This is a standard 5mm size LED that emitts UV - ultraviolet light. Great for hobby electronics projects and science fair projects wherever UV light is needed (checking counterfitting features of money or credit cards, lighting up glow-in-the-dark stars, making scorpions glow, etc.). Works on 3.5V so two AA batteries in series will do.
