10 Best Uv Flashlights 2025 in the United States

The OLIGHT Arkfeld Pro is a versatile flashlight that shines in the UV flashlight category with its three-in-one functionality combining white light, UV, and green beam. With a maximum brightness of 1300 lumens and a high UV intensity output of 900mW at a 365nm wavelength, it stands out as a reliable tool for both outdoor emergencies and everyday tasks. The robust aluminum build adds to its durability while keeping it lightweight at just 6.4 ounces, making it easy to carry in your pocket.

One of its strengths is the intuitive circular selector that allows seamless switching between lighting modes, catering to different needs effortlessly. The inclusion of a five-level battery indicator is a thoughtful feature, ensuring users are always aware of their power level, which enhances usability during critical situations.

However, while the flashlight showcases excellent performance, the relatively compact size may limit the brightness range compared to larger models. Additionally, the reliance on a lithium polymer battery means that users will need to be mindful of recharging it regularly to avoid running out of power unexpectedly. The product is also waterproof, which is a definite plus for outdoor use, but it’s important to handle it with care to maintain its longevity.

The OLIGHT Arkfeld Pro is a solid choice for anyone in need of a reliable multi-functional flashlight, especially for those who require UV capabilities. It suits outdoor enthusiasts, emergency responders, or anyone who values versatility in a portable light source. Though it has a few minor drawbacks, its strengths make it a compelling option in the UV flashlight market.

The Streamlight 66149 Stylus Pro USB is a compact and durable UV flashlight designed for a variety of uses, including professional and amateur applications both indoors and outdoors. One of the standout features is its 400nm ultraviolet LED, which provides a strong light intensity at 325 mW. This makes it suitable for tasks like detecting counterfeit currency, checking for pet stains, or even inspecting certain materials.

The flashlight is rechargeable via USB, allowing for convenient use without the need for disposable batteries, and the lithium-ion battery fully recharges in just 2.5 hours, providing a runtime of 2.5 hours on a single charge. The inclusion of a nylon holster makes it easy to carry and store. Additionally, it boasts a water-resistant design, which adds to its durability and makes it suitable for various environments.

Potential drawbacks to consider include the absence of standalone lithium batteries, meaning you'll need to rely on the built-in rechargeable battery. While the metal sleeve offers protection for the USB port, the flashlight may be slightly bulkier compared to non-rechargeable penlights. For those seeking a reliable, portable UV flashlight with solid performance, the Streamlight Stylus Pro is a strong contender, but it might not be the best fit for users preferring a lighter or simpler device.

The GearLight UV Black Light Flashlight S100 is a compact and portable UV flashlight ideal for tasks like leak and hotel inspections, detecting pet urine, bed bugs, scorpions, stains, and dye detection. It emits a bright ultraviolet light which can highlight areas not visible to the naked eye, making it a useful tool for both home and professional use. The flashlight is powered by two AAA batteries (not included), which means it is easy to find replacements but could also mean frequent battery changes depending on usage.

The build quality is notable, as it is made from military-grade aluminum, ensuring durability and the ability to withstand rough handling and brief water exposure. Its small size (5.25 x 0.5 x 0.5 inches) and lightweight (1 ounce) make it highly portable and easy to carry around with the included pocket clip.

However, being powered by AAA batteries might limit its light intensity compared to larger, more robust models. Additionally, it may not be the best choice for extensive use due to the potential for frequent battery replacements. The flashlight is versatile, capable of authenticating documents, inspecting currency, and curing resin, but it may lack the power of larger UV flashlights. This UV flashlight is well-suited for those needing a portable and durable option for occasional use.
