The Leviton R01‑066DF‑00I combines advanced lighting control with smooth, quiet fan operation in a single, elegant Decora‑style device. Engineered for modern LED/CFL compatibility while supporting traditional incandescent and halogen loads, this dual-function control gives homeowners precise command over both fan speed and light level—perfect for bedrooms, living rooms, home offices, and any space where comfort and ambiance matter.

This model integrates two independent slide controls—one dedicated to dimming the lights and the other for selecting fan speeds (Low/Medium/High). Leviton’s specialized circuitry minimizes fan motor noise at low speeds and includes an LED‑optimized dimmer design that prevents flicker and allows for fine low‑level brightness adjustment. The slim housing fits into standard wallboxes and supports multi‑gang installations, making it a versatile upgrade for any home.

Whether you want whisper‑quiet airflow, customizable lighting ambience, or energy‑efficient control over your ceiling fan light kit, the R01‑066DF‑00I provides a refined, reliable solution built to Leviton’s performance standards.
