Occupancy and Daylight Sensors nLight®

WebnLight occupancy sensors have several lens options, allowing for multiple mounting height & coverage pattern requirements. Dual technology occupancy detection can also be added for instances where occupants are stationary for long periods of time. nLight daylight sensors provide a range of daylight harvesting features. WebPhotocells and motion sensors differ in the way they trigger lights to turn on. Photocells detect changes in light levels and react accordingly. Motion sensors respond to any physical movement within their range.
