The LMLS-400 is a closed loop photosensor that measures the ambient light level in order to automatically switch or dim one zone of lighting. It is part of a Digital Lighting Management (DLM) system and sends light level signals to control loads connected to DLM on/off or dimming room controllers. The LMLS-400 has a photodiode with an extended range of 1-1,553.
Daylight responsive on/off, bi-level, tri-level or dimming control for one lighting zone
Extended tube model accommodates thicker ceiling materials
100 degree spatial response for optimal detection of ambient light level
Automatic calibration and configuration; optional hold off setting to maximize energy savings
Photodiode corrected to match the photopic response of the human eye
Can be calibrated in any daylight condition
