A blacklight is a term for those lights that emit, you got it, blacklight! Or to put it simply, they emit UV light that is not visible to the naked eye, hence the term ‘black light’. These come in a variety of shapes and sizes, from blacklight fluorescent tubes to LED bulbs and even mercury-vapor lamps.
Blacklight can make certain materials glow in the dark, by blocking out most of the light from the visible spectrum. You might have seen it being used in clubs and parties, where everybody’s clothes seem to have a strange glow. Or even in museums and aquariums, where certain exhibits seem to glow in the dark. But blacklight fluorescent tubes also have other applications, like verifying the authenticity of banknotes and even authenticating antiques and oil paintings.
