Ultraviolet - Wikipedia

A black light lamp emits long-wave UVA radiation and little visible light. Fluorescent black light lamps work similarly to other fluorescent lamps, but use a phosphor on the inner tube surface which emits UVA radiation instead of visible light. Some lamps use a deep-bluish-purple Wood's glassoptical filter that blocks almost all visible light with wavelengths longer than 400 nanometers. Others use plain glass instead of the more expensive Wood's glass, so they appear light-blue to the eye when operating. Inca…
