This Pack of 2 Stainless Steel Wall Mounted Solar LED Lights makes an excellent solution for outdoor locations that don't have a typical electrical supply available. Designed for wall-mounted applications just about anywhere, the lights work well to illuminate a doorway, back deck, stairway, recycling area next to the garage, a shed, or other location in need of illumination. Each light features a square-shaped solar panel that soaks up the sun by day, which effectively recharges its Ni-Cd AA battery (included) for nighttime use. When the sun goes down, the lights turn on automatically, for a foolproof maintenance-free way to keep dark areas well lit. Depending on the amount of sunlight received during the day, the lights can provide up to 10 hours of illumination at night. The super-bright LEDs last up to 100,000 hours, and the rechargeable batteries will last for about two years before needing to be replaced. Housed in corrosion-resistant stainless steel, the CE-certified lights offer safe water-resistant performance from one season to the next, and installation's a breeze (no wiring required). The pair of energy-efficient solar-powered lights each measure 7 inches long by 2 inches wide by 5 inches high.
