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).

Education + Resources, LED + SSL
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.
