Title: Great Urine Detector, Bad Uranium Checker
Review: I ordered this UV light both as a way of spotting where my 15 year old cat was piddling and also to check vaseline glass for uranium content. It works fine for spotting urine stains, but doesn't seem to work so well on glass. Maybe it was just the way I was using it, but it seems to only highlight specific spots on the glass rather than give it a nice, even, all-over glow that you need for photographing. I think the style of UV lights with the long tube would work better for that purpose than the flashlight style.Still, it does do a great job of lighting up urine stains, so if that's what you're looking for then this would be a good choice.
