Our most powerful solar floodlight includes three adjustable lamps, each with three white LEDs to provide improved light output. Each lamp features a ground stake and surface-mounting bracket for a variety of installations. Each lamp is connected to a remote solar collection panel via 10 feet of weatherproof cable. The solar panel swivels in any direction for optimal solar energy collection. The sun charges fixture batteries by day and turns on automatically at night with no electical wiring or cost to operate
