The Light It! wireless remote control LED puck lighting system turns lights on and off from up to 60 ft. even through walls, unlike infrared systems. A dimmer is included, and the two lights automatically turn off to save energy. It is perfect for attics, workshops, under cabinets, crawlspaces, garages, night lights, RVs, campers and boats. It installs in minutes with no wiring or tools required. Up to 20 lights can be programmed to operate from one remote. It is possible to program four independent circuits with multiple switches.
