Who do you think would know these answers other than your co-tantalk poster D. Smith?
So ask in "his" forum...
Did you look at the IST article mentioned in "reflected UV" thread? It shows amount of visible vs UV. You have to add up the mW under curves from 280-400 and compare that to area under 401-435.
Since the graph isn't big enough for you to do that, either contact the author (Wolff), or ask your co-poster to show spectroradiometer breakdown from UV-Visible-IR bandwidths.
As for blacklights, they don't put out enuf visible to "see" bed controls thru eyewear. And last time I metered one it was very low UV output compared to sun or tan lamps.
