Let Lutron turn the lights off for you and avoid wasting energy, The Maestro Vacancy Sensor and eco-dim Dimmer are integrated to combine the elegance and technological sophistication of Maestro controls with the energy savings and superior performance of a vacancy sensor powered by Lutron exclusive XCT technology. The vacancy sensor detects when a room has been vacated and automatically turns the lights OFF so you’ll never inadvertently leave the lights ON. An adjustable timeout function allows you to set the time before the lights turn OFF, while the manual on setting ensures your lights only turn ON when you switch them ON a great way to save even more energy. The eco-dim feature guarantees 15% energy savings over the standard switch, and is designed to extend incandescent or halogen bulbs 3 times. With a sleek design, the Maestro eco-dim Dimmer with vacancy sensor is a great energy-saving addition to any room in your house, including kids’ rooms, bedrooms, dining rooms, garages, and basements. Matching Claro wallplate included.
