These are the solar-powered lights that mount flush to steps, decks, or walkways to provide abundant lighting without obstruction. With a depth of only 2 1/4", each of the five 1 1/2"-diam. lights fit into prepared holes using the included 1 1/2"-diam. countersink spade bit (power drill required), ensuring that illuminated footpaths, decks, and stairs are free from obstacles. Each light provides 17 lumens of warm white light and is connected using 9'-long cords in-between each. The integrated 5" H x 4" W x 1" D solar panel secures to the ground with the included stake and bracket. A built-in sensor automatically turns on the lights at night, providing up to 10 hours of light from a full charge of its included rechargeable AA batteries; it can also be turned on/off manually.
