This is the solar powered light that mounts to an outside wall to illuminate stairways. Ideal for locations where installing new electrical service for lighting isn't practical, the light's 4" H x 2 1/4" solar panel collects enough sunlight to power four LEDs that project an 18" cone of light to illuminate steps and risers. A built-in sensor detects the level of light present, automatically turning on the light at night, providing up to 10 hours of light from a full charge of its integrated battery; it can also be turned on/off manually. Housed in a sturdy, weather-resistant, brushed stainless steel frame. 5 1/2" H x 2 3/4" W x 3" D. One Light. (1 lb.)
