The Lutron Skylark SF10P-WH white rocker and slide switch dimmer is the original designer-style slide dimmer from Lutron. It features a convenient rocker switch that turns the lights on and off, and an easy-to-use slide control to adjust the light for any activity. The Skylark replaces any designer-style switch and works with existing multi-gang decorator wallplates. It is CSA certified, UL listed and has a one year warranty. This dimmer is for use with fluorescent lighting.
