This sounds like an episode of The Big Bang Theory, 'How to find the science woman with the beads".

Anyway, just reporting back, no word from that UK place that has the UV blocked longpass filters. I will write them again, but if a place won't answer their emails, then how do they sell things?

Interesting, I cannot recall them glowing in the dark, but then it was before I got my UV torches, so I was not focused on that aspect.
