NetBright Spotlights contain patented NetBright technology that allows the lights to communicate with each other, creating a wireless network for sophisticated perimeter security. Each spotlight provides 200 lumens, is battery powered, motion activated with auto shut off, and can be installed in less than 5 minutes with the included screws. When one NetBright Spotlight detects motion, all others on the network will activate. Easily create up to 4 separate lighting zones that work independently from each other; each zone can hold up to 50 lights within 150 feet of each other.
