Measures true color temperature and intensity of natural sunlight or any other lighting source. Enables indoor lighting to be regulated to match the actual natural sunlight outdoors. IP67 rated for outdoor rooftop installation. Also suitable for indoor applications.

The Crestron SolarSync™ Photosensor (GLS-LCCT) enables the ability to regulate indoor lighting to match the intensity and color temperature of actual daylight outdoors. A single SolarSync™ photosensor installed on a building’s rooftop measures the exact correlated color temperature (CCT) and luminosity (lux) of the natural daylight, and reports it to a Crestron® lighting control system. Accordingly, the control system adjusts the indoor RGB lighting fixtures to simulate the effect of being outdoors.

SolarSync photosensors may also be deployed indoors to sense the light output from artificial lighting sources, allowing fixtures to be precisely adjusted to achieve a specific desired effect, or to correlate lighting conditions between separate spaces. The ability to adjust both the intensity and color temperature of indoor lighting to specific values can be utilized to positively influence the circadian rhythms of night-time workers in an office or manufacturing facility, or to aid healing patients in a medical or psychiatric facility. It can also be employed to benefit the experience of patrons in a public mall, museum, casino, or theme park.

The GLS-LCCT is a calibrated color temperature and intensity sensor capable of achieving exact measurements consistent with CIE 1931 2° Standard Observer color coordinates. It is composed of a compact, IP67 rated housing with acrylic dome, suitable for installation indoors or outdoors. Built-in heating elements prevent snow and ice from accumulating on the dome to ensure reliable operation year-round.

The GLS-LCCT is 24VDC powered and energy-efficient, requiring just 70mW in warm weather and a maximum of 5W when heating itself. Power and communications are provided via a Cresnet® connection to the lighting control system.
