A black light, also referred to as a UV-A light, Woods light, or simply ultraviolet light, is a lamp that emits long wave (UV-A) ultraviolet light and not much visible light.[1][2][3][4] The lamp has a violet filter material, either on the bulb or in a separate glass filter in the lamp housing, which blocks most visible light and allows through UV,[3] so the lamp has a dim violet glow when operating.[5][6] Black light bulbs which have this filter have a lighting industry designation that includes the letters BLB.[3][5]\r
\r
A second type of bulb, which is also called a black light, produces ultraviolet but does not have the filter material, so it produces more visible light and has a blue color when operating.[3][4][5] These are made for use in bug zapper insect traps and are identified by the industry designation BL.[5][6]\r
\r
Black light sources may be specially designed fluorescent lamps, mercury vapor lamps, light-emitting diodes, lasers, or incandescent lamps.[5][6] In medicine, forensics, and some other scientific fields, such a light source is referred to as a Woods lamp (named after Robert Williams Wood).\r
\r
Although many other types of lamp emit ultraviolet light with visible light, black lights are essential when UV-A light without visible light is needed, particularly in observing fluorescence,[4][5] the colored glow that many substances emit when exposed to UV. Black lights are employed for decorative and artistic lighting effects, diagnostic and therapeutic uses in medicine,[3] the detection of substances tagged with fluorescent dyes, rock-hunting, the detection of counterfeit money, the curing of plastic resins, and attring insects.[4] Strong sources of long-wave ultraviolet light are used in tanning beds.[4] Although the low power UV-A emitted by black lights is not a hazard to skin or eyes and can be viewed without protection, powerful ultraviolet sources present dangers and require personal protective equipment such as goggles and gloves. \r
