T1L (10BASE-T1L) Ethernet technology has significant potential to accellerate building automation, by enabling the reuse of existing wiring to upgrade network infrastructure without costly running of new wiring. Building management systems (BMS) can been run on T1L and this can have implications for lighting systems. T1L Ethernet is a long-distance networking solution that leverages a [...]

  Here is my latest article published in the May issue of LD+A Magazine: Al Jamea-tus-Saifiyah University’s Nairobi, Kenya campus stands as a testament to the seamless integration of historical inspiration and contemporary design. Drawing from the rich architectural heritage of the 10th-century Fatimid era, the campus design incorporates verdant gardens and tranquil spaces that [...]

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 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, [...]

In March 2025, the National Electrical Manufacturers Association (NEMA) published the ANSI/NEMA C137.9-2025 standard, titled “Networked Lighting Control Systems Configuration Report.” This new standard was developed through the efforts of industry leaders, including the DesignLights Consortium’s (DLC) Levin Nock and working group co-chair Jason Jeunnette, with the goal of streamlining the configuration and verification process [...]

  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, [...]

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 [...]

Govee has introduced its latest home lighting innovation, the Strip Light with Skyline Kit, designed to transform ordinary living spaces into dynamic, visually engaging environments. The standout feature of the Skyline Kit is its floating wall-washing effect. Unlike standard strip lights that simply illuminate a surface, this system projects a broad, upward glow that washes [...]
