A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ( UV-A) ultraviolet light and very little visible light.
Learn how black lights produce ultraviolet light that makes some objects glow in the dark. Find out how phosphors, fluorescent materials and black light applications work.
- Limited exposure shouldn’t cause any issues, but prolonged eye contact without eye protection can cause retina damage.

Jun 4, 2020 · Black light is ultraviolet light that is invisible or “black” to the human eye. Learn about the different types of black lights, how they work, and what they are used for in science, art, medicine, and more.
- Which Ultraviolet Blacklight Lighting Technology is Best? For most applications and installations, UV blacklights are available either as a fluorescent lamp or an LED light.
- How Much UV Do I Need? UV blacklight "brightness" is a difficult metric to describe, because UV light energy is not directly visible. Although lumensis typically the metric used to measure the amount of visible light, because ultraviolet light is invisible, this metric is essentially useless.
- Which Wavelengths of UV Do I Need? Ultraviolet light encompasses a wide range of wavelengths, but most blacklight applications utilize a narrow range of ultraviolet radiation (UV-A) to produce fluorescence effects - specifically between 350 and 400 nm (nanometers).
- What Type of UV Light Fixtures Should I Use? Finally, when choosing a UV light fixture, you should know that they can come in a variety of shapes and forms.
May 1, 2024 · Learn about the science of fluorescence and the everyday items that glow under a black light. See examples of fluorescent substances, such as tonic water, vitamins, chlorophyll, scorpions, and more.
Are black lights magic? Nope! They're simple tools that take advantage of science. Let's take a closer look at black lights and why they make things glow. Black lights are made in much the same way that regular incandescent or fluorescent lights are made. The primary difference is in the glass, coatings, or filters that are used in black lights.
