Wow, this has all been very helpful! Thank you all very much for your help! I also forgot to pose another question. What would be the optimal amount of exposure to be safe? I would think no more than a couple of hours. Also, what about long term. If I’m going to be doing this on a regular basis for the foreseeable future, what would be the effects from years of using the uv light?
When talking about blue light I was referring to what was mentioned by twan3253
I think I looked at his message wrong. I guess that when he was talking about blue light, I lumped it with uv light.
