The Wattstopper Radiant RHFB83PTC is an 8A 2-wire fluorescent preset dimmer for single-pole and 3-way control of dimmable 2-wire fluorescent fixtures on 120V circuits. The 2-wire configuration eliminates the need for a neutral at the switch location, simplifying retrofit installations in standard switch boxes. Tri-Color finish includes interchangeable faceplates in white, light almond, and ivory.
