LED + SSL

Arguably, the biggest gap in LED metrics is a product lifetime metric and test procedure. Currently, the industry is rife with fraudulent emitter life claims used as LED system product life claims (lamps, luminaires, and engines).

The U.S. Department of Energy (DOE) Building Technologies Office (BTO), within the Office of Energy Efficiency and Renewable Energy (EERE), has published two new reports, 2022 DOE SSL Manufacturing Status & Opportunities and  Solid-State Lighting R&D Opportunities.

Researchers have discovered a new method of generating long-wavelength (red, orange, and yellow) light through the use of intrinsic defects in semiconducting materials, with potential applications as direct light emitters in commercial light sources and displays.

My contribution to the October issue of ELECTRICAL CONTRACTOR talks about LED product warranties and the National Lighting Bureau’s recently launched Trusted Warranty Program.

While rebates for commercial lighting have been around since the 1980s, rebates for LEDs specifically didn’t see widespread acceptance until 2011. Now, 10 years later, we can take an in-depth look at LED rebates and the marketplace.

Are you aware of the Million LED Challenge in California? This program is a collaborative effort by the University of California, California State University, California Community Colleges, and the California State Department of General Services. It recently expanded to include options for converting linear fluorescent lighting to LED.

A study funded by the U.S. Department of Energy (DOE) estimates the energy savings opportunity associated with advanced lighting research conducted by Pacific Northwest National Laboratory (PNNL) related to glare, flicker, color rendering, non-visual effects of lighting, and outdoor environmental effects of lighting.

Join the U.S. Department of Energy and the Illuminating Engineering Society at the 18th annual Lighting R&D Workshop, February 1–4, 2021, where top lighting scientists and industry thought leaders will gather to share progress, challenges, ideas, and solutions to shape the future of lighting. The 2021 workshop will be virtual and free to attend.

The U.S. Department of Energy (DOE) recently released a study investigating age-related changes in LED device efficiency and optical performance.
