National Academy of Sciences Releases Report on Solid-State Lighting

The National Academy of Sciences, Engineering, and Medicine (NAS) has published a report, Assessment of Solid-State Lighting, Phase Two, which is a follow-up to its 2013 report. The new report focuses on three key areas: commercialization (noting the rapid uptake of SSL since the 2013 report), technology development (updating the findings of the 2013 report), […]

New Report Published on Color Shift Impact on Reliability

An industry working group facilitated by with the Department of Energy has published a new report on the impact of color shift on reliability. LED Luminaire Reliability: Impact of Color Shift was written to provide a better understanding of how and why color shifts. It does not define limits for specific applications. Developed by the […]

DOE Publishes LIGHTFAIR International Presentations

At LIGHTFAIR 2017 in Philadelphia, DOE once again hosted an informational booth that offered free educational sessions to attendees. DOE has now made these presentations available for free download. They include: Connected Lighting Systems Efforts Michael Poplawski, PNNL NGLS Competition One: Installation and Configuration Evaluations Ruth Taylor, PNNL There’s Something About Red: Applying TM-30 in […]

Acuity’s Dan Ryan on Bundling in Lighting Industry

I recently had the pleasure of interviewing Dan Ryan, VP Product, IoT Solutions, Acuity Brands Lighting. The topic: disruption in lighting, notably the current trend of “bundling,” which was the subject of his presentation I caught at Strategies in Light. I’m happy to share his responses with you here. The interview informed an article I […]

Cree Canada’s Shirley Coyle’s Response to AMA Outdoor Lighting Guidelines

Shirley Coyle, President of Cree Canada, recently contributed her thoughts to Lighting Design & Application in response to a request to chime in on the American Medical Association’s recent guidelines for LED outdoor lighting. She points out that basing recommendations on correlated color temperature (CCT) is flawed: On the issue of safety, the most obvious […]

2017 DOE SSL R&D Workshop Presentations Posted

Earlier this year, the Department of Energy hosted its 14th annual Solid-State Lighting R&D Workshop. Over three full days, 250 attendees participated in sessions covering LED and OLED technology. Presentations from 60 experts addressed the complex science and technology challenges facing SSL today, as well as innovative new ways to improve manufacturing processes, reduce costs […]

DOE Publishes Report on LED Street Lighting’s Impact on Sky Glow

DOE has published the results of a study of the expected contributions to sky glow from converting high-pressure sodium (HPS) street lighting to broader-spectrum (i.e., white light) sources, with specific focus on LEDs, and presents the contributions in a manner relative to HPS baseline conditions. These conditions represent typical conversions in the U.S. and include […]

Jim Brodrick on the DOE’s 14th Annual SSL R&D Workshop

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy Although I recently spent a week at the beach, there was no sand, surf, or bathing suit in sight. That’s because I was in Long Beach, CA, at DOE’s 14th annual Solid-State […]

DOE Publishes CALiPER Snapshot on LED Industrial Luminaires

The U.S. Department of Energy’s CALiPER program has released a new Snapshot Report on LED industrial luminaires, based on DOE’s Lighting Facts database. Key findings: • The efficacy of LED industrial luminaires is notably higher than what’s typical of their incumbent counterparts. About 23% of the industrial luminaires listed with LED Lighting Facts listed products […]

ELECTRICAL CONTRACTOR Article Covers Tunable-White Lighting

My contributions to the February issue of ELECTRICAL CONTRACTOR included an extended feature on tunable-white LED lighting, covering color basics, product types, color quality, control and applications. Check it out here.
