What WattStopper does
WattStopper is a brand unit of Legrand North America specializing in networked commercial and industrial lighting control systems. The portfolio centers on Digital Lighting Management (DLM) platforms — encompassing load controllers, room controllers, power packs, and network components — alongside wireless occupancy and daylight sensors, fixture-integrated sensors (Luminaire Level Lighting Control, LLLC), the Wattstopper PLUS and DLM panel lines, and the FSP-600 fixture sensor photocell for outdoor applications. The company serves commercial buildings (offices, healthcare, education, hospitality, manufacturing) and, through Legrand's adorne and radiant with Netatmo product lines, the residential smart lighting market, integrating with Amazon Alexa, Google Home, and Apple HomeKit.
The core technology is a wired and wireless networked lighting control stack with fixture-level sensors and centralized panels, supplemented by OEM integration partnerships (notably with Visionaire Lighting for outdoor fixtures). WattStopper monetizes through hardware sales of sensors, controllers, dimmers, and panels distributed via Legrand's authorized electrical and lighting distributor network, the Legrand US e-commerce platform, and OEM/embedded channels, with quote-based project pricing and no publicly disclosed list pricing. As a wholly-owned subsidiary of Legrand — a global electrical and digital building infrastructure company established in nearly 90 countries — WattStopper benefits from the parent's distribution scale, R&D base, and capital, while operating under its own registered trademark and brand identity since 2002.
