  Effective January 1, 2023, lamp/bulb manufacturers have new “extended producer responsibility” requirements in Ontario, Canada, for end-of-life management of “lighting” under Ontario Regulation 522/20: Electrical and Electronic Equipment (the “EEE Regulation”). This includes both residential and commercial lamps sold in Ontario. Product Care Recycling is a not-for-profit organization registered as a “Producer Responsibility Organization” [...]

Researchers at the University of Buffalo have published a study demonstrating that light therapy reduces heart disease in mice. If these results hold true in human trials, this could be an extremely important finding. Heart disease is the #1 cause of death in the U.S. One in five Americans dies of heart disease. A simple, [...]

Researchers at the University of Toronto demonstrated a window technology that utilizes multiple layers of plastic sheets that can be filled with different pigments to selectively filter infrared (IR) heat and/or visible light. This approach has the potential to dramatically reduce HVAC energy requirements for buildings. Different layers within the prototype window filter out infrared [...]

Korean micro-LED manufacturer, Lumens, announced in January, the development of R-G-B micro-LEDs grown in a stack, on a single wafer / substrate (aka monolithic). The benefits of this approach include reducing the transfer process by two-thirds, reducing costs, and increasing productivity. The first applications for this technology are the micro-LED display markets, including TV, AR, [...]

Here are the major takeaways from the decision memo: EPA is finalizing the sunset of the ENERGY STAR specifications (programs) for lamps and luminaires, effective December 31, 2024. Recessed downlights and downlight retrofit [...]

Translucent concrete, also known as light-transmitting concrete, is a building material that allows light to pass through it. It is made by embedding optical fibers in a concrete matrix, which allows the material to transmit light while still maintaining its structural integrity. The fibers used in translucent concrete are typically made of glass or plastic [...]
