This dimmer switch works with up to 150-Watt of dimmable LED/CFL or 600-Watt of incandescent/halogen, allowing you to control multiple bulb types on the same circuit. It is designed to control a broad range of dimmable LED and CFL bulbs from a variety of brands including Philips, Cree, GE, EcoSmart and Lighting Science. Use the rocker to adjust the light level for any activity or set the preset level to ensure lights always turn on to your desired light level. Advanced features include delayed fade to off, which allows time to exit a room or to get into bed before the lights turn off.
