Are there simple ways to test whether a light is likely short wave / UV-C, or at least whether it is probably a fake?
Real Example: 2 lights are allegedly germicidal and supposedly emit germicidal 254nm radiation.
- Light 1 darkens transition glasses and emits the smell of chlorine / ozone.
- Light 2 does neither but appears much brighter than Light 1.
Does the ozone smell of Light 1 entail that it at least emits radiation within the UVC band?
Assuming the glasses do darken outdoors and do darken in response to Light 1, given that they do not darken with Light 2, is it safe to conclude Light 2 emits no UV at all?
