Control your lights from across the room or from the other side of the house with a Screw-in Lamp Module (PLM02)! Dim lights too, even if they didn't normally! The Screw-in Lamp Module (PLM02) works with incandescent lights and lamps (i.e. with a regular light bulb, not halogen or fluorescent). Just screw it into a light, then screw the light bulb in - it's that easy!
