Designed for outdoor use, this fixture will turn itself on when it detects motion. The wattage rating of the sensor must be at least as high as the total watts of the fixtures.įor example, if you have two fixtures, each rated to hold a 100-watt bulb, the sensor must be rated to handle at least 200 watts. Brand-new, still sealed in original box, Intelectron Motion Detector Security Light - model BC8930K.
Theyre usually labeled as replacement sensors for floodlight fixtures, but you can attach one to a mounting plate and use it as a remote sensor.īefore you buy a replacement sensor, add up the wattage ratings on the fixtures it will control. If new wiring isnt an option for you, consider sensors that give you similar results but with little or no rewiring.Ĭhoosing a sensor Home centers and hardware stores carry motion sensors (20) that look like the ones you see mounted on floodlights. In some situations, you can fish wires through finished walls.īut in many cases, this project is only practical where you have open studs, as in an unfinished garage (as we show), or during a major remodeling project.
