The black inspection tube is constructed from blue-black glass, and the inner tube wall is coated with phosphor. This type of light emits only ultraviolet wavelengths in the range of 300-400 nm, with a central value of 365 nm. It can render ultraviolet light invisible while converting it into visible light, a phenomenon known as fluorescence. This makes it suitable for a wide range of applications involving fluorescence analysis.

Applications:
Appraisers use these lights to detect the authenticity of antiques. Many modern pigments contain phosphorus, which fluoresces under black light, while most ancient pigments do not.
Maintenance personnel employ them to locate invisible cracks in machinery. They inject a small amount of fluorescent dye into the fuel supply and illuminate it with black light.
Law enforcement officials use them to verify the authenticity of currency. Many countries, including the United States, incorporate an invisible fluorescent strip on their larger denominations, visible only under black light.
Forensic scientists use them to analyze crime scenes. For capturing fingerprints, for example, a fluorescent dye is often sprinkled under black light.
Insect capture: Insects are particularly drawn to this type of light, making it useful for insect capture purposes.
