a fence. This solar wall lamp is equipped with an AA battery charged by the sunlight. During the day the solar panel converts daylight into electricity and recharges the battery. There're three 0,2 W LED beads inside, with 2 shining in white and 1 in yellow. The yellow LED bead turns on automatically when it gets dark, while the white ones turn on once the built-in motion sensor detects movement at night. Our solar wall lamp is energy-saving, and requires little maintenance. You do not need to pay electric bill for the wall light since it is solar powered. Delivery includes 2 lamps.
