A blacklight is a type of lamp that primarily emits long-wave ultraviolet light. Fluorescence must be observed because visible light from other kinds of ultraviolet lamps obscures its faint glow. Black light is frequently used to spot fraud, artifact forgeries, and fake money. Other implementations for it include criminology, glow paint effects, disco lighting, mold inspection, and even scorpion detection. Numerous species glow in the UV light!
With just one touch of your screen, this application shines 120 individual LED bulbs, simulating a blacklight accurately.
