The Lutron RRST-PRO-N-LA is a RadioRA 3 Sunnata PRO Hi-lume Smart LED Dimmer Switch Single Pole/Multi-Location Phase Selectable. The RadioRA 3 Sunnata local controls function much like standard dimmers and switches, but can be controlled as part of a lighting control system. Local lighting controls are useful in locations where single circuits of lighting need to be dimmed or switched. RadioRA 3 Sunnata dimmers and companion dimmers incorporate advanced features such as fade-on/fade-off, delayed long fade-to-off, and rapid full-on. Equipped with PRO LED technology, this dimmer switch provides superior dimming performance for CFL/LED, Triac, halogen, incandescent, MLV, and ELV lighting. The RadioRA 3 Sunnata Dimmers communicate with the system through Clear Connect-Type X Radio Frequency (RF) and must be located within 75 ft (22.8 m) of a centrally located RadioRA 3 wireless processor/gateway.
