Ive never tested them, no, sorry. But if you could snag a free one off the council like Tim suggested and test it out on an index card or a joker, then you'd be no worse off. If its the watery stuff I mentioned though, that glows extremely bright, but did take thirty seconds or so to set, so thats probably useless for you.
Hope it works out with a cheap/free pen though, if you find out, let us know, could save a bundle on UV effects.
