Now, why do they call these a black light?
Ever felt the need to take a really good long look at your surroundings and see what you can't see?
You know, imperfections in the paint job on your walls, minute scratches on your car, if that rather unpleasant smell in your kitchen was an unwelcome gift from your pet dog.
Or maybe you just want to see the world burn?
Well if it's the latter, then you should seek some help, but if it's any of the former, or you just want to see something funky, then you might want to look at a UV blacklight, just like this one.
