With the compact Brandson LED UV flashlight, you have an effective ultraviolet detector at hand in any situation. It helps you detect invisible contaminants and clean affected areas from liquids, dirt, and stains. This is especially helpful for incontinent pets. The affected areas glow brightly under the beam of light. The black light lamp is most effective in the dark. Measuring only 10 cm in length, the UV flashlight is ideal for on-the-go use. In unfamiliar surroundings, such as hotels, you can uncover hygiene deficiencies and protect yourself from germs. It is also perfect for currency identification and verifying the authenticity of driver's licenses, ID cards, and passports. Collectors can use the UV lamp to spot differently glowing minerals (e.g., amber). The application possibilities are almost limitless. Batteries are not included.
