This is the pair of solar lanterns that attach to the top of a deck post. Each lantern??s integrated solar panel recharges its battery in eight hours of sun exposure and powers the two white LEDs for up to eight hours. The lanterns attach to the top of a deck post using the included hardware and enable one to enjoy outdoor illumination without AC access or constant battery replacement. Built-in sensors automatically turn the lanterns on at dusk and off at dawn. Each unit has a waterproof aluminum frame with matte finish that will not rust. Fits 4″ or 6″ deck or fence posts. Black, White, or Bronze. Set of two.
