Why choose this flashlight?
Ultraviolet is a type of electromagnetic radiation with a wavelength from 10-400 nm, shorter than visible light but longer than X-rays. UV makes certain substances “fluoresce” because they absorb the UV and re-radiate the energy at a longer wavelength. It is what makes black-light posters glow and skin tan.
