Incandescent Blacklights There are incandescent bulbs made with deep violet-blue bulbs which largely filter out visible light. Longer UVA wavelengths get through the glass and are not blocked by the dark colored filter dye. Most visible violet and some visible blue, as well as a wide range of infrared and the longest, less visible of visible red wavelengths. Some traces of other visible wavelengths get through. These bulbs are a convenient source of some UV to cause fluorescent paints, dyes, and other substances and objects to glow. These bulbs are quite safe, although it may not be a good idea to stare into one from short distances for long periods of time. They generally have hotter running filaments that last only about 500 hours or so. Other Types of "black lights" Do produce light in the UV range, their spectrum is confined to the longwave UVA region.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 WARNING:INTRO
