Lutron Ariadni Dimmers help you achieve the ideal lighting for your home. With the traditional toggle-style switch and captive linear-slider, you have the ability to adjust the light to your preferred level. This dimmer is for single pole applications where it is controlled from only one switch. It matches existing toggle-style switches, so it fits perfectly where your traditional light switch resides. Wall plates are sold separately in matte, gloss and stainless Steel finishes.
