Designed with your safety in mind, Globe Electric's plastic Weather Resistant Motion Sensor Activated Twin Light Security Light (79770) uses two 150-watt maximum halogen bulbs to provide a bright even light for your home (bulbs sold separately - item is compatible with Incandescent and LED bulbs as well). The 180-degree detection zone motion sensor turns on when motion is detected to keep you safe all night long. The duration of the light is adjustable from 6-seconds to 1 minute and 30 seconds so you can create the ideal security light for lighting needs. A manual override switch allows you to turn the lights on and off with an indoor wall switch so you can easily control when you use your light. Plus, the adjustable light heads can be directed to achieve maximum light coverage and a handy test feature allows for trouble-free set-up. Your home, garage, office or building will never feel safer.
