Product Monday: Synch Indoor CCT & Brightness To Daylight

6 days ago | lightnowblog.com | David Shiller

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.
LED-to-LED Rebates & Upgrades

1 week ago | lightnowblog.com | David Shiller

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.

LED + SSL Chinese manufacturer, EXC Technology, claims to have surpassed the 250 lumens per watt (lm/W) efficiency barrier—a significant milestone in the pursuit of more energy-efficient outdoor lighting. The company, based in Shenzhen, unveiled its MYS4C/MLS6C module, reporting a luminous efficacy of 250.5 lm/W. EXC attributes this high efficiency to a combination of advanced optical design, high-quality LED chips, and precision manufacturing processes.
Researchers Find UV Light Reduces Bird-Building Collisions

1 week ago | lightnowblog.com | David Shiller

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.
