The Illuminating Engineering Society (IES) released a report on germicidal ultraviolet (GUV) lighting's potential to reduce the spread of COVID-19.

Germicidal UV-C light is commonly used to inactivate or kill microbes on surfaces, in air, and in water. When implemented properly, UV-C lighting can kill up to 99.9% of pathogens.

The IES's statement is meant to present a united front on GUV lighting's disinfection capabilities against COVID-19 since the pandemic has sparked so much interest in the lighting, and subsequent conflicting and unsubstantiated claims both for and against the efficacy have been released in a flurry.

The takeaway: 

"Germicidal UV can successfully and safely be deployed to disinfect air in occupied hospital spaces such as waiting rooms, intensive care units and operating rooms. In unoccupied controlled-access environments, germicidal UV can be used as a supplemental measure to disinfect room surfaces, to reduce the spread of healthcare associated infections. Germicidal UV is also being applied for disinfection of some personal protective equipment (PPE) for limited reuse during the pandemic."IES germicidal lighting report

The IES released the report to be helpful and to protect front line medical workers, and it's available as a free download on their site.
