Ask Schott how much B2O3 it contains, it has to be a glass that has almost none in it or it would block UV
such glass composition is called quartz not borosilicate
I would like to know how light sterilizers kill the germs hidden in cracks and crevices.
Seriously.
Seems like they are marginally OK for countertops.
Food, no, clothes, no, skin, no,
mouth/nose - double no, plus harmful
plus even if there are no cracks etc, how do you know you are exposing the right amount to kill the bad germies - on every square mm?
seems like clorox would work better
plus not blind or sun burn you.
I asked the same question (eh: more or less) in the other thread (S43 UV-C).
Why do we need this kind of light/emitters?
1/ is it the latest fad, so get it while it’s still fresh?
2/ as a germaphobe you can desinfect your hands until you get a severe skincancer?
3/ to explore/find magnificent things in nature that UV-A can’t reveal (if so: what?)
Rocks, same as a few others. Its for my brother who is the rock expert so I don't know which minerals will fluoresce more with UVC but there can be a big difference compared to UVA. Rock nuts are very much like flashlight nuts - always looking for something better.
To be honest yes. I am all the time with my troath dry because of all the lysol people are using everywhere I go. Also I use hand sanitizer and wash my hands all the times and my hands are super dry because of that.
The skin is one of our best barriers against threats. OCD hand washing weakens that skin.
More important is to NOT pick your nose, rub your eyes, or fiddle with your mustache.
