Fixture Mount Daylight Harvesting and Photocell Sensors

The NexLight fixture mounted photocell and daylight harvesting sensor is a convenient self-contained control solution. Basic on/off units are capable of directly switching lights off when ambient levels are high enough that desired overall light levels will still be maintained. Lights will be switched back on once ambient level falls below the desired setpoint.

Units with the daylight harvesting (dimming) option track a space's overall illumination and dim connected lighting to achieve energy savings. During times of high daylight contribution to a space, controlled artificial lighting will be gradually dimmed to a minimum dimmed level. During times of low or no daylight contribution, controlled artificial lighting will increase back up to its maximum level. The sensor can also be configured to switch lighting off completely in maintained high daylight conditions. Additional configurable parameters include high & low trim levels and fade rates.

All photocells provide the option of selecting the ambient light threshold (e.g., setpoint) from a range of preset values or running an auto-selection mode where the unit will determine the setpoint based on the measured amount of light it is controlling.
