Daylight Harvesting enables intelligent lighting sensors, like the SCN and DLA products, to automatically detect ambient sunlight shining through skylights and dim their light output accordingly. The dimming target is equal to the light levels in the facility when it's dark outside, and is established using a one-time Daylight Harvesting Calibration procedure.

Daylight Harvesting is an advanced feature of the SiteWorx Tune lighting control application. It allows facilities to save up to an additional 30% of lighting energy normally consumed by LED lighting luminaires during daylight operating hours.
