  A Penn State University study published in Leukos has examined how U.S. museum lighting professionals are actually using modern lighting technologies, especially LEDs, and how they choose lighting based on conservation, appearance, and standards. The study creates a current, practice-based snapshot showing that LED adoption is now widespread, but guidance is still applied unevenly [...]

  An interesting article in US Lighting Trends compares the economics of diesel vs. solar construction site light towers. The article argues that while diesel light towers remain the familiar default for construction jobsites, solar-powered area lighting is becoming a more compelling option as owners and contractors prioritize lower emissions, quiet operation, and long-term cost [...]

  SB 3037, the Dark Sky Act, is currently working its way through the Illinois legislature. The bill sets out to add dark sky requirements within the Illinois Stretch Energy Code. It would update the Illinois Stretch Energy Code requirements so that the Code contains separate residential and commercial components. It specifically proposes: (A) outdoor [...]

  This is my latest article published in the March 2026 issue of LD+A. The Stack is rooted in theatrical design principles Rising above Vancouver’s skyline, The Stack at 1133 Melville Street is more than an office tower—it’s a statement in sustainable architecture and lighting design. As Canada’s tallest zero-carbon building, its sculptural form and [...]

  Alloy LED’s Radialux 5.5 COB RGBTW Tape Light represents an innovative convergence of RGBTW with COB tape. This five-channel tape light integrates dynamic RGB color-changing with tunable white light ranging from 2700K to 6500K, all within a non-pixilated Chip-on-Board (COB) construction. The result is a smooth, uninterrupted line of illumination for better looking architectural [...]

  Nichia reports that a joint study with the Tokushima Agriculture, Forestry and Fisheries Technology Support Center found Nichia’s HPS color LED at 1800K (amber) had the lowest insect attraction among the tested light sources. The company says the result came from both laboratory and outdoor evaluations comparing LEDs with different correlated color temperatures (CCTs). [...]

  Stanford researchers are designing domestic robots to help older adults age in place with more safety, mobility, and independence. These robots are support tools rather than replacements for human caregivers. The robots could reduce the strain on families and care systems as the U.S. population grows older. The article highlights several use cases: helping [...]

  A recent New York Magazine article describes a noticeable shift in New York City apartments toward orange, amber, and red-tinted lighting, driven by a mix of aesthetics, mood, and the flexibility of smart LED lamps. The trend is more than a passing design quirk: residents, designers, and lighting consultants are intentionally choosing ultra-warm light [...]

  The FCC has voted unanimously proposing to bar Chinese and Hong Kong testing labs from certifying electronics for sale in the U.S., expanding an earlier restriction aimed at labs tied to the Chinese government and other national-security risks. The move is meant to reduce the chance that insecure or compromised devices enter the U.S. [...]
