We have all seen the wide range of new products claiming to be effective against pathogens of all sorts. Common claims range from the rather ambiguous “fights germs” to the more specific but questionable claim “can disinfect up to 40 square meters of the surface at a time.” Maybe it’s just the times we’re living in, but my first reaction is to take a very skeptical view of these claims. It also seems that I’m not the only one. My neighbor, who is not in the lighting field, asked me if I thought “these UV lights” are safe. Almost without taking another breath he followed it up by asking “… do they actually work?”
