Introduction to UV Light: Understanding the Power and Potential

Before you start utilizing the power of a UV flashlight, it’s crucial to understand the unique components and potential of ultraviolet light itself. UV or ultraviolet light is a part of the electromagnetic spectrum that’s invisible to the human eye. UV light sits adjacent to the visible light spectrum, at the end with shorter UV wavelengths and greater energy. UV light is classified into three types: UVA, UVB, and UVC.

UVA, or long-wave UV, constitutes most of the UV light that reaches us from the sun. It’s the type of UV light used in black lights and tanning beds. UVB, or medium-wave UV, is less common but more harmful, causing sunburn and contributing to skin cancer. UVC, or short-wave UV radiation, is the most dangerous. Fortunately, it’s almost entirely absorbed by the earth’s atmosphere.

Available in a wide range of wavelength, now, your UV flashlight works by emitting UVA light, the safest form of UV radiation. This light can reveal things that are invisible under normal light, opening up a treasure trove of uses for you. From hunting scorpions to checking hotel room cleanliness, the world is your oyster.
