A Black light or UV Light is a lamp emitting electromagnetic radiation that is almost exclusively in the soft near ultraviolet range, and emits very little visible light. The black light was invented by William H. Byler, in 1935.
Fluorescent black lights are typically made in the same fashion as normal fluorescent lights except that only one phosphor is used and the normally clear glass envelope of the bulb may be replaced by a deep-bluish-purple glass called Wood’s glass, a nickel-oxide–doped glass, which blocks almost all visible light above 400 nanometers. In practice, partly due to cost but mainly because Wood’s glass does not make a satisfactory material for lamp manufacture, the lamp will be made from normal glass and a relatively thin coating of a UV filtering material is applied to the exterior. The color of such lamps is often referred to in the trade as “blacklight blue” or “BLB.” This is to distinguish these lamps from “bug zapper” blacklight (“BL”) lamps that don’t have the filter material
Color And Designs
Black light Tattoos are usually colorless when in broad light but can be seen using ultraviolet lights. These are the kinds of tattoo that will just take a few weeks to heal maybe 1 to 1 1/2 weeks maximum. When its completely healed, some black light tattoo leave no trace the tattoo process unless off course you use a black light while some leave some sort of light inked color.
These are tattoos that can be inked in any parts of the body. From you head to your fingers in your feet. There a photo above that show a black light tattoo inked in a mans fingers or knuckles.
