The Sunnydaze Black Ball Solar Powered Fountain with LED Light brings a piece of modern sculpture into your outdoor space with a unique twisted base and spherical accent cast in black resin. The water gracefully flows from the top of the ball down to the top of the pedestal base where it then recirculates with the help of the submersible solar pump. when you combine the beauty with the soothing sounds, your outdoor space will be the place to sit and relax. Use solar power to energize your outdoor decor. No more unsightly extension cords running across the yard and hogging your outdoor plugins. Mount and conceal the solar panel in a sunny place and enjoy! The Solar Battery Backup option allows you to harness solar energy even when there is no sunlight! The rechargeable battery pack charges throughout the day (with or without the fountain running) so you can enjoy the gentle water sounds in the evening as well. To run on battery mode simply press the Battery On/Off button. The battery will now power the pump.
