Could someone have used uv-c black lights thinking they looked cool and not realising about the severe health hazards?

- bertil 3y agoYes, and it’s apparently not the first time it happens in Hong-Kong. Easy access to electronics, no real control.

- seanp2k2 3y agooof, yeah those were powerful UV-C disinfecting bulbs. I've got half a dozen Elektralite eyeBall UV fixtures that I use for parties in conjunction with other lights, which are 18x3w 385nm UV LEDs per fixture. I don't stare directly into them as they're pretty intense, but they're still firmly in UV-A territory and don't hurt your eyes. They do light up anything fluorescent super bright though! - UVA (315-400 nanometers) - UVB (280-315 nanometers) - UVC (180-280 nanometers)
- anon84873628 3y agoSince you are familiar with the topic: So now when I go to a place with blacklights, how do I know someone didn't get confused (or is just ignorant) and used bulbs that can burn my eyes? Thanks.
- kayfox 3y agoIf the blacklights are LEDs they are UV-A and safe. UV-C LEDs exist, but they are so expensive noone would make a stage lighting fixture out of them. If they are fluorescent tubes that look kinda purple, black or really deep blue when off, they are UV-A and safe. These tubes use a phosphor to convert UV-C light to UV-A light and are made of wood's glass to filter out all but that UV-A light. If they are fluorescent tubes that are clear, they are UV-C and unsafe. Theres a third type that uses phosphor and regular glass that emits UV-A and some white light, but those are almost never seen in stage lighting fixtures. There are also UV-A arc lamps like the Wildfire IronArc series, which are safe as long as they have the dark purple wood's glass filter installed on them (these lamps do not ship without such a filter, but sometimes you encounter used ones that the filter was broken in or otherwise removed).
- RenThraysk 3y agoAn ozone smell can be an indicator. UVC will break O2 into two Oxygen atoms, which then combine with other O2 to form O3, ozone.
- Wistar 3y agoExactly what I was thinking. UV-C.
- klyrs 3y agoReplace "uv-c black lights" with "radium paint" and it doesn't change the answer: yeah somebody could have done just that.
