The U.S. Department of Energy’s GATEWAY program has released a report describing four exterior SSL projects that have been completed at Princeton University, which has long recognized SSL’s potential benefits. Among the findings: • Installing 41 new LED luminaires in two parking lots undergoing renovation in 2014 showed that grouping luminaires into zones by means […]
The DLC has announced Version 1.0 of the Networked Lighting Control (NLC) System Specification. This specification and the coinciding Qualified Products List (QPL) for Networked Lighting Controls will provide a valuable new resource to the lighting market, utilities and energy efficiency programs to understand, evaluate and compare Networked Lighting Control Systems. The NLC QPL will […]
In this video by Philips Lighting, part of an education series, Dan Blitzer explains lighting controls and their benefits.
Lighting industry journalist Craig DiLouie recently interviewed Ethan Biery, Design and Development Leader, Lutron Electronics for an article about controlling LEDs for an article in tED Magazine. The interview follows. DiLouie: How are LED sources different from traditional sources in terms of their controllability and their behavior? Biery: As a light source, LEDs are easy […]
The National Electrical Manufacturers Association (NEMA) published NEMA SSL 7A-2015 Phase-Cut Dimming for Solid State Lighting—Basic Compatibility. This standard provides compatibility requirements when a forward phase-cut dimmer is combined with one or more dimmable light-emitting diode (LED) light engines (LLEs). An LLE, for the purposes of this document, comprises one or more LED modules, LED […]
About two-thirds (64%) of the United States is covered by prescriptive lighting rebates, according to BriteSwitch, a rebate fulfillment company. These rebates can significantly reduce the installed cost of new lighting in existing buildings and improve payback by 20-25%, which would reduce a two-year payback to about 1.5 years. Rebates became popular in the 1990s […]
Below is an interview LCA’s education director, Craig DiLouie, conducted with Mick Wilcox, Vice President of Strategic Marketing, Acuity Brands on the topic of lighting and and the Internet of Things. DiLouie: How do you see lighting fitting into the Industrial Internet of Things (IIoT)? Wilcox: Lighting, once relegated to a service, is rising to […]
ARCHITECTURAL LIGHTING recently published an article by Clay Risen, “Seeking Compatibility in the LED Era,” that begins: The transition from conventional to solid-state lighting components is still far from plug-and-play—and the lack of universal standards is not helping. Read it here.
Ethan Biery, LED Engineering Leader, Lutron Electronics, recently contributed a very good article to LEDs Magazine about the current struggle to establish good metrics to characterize flicker. From the article: The evolution of LEDs in the lighting market has not always been smooth, but the technology has come a long way since the early days. […]
The Northwest Lighting Network recently published an article about the potential of luminaire-integrated lighting controls. From the article: While traditional lighting control strategies can yield considerable benefits, Luminaire Level Lighting Controls (LLLC) show promise of both easier installation and commissioning and deeper energy savings beyond other lighting controls. And: The Design Lights Consortium will publish […]
