  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 [...]

  Japanese home builders are rapidly expanding their footprint in the United States, reshaping the landscape of the American housing market through a wave of acquisitions. Since 2020, Japanese firms have acquired 23 U.S. single-family construction companies—more than doubling their pace from previous years. This surge reflects both strategic ambition and economic necessity, as demographic [...]

  Natural Resources Canada (NRCan) has adopted new General Service Lamp (GSL) regulations that will largely harmonize with the current US GSL requirement of 45 lumens per watt minimum. Timing Manufactured on or after January 1st, 2026 for general service incandescent lamps or a general service incandescent reflector lamps. Manufactured on or after January 1st, [...]

  Design Lights Consortium (DLC) has released the Networked Lighting Controls (NLC) Requirements V5.2 Draft 1. DLC laid out four goals for Version 5.2: Highlighting emerging capabilities in networked lighting controls. Present new system capabilities, particularly integrations with thermostats to save energy and improve building performance. Strengthening the role of NLC in energy efficiency programs [...]

  InSinkErator, one of the leading manufacturers of garbage disposals, has released its LEDefense line, with antimicrobial light technology added to garbage disposals to fight the odor-causing bacteria that builds up with food waste. Instead of waiting until a disposal smells bad and then using citrus peels or cleaning pods, the product uses always-on light [...]

  The TALQ Consortium’s latest release, version 2.7.0 of the Smart City Protocol, isn’t about any flashy new features, but rather making smart outdoor lighting systems easier to integrate, certify, and scale across vendors. For the lighting industry, the big message is that interoperability is becoming more standardized and more demanding, which should favor manufacturers [...]

  I was recently struck by a pair of articles in Home News Now, about the reduction in furniture imports and exports in 2025 versus 2024. The reductions suggest tariffs are reducing trade flows on both sides of the furniture market: imports fell almost three times more than exports (on a percentage basis), narrowing the [...]

  The increasing complexity of modern lighting control components, such as smart dimmers, sensors, and networked modules, is directly leading to the use of larger junction boxes. The added electronics, extra wiring for communication, and the need for heat dissipation require more volume than traditional electrical components, necessitating deeper or wider boxes: Smart switches, dimmers, [...]
