The automatic outdoor LED path lights, 35 lumens of light for dark walkways or stairways. NetBright technology allows the wireless path lights to communicate with other NetBright path lights and spotlights, so when one activates with motion, all others on the network turn on. The motion-sensing path lights activate when they detect motion within 15 feet and automatically shut off after 20 seconds without motion. Expect about one year of light on each set of batteries. Install the battery-powered path lights in minutes with the included mounting hardware. Versatile mounting options include ground or deck installation. Create up to 4 zones with up to 50 NetBright lights on each to light separate areas of your yard for sophisticated, affordable home safety and security lighting.
