Blacklight lamps are special types of ultraviolet (UV) lights that emit very little visible light. They produce UV radiation, which can make certain materials, like fluorescent dyes and minerals, glow in the dark. These lamps are commonly used in various applications, including artistic displays, security features, and forensic investigations. The most common type of blacklight lamp is the fluorescent blacklight, which uses a phosphor coating to convert UV light into visible light. Blacklight lamps are often found in nightclubs, theater productions, and science experiments, where their unique ability to highlight specific colors and patterns is utilized.
