black lights
Glow-revealing fixtures
Black lights are lamps that emit ultraviolet radiation, making certain materials glow while producing little visible light themselves.
They're used to detect substances invisible under normal lighting—bodily fluids at crime scenes, security features on currency, stamps at club entrances.
The purple glow associated with black lights comes from a small amount of visible violet light they also emit.
