![]() ![]() Despite the small size, it touts an impressive 51 LED bulbs, each of which can shine for over 100,000 hours. The tool itself is easy to operate, with a single-button control located at the back of the device. It twists off and opens up to the battery housing which accepts three double-A batteries. This makes it easy to place and remove the power source. Once closed, it seals well, ensuring an entirely waterproof design. Coupled with the slip-resistant handle, this UV flashlight is both user-friendly and highly durable.

My main focus is on tactical supplies, outdoors gear, and survival products. You can find my recent work on Narcity Media, Car Bibles, and The Drive. I use my sciences education and personal experience to provide Task and Purpose readers with objective assessments on things like tactical gloves, hydration packs, bug-out backpacks. To pin down the best UV flashlights available, we started with the history of the tech - back to when UV radiation was discovered in 1801. Fast-forwarding to the 21st century, we looked into the uses of UV rays in forensics, security, and biology. We then tracked down products with all the features necessary to function in any of these roles. Considering the lighting technology, power source, and structure, we whittled down the results even further. ![]() We chose the products on this list due to their balance of budget and function, in addition to their overall versatility. While all UV flashlights have a lot in common, there are a few different types from which to choose. It all comes down to how you plan to use the light. Professional applications rely on an intense beam that is powerful and reliable. Typically, preferred models for work have a large metal structure with a prominent handle. Generally, these will have closer to 100 individual LED bulbs. Conversely, UV flashlights for personal use tend to be more compact, often coming in a pocket-sized design. Bulbs: Modern UV flashlights rely mainly on LED technology.While both types rely on beams of the same wavelengths, those used personally tend to have far fewer individual LED bulbs. ![]() These powerful bulbs, when used for blacklight applications, emit a wavelength of approximately 395 nanometers. Batteries: Because of the portable nature of the devices, UV flashlights are battery-operated.This causes the searched-for fluids to fluoresce, making them visible to the naked eye. ![]() In most cases, the lights require replaceable batteries which are usually double-A. Generally, the batteries are located in the handle. Sturdiness: Another important feature of a UV flashlight is the strength of the design.With a twist-off design, the power supply is easy to access, making it easy to change the batteries. ![]()
