The LMLS-600 is a dual loop photosensor specially designed to optimally dim or switch lighting in applications using skylights or other
top-lighting daylight sources. It is part of a Digital Lighting Management (DLM) system, and sends commands to control loads connected
to DLM switching or dimming room controllers. The LMLS-600 incorporates two separate photodiodes to independently monitor the
available daylight and the delivered indoor light levels. Both photodiodes have photopic correction to mimic the human eye for precise
measurement of visible light.
The photosensor installs to the curb or frame of a skylight using the supplied adjustable mounting bracket. Once in place, the
LMLS-600 is fully self-calibrating, requiring no special knowledge or light meters to achieve optimal operation. This automated
process, directed from floor level with a handheld configuration tool (LMCT), or from a program running on a laptop computer (LMCS/
LMCI), learns the characteristics and response curves of the controlled lighting and reflectances of the interior space, and establishes
appropriate setpoints. These parameters can be adjusted, if desired, to customize operation.
The unique dual-loop control algorithm delivers optimal energy conservation and light-level maintenance, even in changing conditions
such as low sun angles and partly cloudy sky conditions, as well as changes to interior reflectances caused by changing décor. The
photosensor continuously commissions after installation, accounting for changing lumen output of light sources and redecoration of
interior spaces. The LMLS-600 operates on Class 2 power supplied to a DLM local network by one or more DLM room controllers.
