395nm UV Flashlight - 21 LED Ultraviolet Blacklight Torch

The 395nm UV light is a handheld ultraviolet flashlight built around 21 UV LEDs that emit light at a 395-nanometer wavelength, making invisible security features and fluorescent materials visible to the naked eye. This UV blacklight torch is most commonly used to verify banknote security threads and ultraviolet markings, helping distinguish genuine currency from counterfeits, and to inspect identity documents and official papers for authenticity. The 395nm wavelength falls within the UVA range, which is effective for exciting fluorescent dyes without the higher energy and safety concerns of shorter-wave UV sources. Powered by three AA batteries and rated at 21 lumens, the flashlight is designed for portable, on-the-go use, and the included wrist strap reduces the risk of drops during field work. Its 21-LED array provides broad, even illumination across the target surface, which is useful when scanning a document or banknote for hidden patterns. Beyond security and verification tasks, this ultraviolet flashlight is also used outdoors to locate scorpions, which fluoresce yellow-green under UV light, and for general fluorescent inspection around the home or workshop.
