I've never encountered lights that don't have UV filters in them.
There's no way to control the UV filter via DMX/Artnet/sACN. It's a fixed dichroic filter in front of the discharge lamp. It's an extremely cheap filter, as well, so I doubt it would be excluded from cheapo knock-off brand lights.
Certainly on any light available in the US and EU. It just won't get certified for sale.
Besides which, I haven't used a discharge lamp in years. It's all LED now, even the cheap stuff.
There is no way "set channel 4 to full" would disable any safety features in a moving light that would allow it to output damaging UV light. And the only other way it would hurt someone is if it was focussed on them, and they actively stared into it. Like, staring at the sun kind of level of staring at a light.
So, get rid of that "ordinary stage lights" pish.
This is absolutely a case of "we should get UV lights". And instead of getting safe UV cannons for fun florescent paints, they got UV disinfectant lights. Probably still makes florescent paints glow, but it's the wider band UV stuff designed to kill biological cells (ie disinfect). Which is exactly what it did to people's skin and retina.
