Blacklight tube lights are surprisingly versatile. They're designed to filter out visible light and observe fluorescence, making them a great choice for many different occupations and activities. Blacklights are commonly used for authenticating antiques and bank notes, attracting insects, detecting blood or other body fluids from animals for cleaning purposes, identifying evidence in crime scene investigations, mood lighting in bars or restaurants and lighting laboratory equipment to aid in diagnostics. Blacklights can also be used at home for a fun party vibe and are especially great at bringing out colors in neon paints and wall posters.
