The Lutron Radio Powr Savr LRF2-DCRB-WH is a wireless, battery-powered ceiling-mount daylight sensor designed for commercial daylight harvesting applications where wired sensor runs are impractical. Operating at 434 MHz via Lutron’s Clear Connect RF technology, it measures ambient light levels across a 01,600 lx (0150 fc) range and transmits continuously to compatible dimming or switching devices, providing open-loop daylight compensation that linearly tracks changes in viewed light level without manual sensitivity adjustment. Compatible with Radio Powr Savr occupancy/vacancy sensors and Pico wireless controls, it features front-accessible test buttons for intuitive commissioning, multiple ceiling-mount options for various ceiling materials, and a rated 10-year battery life. White finish.
