  Inclusive lighting design is a holistic approach that aims to create illuminated environments accessible and comfortable for everyone, regardless of age, ability, or background. This approach goes beyond meeting basic standards, focusing instead on addressing the unique needs of diverse individuals to enhance their daily experiences and overall well-being. Key Principles of Inclusive Lighting [...]

  The DesignLights Consortium (DLC) has released their Draft 1 Horticultural Technical Requirements V4.0. The draft proposes three updates:  Efficacy increase: Hort V4.0 proposes to increase the efficacy threshold to 2.5 μmol × J-1, which is an 8.7% increase over the Hort V3.0 threshold. This will set the DLC efficacy threshold for LED-based horticultural lighting at more [...]

  Ten states and Canada have passed laws banning most fluorescent lamps from being sold. The effective date (start date) for many of these fluorescent bans is January 1, 2025, in just a couple days. These states include: California: CFL pin-base & linear fluorescent effective 1/1/25. CFL screw-base already active. Colorado: CFL screw-base, CFL pin-base, [...]

The Smart Surfaces Coalition has launched a peer learning network to help cities increase climate resilience through “smart surfaces” infrastructure. This initiative, announced on Monday, aims to connect city staff and provide them with valuable resources to implement climate-resilient solutions. Smart surfaces, as defined by the coalition, include reflective, porous, and green urban surfaces, as [...]

  IBM has unveiled groundbreaking research in optics technology that could revolutionize how data centers train and run generative AI models, using light instead of electricity. The company’s co-packaged optics (CPO) innovation aims to replace electrical interconnects in data centers, offering significant improvements in speed and energy efficiency for AI and other computing applications. IBM [...]

  The DOE’s new CALiPER testing report on upper-room Germicidal Ultraviolet (GUV) luminaires highlights significant advancements and persistent challenges in this technology. Upper-room GUV, recommended by both ASHRAE and the CDC, has shown promise in delivering substantial energy savings while meeting ASHRAE Standard 241 and CDC ventilation targets without requiring major HVAC upgrades. Key findings [...]
