I bought one of these the other day. It says scorpion finder on it. I know
scorpions fluoresce, and when the weather gets warmer, this place is full of
them. Other uses are listed, one of them antique analysis. Does anyone
have one of these, and what do you use yours for? What do professional
contractors use them for?

And just for the netnannies, I know the light isn't actually black, but
rather UV, and "black light" is just an inaccurate term.

Some aquarium lamps are black lights. It causes some fish to glow at
night.

Also the lights can be used in evidence tampering cases. A dust is
used and anyone that touched the evidence will have glowing
fingers....

I still have a 12 V boat battery powered light about the size of a
small aquarium light. It has a shield covering the bulb. I used it
when fishing at night. Some fishing lines (Stren) will glow at night
so you can see the line.

Night clubs used them to detect stamps so you can leave / enter the
club more than once by showing the stamp under the light.
