I have a standard outdoor Motion Detector made for controlling incandescent lamps. I need to operate a relay from the Motion Detector. My relay coil is 44k ohm, The 100 watt bulb I tested with is 18 ohms. The Motion Detector will work with the light but not the relay, it will run relay if it is connected in parallel with the 100 watt bulb, What do I need to do to replace the bulb so I can use the relay by itself?
