Lutron Ariadni fan controls are designed to replace or match your traditional toggle style switches. This combination control can be used to operate both light and fan from a single switch – no need for two separate controls for the light and the fan. The slider on the left adjusts your fan between 3 quiet speeds (Low/Medium/High), while the slider on the right adjusts your light level. The toggle switch only controls the lights ON/OFF, allowing you to turn on the fan without /having to turn on the lights. The Ariadni combination fan and light control fits into a traditional wall plate opening and can also work with your existing multi-gang wall plates. Available in 6 gloss colors. Pairs perfectly with Lutron Fassada wall plates for consistent color matching (sold separately).
