Light + Health

Mark Halper has an interesting article in LED’s Magazine interviewing Russell Foster, the scientist who predicted the non-visual receptors in the eye that are involved in the circadian response to light (pRGCs / ipRGCs). He says circadian lighting science isn’t ready yet, and there are too many unknowns.

On March 17th, 18 circadian lighting researchers published a “consensus view” of circadian lighting recommendations, titled: Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults, in the journal PLOS Biology. The authors include well-known circadian lighting researchers, George Brainard and Steven Lockley.

Two new studies, one on young children, the other on adults, suggest detrimental health effects of light at night.

While there are a lot of smart wall switches in the market, Orro has innovated by adding automated circadian lighting scheduling with many of the other features that you’d expect from a premium smart switch.

A University of Oregon researcher makes an interesting case for how Luminaire Level Lighting Controls (LLLC) sensors can improve indoor air quality and human health. Over the last year, returning to offices and schools in a pandemic increased awareness of indoor disease transmission, energy consumption, and overall indoor environmental quality.

New technologies are creating novel tools to pursue healthy and sustainable buildings. At the same time, North America is moving toward a post-pandemic, new normal.

Greenheck, a provider of air movement equipment, announced the incorporation of patented Northern Light® UV-C technology into its line of AMPLIFY™ overhead HVLS fans, today.

A study in the UK highlights the critical importance of proper hospital lighting, as well as other healthcare buildings. According to the study, patients who were served in a newly renovated hospital were able to be released a day and a half earlier than those who were served in the old buildings.

Legrand recently announced the publication of research showing its Kenall Indigo‑Clean light disinfection technology effectively and safely inactivates SARS-CoV-2 and influenza A viruses in a range of real-world clinical settings. The study was published in partnership with the Icahn School of Medicine at Mount Sinai.
