The growing understanding of the relationship between light and health has fueled a new lighting trend in circadian-supportive lighting. Some lighting professionals are embracing it while others are taking a wait-and-see approach. While there may be debate about implementation, there is widespread agreement that sufficient light falling on the eye for an adequate amount of time during the day is supportive of circadian health. The question now is should practitioners wait for more research, or should they begin implementing circadian-supportive lighting strategies based on what is known today?

Sunlight Is Not Proven to Kill COVID-19
Dr. Greg Murphy, a Republican Congressman from North Carolina, recently said sunlight can kill the novel coronavirus, but experts say the sun’s UV emission that reaches the earth’s surface isn’t enough to prove out as a disinfectant.
IES Releases Free Report on Germicidal Ultraviolet (GUV) and COVID-19
In response to the COVID-19 pandemic and a wave of seemingly conflicting statements and opinions about the disinfection capabilities and safety of GUV, the Illuminating Engineering Society has issued a report by their Photobiology Committee explaining germicidal ultraviolet (GUV) disinfection and its potential to safely reduce the transmission of SARS-CoV-2, the virus that causes COVID-19.
NLB Interviews LRC about UV Light and COVID-19
National Lighting Bureau executive director and EdisonReport editor Randy Reid interviewed Dr. Mark Rea of the Lighting Research Center to talk about UV lighting applications for COVID-19.
How to Sleep Better During Self-Isolation Using Light
The Lighting Research Center (LRC) has released a new video on how to maintain good sleep while working from home or quarantining indoors.
CIE Offers Two Free Publications on UV Disinfection
Supporting the global action to reduce the transmission of COVID-19, the International Commission on Illumination (CIE) recently released two key publications on ultraviolet radiation disinfection, now available free.
IALD Launches New Guidelines for Manufacturers for WELL Rating Systems
In collaboration with the International WELL Building Institute (IWBI), the International Association of Lighting Designers (IALD) has launched guidelines for lighting manufacturers to help lighting designers more easily determine if their designs meet the WELL Building Standard criteria. The WELL v2™ pilot is the latest version of the WELL Building Standard, a rating system that focuses exclusively on the way that buildings and everything in them—including lighting—can improve our comfort and enhance our health and wellness.
