UV-C Lighting: How Effective is it on COVID-19 and other Viruses?

For decades, the world has been harnessing ultraviolet (UV) light as a tool. Its power to sterilize has made it essential to the drinking water of billions of people. Research laboratories operate powerful UV lights to clean germs from sensitive equipment. Hospitals and medical facilities use UV light to disinfect and decontaminate surfaces and implements.
