WattStopper LMLS-400 Closed Loop Photo Sensor

The WattStopper LMLS-400 Closed Loop Photosensor is a digital lighting management sensor that continuously monitors ambient daylight and automatically switches or dims a single lighting zone within a WattStopper Digital Lighting Management (DLM) system. It uses closed-loop daylight harvesting with photopic correction to mimic the human eye, supporting On/Off, Bi-Level, Tri-Level, and Dimming control modes for a single zone, and communicates over a DLM Local Network via RJ-45. Key specs include a 24 VDC input, sensing range of 1–1,553 foot-candles with a 100° spatial response, ceiling-mounted ABS plastic housing in white, and an operating temperature range of 32°F to 131°F (0°C to 55°C). Ideal for office buildings, educational facilities, healthcare institutions, conference rooms, retail spaces, government facilities, and other commercial settings where automatic daylight harvesting and energy savings are desired.
