Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy The U.S. Department of Energy (DOE) recently released a GATEWAY report on a parking-garage demonstration conducted at U.S. Department of Labor (DOL) headquarters in Washington, DC, which serves as a classic illustration of the savings […]
The Lighting Controls Association is pleased to announce that EE300: Lighting Control of LEDs, one of the Association’s popular online Education Express distance education courses, has been completely revised. Residing here, Education Express provides in-depth education about lighting control and controllable ballast technology, application, system design and commissioning, as well as meta-issues such as commissioning, […]
Intelligent, controllable LED lamps offer a new paradigm for home lighting control. Julie Jacobson, editor of ELECTRONIC HOUSE, analyzes the pros and cons of 13 products implementing WiFi/Internet of Things, 6LoWPAN, ZigBee, Z-Wave and Bluetooth. Read it here.
At the Department of Energy’s 10th Annual SSL R&D Workshop in Long Beach, California, nearly 250 attendees discussed the next great leap forward in performance of LED systems. In his February 8, 2013 SSL Postings, “Some Thoughts on the Long Beach R&D Workshop,” DOE SSL Program Manager Jim Brodrick related an interesting statement by Susanne […]
Guest post by Jim Brodrick, U.S. Department of Energy There’s a great deal of interest these days in occupancy sensors as a way to save energy in outdoor commercial lighting applications. Done right, they can increase the energy savings from a lighting system that’s already efficient – such as one based on LEDs, whose inherent […]
EC&M has published an article about trends in lighting control, noting occupancy-based shutoff and daylight harvesting and then focusing on LED control, including wireless options. Read it here.
On Wednesday, April 11, 2012, at 2 p.m. EDT, ELECTRICAL CONTRACTOR Magazine hosted a webinar, in partnership with Leviton, on the three main causes for compatibility issues when pairing energy-efficient lamps with dimmers designed for incandescent technology. On hand to speak about the issue was Craig DiLouie, ELECTRICAL CONTRACTOR’s lighting columnist and acting education director […]
Lithonia Lighting’s Dave Ranieri penned an excellent short article on the potential of matching state-of-the-art lighting control with LED technology. He writes: “When paired with well-designed and integrated digital components, LED lighting systems are fully capable of executing common lighting control strategies, such as manual dimming, scheduling, occupancy sensing, and daylight harvesting. Moreover, the solid-state […]
Designing LED replacement lamps that are compatible with residential dimmers is complex given the diversity in product performance, creating a challenge for manufacturers to design lamps compatibel with a wide range of dimmers. On behalf of ASSIST, the Lighting Research Center investigated dimming performance of a range of LED replacement lamps, CFLs and incandescent lamps […]
by Jim Brodrick, Department of Energy As more and more LED lighting products have come onto the market, one issue that has generated considerable confusion is dimmability. As discrete devices, LEDs are fully dimmable, and as a result the technology has long been touted as being more suitable for dimming than other lighting technologies. Many […]
