It's a bit incorrect to state that UV LEDs or Lights are not dangerous. In comparison to something else, yes, they may not be as dangerous but they are definitely not harmless. It's akin to radation. Low levels of radiation still have the potential to cause damage, but not nearly as much as highly active radioactive materials. I own samples of throrium metal, uranium metal, and various other radioactive items. The levels they emit are very low and not dangerous, but I still take precautions and don't expose myself to them for extended periods of time. This is because even though the radiation is of a low level, it is still above zero which means it still poses a problem.
To ignore the dangerous of UV Light will simply cause many problems down the line. There's a reson why UV light makes certain items glow or look different. It's because of the immense energy the light has. If it wasn't that energetic, the items wouldn't glow. So if you think that a simple bulb will protect you from the damaging effects, look and see if the sensitive items in your room are glowing. If they are, then the bulb isn't doing anything.
There's no problem having UV light in your cab or in your gameroom, but just pay attention to how much of it you have and how much time you spend in there. The less exposure the better.
