I would imagine that the leaded glass stops pretty much all of that light, since its usually high end intense blue and UV light. The problem is that usually if you are in a position to see the light, you are probably gonna spend some time in the hospital getting flushed with neutron absorbers afterward (such is life, you always pay a price to do the fun stuff....).

I don't know if St. Elmo's fire isn't emitting due to the same phenomena, as the fire is a plasma bottle, the plasma particles are probably moving around at a pretty good clip inside the bottle. I do remember lighting off a makeshift gauss gun at a freinds place in Seattle once, shooting a copper plasma at a concrete wall. It definitely put out a neat glowing beam of short duration as it was fired. A little 1/4" slug of 12 guage copper wire was the projectile source, it blew a 6 inch wide hole in a concrete block wall.... neat stuff.... gotta put one together for home defense purposes.....
