Black Lights

Although black lights are actually dark purple, much of the light they emit isn't visible to the human eye. Black light bulbs emit light in the ultraviolet spectrum. While this doesn't do much to brighten your surroundings, it does cause the color white, as well as UV ink and many fluorescent colors, to glow brightly. This reaction that black lights cause has many beneficial uses. For example, many countries add a fluorescent strip to paper money to help identify counterfeit bills, while a fluorescent dye is often used to dust for fingerprints, which will then stand out after being illuminated by black light lights. Whatever your use, 1000bulbs.com has the black lights to meet your needs.
