The LMLS-500 is an open loop; multi-zone photosensor that measures the daylight contribution in order to automatically switch or dim up to three zones 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-500 has a photodiode with an extended range of 1–1;500 footcandles (fc); and photopic correction to mimic the human eye; for precise measurement of visible light.
