It’s likely because some light fixtures that emit a ton of UV light also look “cool” and get used in the wrong setting. They’re supposed to be for stuff like disinfection. Looks like the bulbs outlining the dj both could be the issue. It wouldn’t be any of the professional fixtures.

Yea I honestly can’t believe people who think of themselves as decent would delight like this in the suffering of others? You realize voicing opinions like this takes you right out of the ‘right side of the argument’ and outs you as a pretty much an awful person? Do better, people.
