Lazy question What big an area can one $500 UVC cover? Do those 4 in the dance room genuinely clean the whole area?
Surely to be actually mass-practical we need one that can just be a lightbulb and attach to a regular fitting? Obviously it must be harder than all that,,,,
How big an area they cover depends on how long the sight lines are: the more air the light can travel through the more it can clean. It’s not linear, though, and there are different effects for different pathogens because some are quickly inactivated with low levels of UVC and others need more. The modeling tool Illuminate can be very useful here; here’s something I wrote up when I was figuring out what made sense for the dance hall: Assessing Far UVC Positioning.
