  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, [...]
