Flashlight Blacklight is good for people. A blacklight, also refered to as a UV-A light, Wood's lamp, or simply untraviolet light, is a lamp which emits long wave (UV-A) ultraviolet light and not much visible light.

There are many kind of blacklights such as Fluorescent,"Bug zapper" tubes, Incandescent, Mercury vapor. The Ultraviolet radiation is invisible to the human eye, but illuminating certain materials with UV radiation causes the emission of visible light, causing these substances to glow with various colors. This is called fluorescence, and has many practical uses. Black lights are required to observe fluorescence, since other types of ultraviolet lamps emit visible light which drowns out the dim fluorescent glow. One of the innovations for night and all-weather flying used by the US, UK, Japan and Germany during World War II was the use of UV interior lighting to illuminate the instrument panel, giving a safer alternative to the radium-painted instrument faces and pointers, and an intensity that could be varied easily and without visible illumination that would give away an aircraft's position. This went so far as to include the printing of charts that were marked in UV-fluorescent inks, and the provision of UV-visible pencils and slide rules such as the E6B.
