Photosensors

The LMLS-600 dual loop photosensor from WattStopper combines two daylighting control technologies to increase energy savings in applications with skylights, without distracting lighting changes. Developed in cooperation with the California Lighting Technology Center (CLTC), it combines open and closed loop daylighting control strategies, measuring ambient light and daylight. The new photosensor features automatic commissioning, including self-calibration and establishment of setpoints. Additionally, it recalibrates itself every night to adapt to reflectance changes in the space, such as changing furniture or retail display layouts and lamp lumen depreciation. Learn more >
