Lighting Design, Products + Technology The Crestron SolarSync Outdoor Daylight and Color Temperature Sensor (GLS-LCCT) enables the ability to regulate indoor lighting to match the intensity and color temperature of actual daylight outdoors. A single SolarSync sensor installed on a building’s rooftop measures the exact correlated color temperature (CCT) and illuminance (lux) of the natural daylight, and reports it to a Crestron lighting control system.

A decade after the widespread shift from fluorescent and HID lighting to LEDs, early adopters are now facing the need to replace their first-generation LED fixtures. Traditionally, utility rebate programs have not supported “LED-to-LED” upgrades, focusing instead on the initial move away from legacy lighting. However, as LED technology and energy efficiency standards have advanced, this is beginning to change.

Energy + Environment Bird-building collisions are a significant issue, causing millions of bird deaths annually as birds fail to recognize glass windows as barriers. Recent research and technological advancements highlight the potential of ultraviolet (UV) light as a promising solution to this problem, leveraging the unique visual capabilities of birds. Most bird species possess the ability to see ultraviolet light, a spectrum invisible to humans.
