The Beauty And Disruption Of Rayleigh Scattering

  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 [...]

Case Study: Tariffs Shrink Furniture Imports & Exports

  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 [...]

Networked Lighting Controls Increasing Size Of J-Boxes

  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, [...]

The Trend Toward Low Glare Industrial High Bays

  There is a strong, growing trend toward low-glare high bay fixtures in industrial applications, particularly as facilities increasingly adopt automation, robotics, and machine vision systems. The shift is driven by the need to optimize lighting for both human worker well-being and the technical requirements of automated equipment, which requires consistent, shadow-free, and glare-free environments to operate [...]
