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.

tbf, the post was tech-sub-appropriate, and many people up/downvote on that alone when it comes to whole posts. Me included, it’s just a really solid system, if a little counter-intuitive. Comments are different though. It’s more just like/dislike with comments.
