Masco. The wireless Verve Living lighting control system requires less wiring and has lower material and installation costs than other systems, the maker says. Verve light switches use energy-harvesting radio frequency technology, which turns the motion of flipping a switch on or off into the energy needed to transmit the radio signal. Wiring only needs to run from the utility panel to a central controller, and then to each light. 800.542.3789. www.vervelivingsystems.com.
