The Echoflex Correlated Color Temperature Photo Sensor (TAP-41) is a wireless, self-powered photo sensor with correlated color temperature (CCT) sensing technology. Designed for indoor use, the TAP-41 sensor has two selectable light intensity ranges. One range supports light intensity levels suitable for monitoring fixture output for closed loop daylighting. The second range is ideal for monitoring exterior light levels for open loop daylighting control.
