Blacklight fluorescent tubes. The violet glow of a blacklight is not the UV light itself, but visible light that escapes being filtered out by the filter material in the glass envelope. A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ultraviolet light and very little visible light.
Black light paint or black light fluorescent paint is luminous paint that glows under a black light. It is based on pigments that respond to light in the ultraviolet segment of the electromagnetic spectrum. The paint may or may not be colorful under ordinary light. Black light paint should not be confused with phosphorescent (glow-in-the-dark ...
The lamps used have very narrow bandwidth, compared to regular fluorescent black lights. Therefore, UV LEDs are claimed to be completely safe, causing no damage to eyes nor risks of skin cancer. When the black light falls upon UV-visible ink, it makes the ink fluoresce so that it emits visible light, making the message readable by human eyes. [4]
Two black light fluorescent tubes, showing use. The longer tube is a F15T8/BLB 18 inch, 15 watt tube, shown in the bottom image in a standard plug-in fluorescent fixture. The shorter is an F8T5/BLB 12 inch, 8 watt tube, used in a portable battery-powered black light sold as a pet urine detector.
Fluorescent body paint under a black light. Fluorescent paints 'glow' when exposed to short-wave ultraviolet (UV) radiation. These UV wavelengths are found in sunlight and many artificial lights, but the paint requires a special black light to view so these glowing-paint applications are called 'black-light effects'.
Black-Light Blue lamps: These lamps are similar to the regular black light lamps, except they use wood's glass as a filter to reduce the amount of visible light emitted. These lamps are used for fluorescence effects where less visible light is ideal. 09 N/A Sun-tanning lamps: These lamps produce wide or narrow band UV-B radiation 10 BL Black ...

This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
