Most of what we see from a black light is the effect it has by making things such as our shirts and teeth glow. The light emitted by black lights is mostly UV, which is invisible to the human eye.
Phosphors convert the energy from UV radiation in black lights into a small amount of light we can see. What we see glowing under black lights are phosphors, which is any substance emitting visible light when responding to radiation. Black lights can also be used to authenticate artwork or test counterfeit bills. Restaurants and grocery stores use black lights for insect protection, and forensic scientists use them for crime scene analysis. However, they aren’t just for show, they have many functional uses as well. We often see black lights in bowling alleys, amusement parks, clubs, for Halloween displays, and in other fun locations.

A true black light emits more visible light than a black light-blue bulb. The rest of what the bulb emits is ultraviolet light in UVA form, which makes fluorescent colors glow but is not seen by the human eye. A black light-blue bulb keeps almost all visible light inside the bulb so only a slight purple glow is emitted.
