I wrote this news piece for the May issue of tED Magazine. Reprinted with permission. The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute recently released a circadian stimulus (CS) calculator. Based on the CS metric, this tool can aid lighting professionals to select light sources and light levels that will increase the potential for [...]

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has recently released a free open-access circadian stimulus (CS) calculator to help lighting professionals select light sources and light levels that will increase the potential for circadian-effective light exposure in architectural spaces, utilizing the CS metric. Developed by LRC researchers, the CS metric is a new [...]

The Illuminating Engineering Society has announced a call for speakers for the Society’s 2016 Annual Conference to be held from October 23 – 25 in Orlando, Florida at the Hyatt Regency Grand Cypress Hotel.

By Bill Chan, President, LiteController Inc. Melanopic Equivalent Daylight Illuminance (M-EDI) is widely used to assess circadian-effective lighting, but is it truly optimized for human biological responses? What is M-EDI? Melanopic Equivalent Daylight Illuminance (M-EDI) is a metric used to evaluate how light impacts our circadian rhythms, based on the sensitivity of Melanopsin, a photopigment [...]

  A recent article, Guidelines for Converting LED to LED: What Turnkey Lighting Contractors Need to Know, by George McIntyre, addresses the emerging need for second-generation LED retrofits in commercial and industrial buildings. As many first-generation LED systems installed between 2015 and 2020 begin to show signs of decline, lighting contractors should approach LED-to-LED conversions [...]

  Osteo-odonto-keratoprosthesis (OOKP), commonly referred to as “tooth-in-eye” surgery, is a remarkable and complex surgical procedure designed to restore vision in patients who are blind due to severe corneal damage, particularly when all other treatments have failed. Developed over 60 years ago by Italian ophthalmic surgeon Benedetto Strampelli, OOKP is now performed in select centers [...]

By Derek Bobbitt and Geoff Ling, Merrimack Group The first 100 days of the new U.S. administration have been tumultuous to say the least. The tariff war has caused major disruption to supply chains, caused significant stock market volatility, and stoked fears of inflation and recession. For lighting business owners, this environment has introduced a [...]

  A federal judge has ordered the Trump administration to immediately reinstate funding previously awarded under the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA), after President Trump froze these disbursements on his first day back in office. The ruling, delivered by Judge Mary McElroy of the U.S. District Court for [...]

  In a groundbreaking study, scientists at the University of California, Berkeley, have developed a technique called “Oz” that allows the human eye to perceive a brand-new color, which they have named “olo.” This color is described as a blue-green or teal of unprecedented saturation-far more vivid than any color found naturally or previously seen [...]
