‘"Ultraviolet light in general has been used to kill bacteria and viruses for a very long time," David Brenner, director at the Columbia University Center for Radiological Research, told USA today. It's been known to kill bacteria and viruses for the last century and for the last two to three decades has been used to disinfect surgical theaters or hospital wards. "It's being used in the MTA here in New York, in the wee hours between 1 a.m. and 5 a.m. when the MTA is closed down," he added, referencing the Metropolitan Transportation Authority public transit vehicles and some fixed locations being sanitized with UV light. "It’s been in use to kill viruses and sterilize locations when people aren’t around, which is not ideal because even if you have a sterilized location at 9 o’clock in the morning and people start coming in, they’re potentially gong to contaminate".’

Now there’s research to support the theory.
The study shows that roughly 40 millijoules or less are needed in a matter of minutes for the virus to be inactivated. Meaning a high concentration amount of UV produced through a lamp can be as effective and much faster versus hours and hours of sunlight.’
