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 OLIGHT Arkfeld Ultra flashlight stands out for its versatility, combining white LED, UV light, and a green beam in one compact and portable device. With a UV light intensity of 900 mW, it should be effective for tasks requiring UV light such as checking fluorescent markings or inspecting surfaces. The flashlight also delivers a powerful 1400 lumens of white light, which is beneficial for general use, while the green beam is limited to ≤5mW, suitable for signaling or low-light conditions. This three-in-one functionality makes it a practical choice for diverse applications including EDC (everyday carry), outdoor activities, emergency situations, camping, hiking, and jogging.

Its rechargeable lithium polymer battery promises convenience and environmental friendliness, and the inclusion of the battery is a definite plus. The build quality is exceptional, thanks to the O-aluminum construction which offers durability and resistance to wear, ensuring long-term use. The flashlight also has a sleek, modern design with a matte finish that is both appealing and functional.

Additionally, its compact size (0.63 x 1.06 x 4.72 inches) and lightweight nature (4.16 ounces) make it easy to carry around. On the downside, the specific wavelength of the UV light is not provided, which might be a concern for users needing precise UV specifications. The product being ranked #39 in handheld flashlights indicates it is popular but not the top choice for everyone. Despite these minor drawbacks, the OLIGHT Arkfeld Ultra is a strong contender in the UV flashlight category, offering impressive functionality and durability in a sleek, portable package.

The GearLight Black Light UV Flashlight S50 comes in a convenient 2-pack and is designed for a variety of practical uses such as ID checking, leak detection, and pet urine spotting.

The flashlight's LED light source ensures bright and focused illumination, while the compact size and lightweight (just 1 ounce each) make them easy to carry around.

The aluminum and resin build enhances durability, and the non-slip grip is a thoughtful feature for comfortable handling. However, it’s worth noting that the package does not include batteries, so you’ll need to purchase those separately. The battery life and intensity might also vary depending on the quality of batteries used. These flashlights are powered by alkaline batteries, which are commonly available.

Given their water resistance level, they're suitable for various environments but may not withstand full submersion. This product is well-suited for those needing a portable, reliable UV flashlight for home improvement tasks, pet owners, or professionals in need of a compact detection tool.
