Compared to traditional wired sensors, Tresco Lighting’s innovative new Wireless Door Sensors are easier to install and eliminate the hassle of messy wire management. Using RF technology, the sensors automatically turn lights on when a door is opened. Mount them to the bottom or side of your cabinet frame, then sync with the push of a button to the receiver (sold separately) and enjoy fully illuminated cabinets without the hassle or mess of running wires. Sensors are available in black or nickel, run on long-lasting CR2025 batteries and are backed by a 3-year warranty.
