Skylark 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 wall plates.  Reverse phase ELV technology reduces energy consumption and provides smoother, more precise dimming control, especially at low levels of light.
