The daylight harvester is an additional energy saving option for the Delta highbays. The sensor bolts on to the side of the light and optimises maximum energy savings by controlling the amount of light by automatically adjusting to the surrounding natural light.
It works well in areas with skylights or large doorway openings. In these scenarios, the sensor winds the dimmable driver down as the sun rises, or comes out from behind the clouds, and powers the driver back up to full strength as the sunlight fades again. Suits all model Delta High Bays.
