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 1-6,553 footcandles (fc), and photopic correction to mimic the human eye, for precise measurement of visible light.

Questions & Answers

I recently installed a LMCP-LI24 panel and am curious on which light sensor would work best with this panel. I want the 0-10v dimmed LED lights in the atrium to dim, or shut off when the sun is shining but be full bright at night and dim accordingly.
