  Surging utility rate cases, accelerating load growth, and eroding public trust are converging into a critical inflection point for the U.S. power sector. In the first quarter of 2026 alone, utilities filed $9.4 billion in rate-hike requests, underscoring the scale of capital recovery now flowing through regulatory pipelines. Yet this wave of filings arrives [...]

  A new class of photonic radiative cooling (PRC) coatings is advancing from laboratory research into viable commercial products, offering a passive pathway to reduce building heat loads without electricity. These coatings are engineered to reflect the vast majority of incoming solar radiation while simultaneously emitting heat through the Earth’s atmospheric window, enabling surfaces to [...]

  Signify in Europe expanded its circular lighting portfolio, last year, with the launch of the Philips MASTER LEDtube T8 EM/mains, the first LED tube in Europe to incorporate a significant proportion of post-consumer recycled (PCR) plastic into a mainstream, specification-grade lamp. Engineered for retrofit applications, the product integrates approximately 40% PCR plastic while maintaining [...]

  Scientists at the University of Cambridge have achieved what was once considered impossible by electrically powering insulating nanoparticles to create a completely new kind of LED. Using tiny organic “molecular antennas,” the team found a way to funnel energy into materials that normally cannot conduct electricity, producing ultra pure near infrared light with remarkable [...]

  Collaborative robots, or cobots, are moving from factory novelty to practical production tools, and the lighting industry is well positioned to benefit from that shift. For lighting manufacturers, the biggest implication is not replacement of people, but a rebalancing of labor: cobots can take on repetitive, precise, or ergonomically difficult tasks while skilled workers [...]

  Brand authority now matters as much as or more than traditional keyword-focused SEO because search and AI answer systems increasingly reward recognizable, trusted entities over isolated pages. Authority is a reputation asset built through consistency, expertise, and visible proof across the full digital footprint of a B2B company. In practical terms, brand authority starts [...]

  Here is a look at ten color rendering metrics: CRI / Ra: The most used Color Rendering Index (CRI), is based on averaging the first 8 test colors (R1–R8), out of the 15 tested, reported as a 0–100 score. It is a measure relative to a reference source, either sunlight or an incandescent / [...]

  The American Lighting Association (ALA) put out a government affairs newsletter, last week, summarizing a trio of federal trade actions announced in early June that are poised to reshape cost structures, sourcing strategies, and compliance risk across the lighting and electrical supply chain, with implications extending well beyond metals pricing. At the center is [...]

  “Shadow” is best understood as a lighting-design methodology that intentionally uses shadow as a design material, not as a flaw to eliminate. In practice, it means shaping light so shadows help define form, depth, texture, atmosphere, and emotional tone rather than simply filling everything with uniform brightness. Traditional lighting often tries to reduce shadows. Shadow-based [...]
