blacklights
Glow-revealing fixtures
Blacklights are lamps that emit ultraviolet light, making certain materials glow while producing little visible illumination.
They're used to detect substances invisible under normal light—bodily fluids at crime scenes, security marks on currency, stamps at club entrances.
The purple glow is iconic at parties and in haunted houses, where it makes white clothing and teeth appear to fluoresce.
