The Watt Stopper doesn't so much stop the watts (in lighting and other electrical equipment), rather it ensures the efficient use of watts through energy-efficient, convenient, and accessible controls. The Watt Stopper company, a unit of Legrand, produces control panels, occupancy sensors, automatic daylighting controls, bi-level HID controls, DALI dimming controls, and plug load controls. It also makes automotive sensor lighting, HVAC, and office power control products, such as passive infrared, ultrasonic, and dual-technology occupancy sensors, and Isol energy controls. The Watt Stopper company's control products include Miro architectural wiring devices, wireless RF controls, motion sensors, and code-compliant vacancy sensors.
