I got a cheap 60W UVC LED for hopefully killing mold under the house, but when I first saw the bulb, I noticed no glass lenses on it (I got the non ozone version). I also noticed when powered on it didn't look like the right color. I did glance at the bulb from about 40ft, and further observed it's faint reflections from another room to minimize risk. It looks quite blue instead of the purplish greenish blue I've seen from glass UVC tubes. I just now checked, and it seems to be a lighter blue, so maybe it needed to warm up.
Anyway, how can I test that it really is putting out strong UVC? What can I put near it or filter it with to observe definite results of UVC output?
