Lutron Powr Savr Daylight Sensors are the coup de grace of any total system energy saving plan. Occupancy Sensors shave large amounts from electric bills by ensuring that when someone is not in the room, lights are not on. An additional savings can occur when the room has enough ambient light to obviate the need for lighting. In this case, a daylight sensor can override the motion sensor and keep lights off. This Lutron Powr Savr Wireless Daylight Sensor runs on a 10-year battery. It detects daylight, and using proprietary Clear Connect Radio Frequency (RF) technology, it sends a command to the Lutron dimmers and switches in the system, directing them to modify their light supply according to the amount of daylight present. The Lutron RF technology uses a quiet radio frequency channel with no interference. Devices allow for a dedicated network that ensures communications across the system.
