Works fine
Quality light.
Works well on 2X CR123 or (if they fit) one 18650 - no difference in output.
Not all of my protected 18650 cells fit in this light. I tried 10 cells, and only 3 would go into this light. I don't have the unprotected cells to try. Having to sort cells to find those that fit is a nuisance.
You should have some use in mind for a black light when you buy this light. Its just a toy.
It is fun to play with, look at various things, see what glows brightly in the dark, look at women's hair and see it glow weird when they color it, and look at various paper currency.
