  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, [...]

On March 13th, U.S. EPA’s ENERGY STAR program issued a memo with final decisions about sunsetting of the ENERGY STAR lighting programs. 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 [...]

At LEDucation, it was encouraging to see the advancements in fiber optic lighting. A company called Universal Fiber Optic Lighting USA (UFO) exemplified this maturing of fiber optic lighting, including the adoption of LED illuminators / light sources, attractive side-emitting fibers, and attractive end fittings, including European crystal. Perhaps what was most impressive was the [...]

One week ago, on March 14th, the California Energy Commission (CEC) voted to repeal portable luminaires from the scope of Title 20 appliance efficiency regulations. Portable luminaires include floor lamps, table lamps, desk lampand other luminaires with a wall plug rather than a hardwired power source. Although CA Title 20 provided a number of paths [...]

Another fun find at LEDucation was a set of LED projectors with dual gobos that spin in opposite directions, creating the effects of moving water and moving fire. The company is Rosco. The X-Effects LED Projectors can achieve a variety of different lighting effects by changing gobos or adding color into either the Static Gobo/Filter [...]
