  The IES is now accepting submissions for the 2026 IES Industry Progress Report. The IES is seeking significant new advancements in lighting products, research, publications, and design tools from the past year. The mission of the Progress Committee is to keep in touch with developments in the art and science of lighting throughout the [...]

  California’s SB 343 law creates a new “accurate recycling labels” framework meant to reduce misleading recycling claims and make packaging labels better reflect what is actually recycled in the state. The core idea is that companies can’t use the chasing arrows symbol, or any other recyclability indicator, unless certain criteria are met, and those [...]

  LightNOW has already written about Maine’s new strict dark sky law, and Hawaii’s proposed dark sky bill. Here is a look at New York State’s proposed dark sky law. New York State’s proposed Dark Skies Protection Act (Assembly Bill A4615 / Senate Bill S5007) is part of a broader effort to reduce light pollution, [...]

  Recent horticultural lighting trends are centered on smarter LED systems, more precise spectral control, and tighter integration with greenhouse automation. The biggest shift is away from static lighting toward dynamic, data-driven lighting that can adjust intensity and spectrum in real time based on crop stage, natural sunlight, energy prices, and climate conditions. LED Becomes [...]

  The Association for Smarter Homes & Buildings (ASHB) surveyed 308 building owners, operators, IT leaders, and facility managers, in the US and Canada, about trends in smart buildings. The results are in ASHB’s report, 2025 Smart Building Trends & Technology Adoption. The document’s key finding is that smart building technology has moved from experimentation [...]

  On April 1st, I published an article about the furniture industry’s declining imports and exports in 2025 relative to 2024. This likely indicated an overall decline in the furniture market, due to new 2025 US tariffs. I raised the question of whether similar declines occurred in the US lighting industry. After a little research, [...]

  Zumtobel, in Europe, has launched the first remanufacturing service by a luminaire manufacturer. The new standardized remanufacturing service extends the life of lighting systems to at least two product life cycles. The full-service, turnkey package covers everything from deinstallation and remanufacturing to reinstallation. The as-new remanufactured system will provide at least equivalent performance, as [...]

  Design Lights Consortium (DLC) has announced the DLC Summit 2026. It will be held October 26-27, 2026, in Los Angeles, CA. The conference is co-hosted by the Los Angeles Department of Water and Power (LADWP). The theme of the summit is “Next Gen Lighting: Controls, Integration, and the Environment.” The agenda will include integrating [...]

  A recent dark sky project has had me thinking and researching light pollution, sky glow, and by extension an optical phenomenon that we can experience on most clear days or nights. Rayleigh scattering is an interaction of light with Earth’s atmosphere. It’s most notable characteristic is it scatters lower wavelength light colors (violet and [...]
