Microprocessor-based Smart Dimmer technology provides true dimming from up to 10 locations when used with Maestro companion dimmers, compatible with standard single-pole and 3-way wiring. Double-tap brings lights to full brightness instantly, and press-and-hold fades lights off over 10 seconds; LED indicators display current light level and function as a locator light. Gloss finish, black, fits a standard designer wallplate opening.
