10 Best Black Light Flashlights 2026 in the United States

The OLIGHT ArkPro Ultra is a versatile and durable flashlight that stands out with its combination of four light modes: a bright 1700-lumen white floodlight, an 800-lumen spotlight, a 365nm UV light, and a green beam. This variety makes it well-suited for different situations like camping, emergency use, and everyday carry. The UV light is especially useful for detecting stains and leaks, while the green beam can be combined with the other lights for various lighting effects.

It has strong battery life, lasting up to 14 days on the lowest setting, and recharges easily via magnetic USB or USB-C cables. Built from Olight’s proprietary aluminum alloy, it’s tougher than typical flashlights, resistant to scratches and dents, which is great if you plan to use it outdoors or in demanding conditions. The rectangular design fits comfortably in the hand and its clip and magnetic base add to its convenience for hands-free use.

Its rectangular shape might feel unusual compared to standard round flashlights, and while it is portable, it’s slightly larger than compact single-purpose UV lights. Also, the green beam’s power is limited to 5mW, which is adequate but not very strong for specialized tasks. For those needing a multi-function flashlight that combines strong white light with UV and green beams, and value durability and battery life, the ArkPro Ultra is a solid choice. For a simple, very compact UV-only flashlight, something smaller might be preferable.

The OLIGHT ArkPro is a versatile black-light flashlight that also offers bright white and green beams, making it a handy all-in-one tool for outdoor activities, emergencies, and work tasks. It features four light sources including a UV light and a green beam, with independent control allowing you to mix these lights as needed. The white LED can reach up to 1500 lumens, providing strong floodlight and spotlight options that can shine up to 205 meters, which is excellent for both wide-area illumination and focused distance lighting. The green beam is limited to safe output levels (≤5mW), suitable for specialized uses like hunting or navigation.

Its rechargeable lithium polymer battery offers up to 72 hours of runtime, and charging is convenient via USB-C or a magnetic dock. The flashlight is compact and flat, designed for comfortable pocket carry and easy handling, while its 6061 aluminum alloy body ensures good durability and water resistance with an IPX7 rating, meaning it can survive short water exposure. Additional practical features include ergonomic buttons, a dual-direction clip for hands-free use, and clear status indicators for battery and brightness levels.

The flat rectangular shape might not feel as traditional as cylindrical flashlights to some users. Also, while it includes multiple beams, the UV and green lights are less bright, which is typical but worth noting if those are your main interest. This flashlight serves as an excellent choice for those seeking a reliable, multi-functional lighting tool that fits easily in a pocket and can handle outdoor conditions, especially if the combination of white, UV, and green lights in one compact device is important.

The OLIGHT Arkfeld Pro is a versatile and compact flashlight that combines a bright white LED with a strong UV light, making it suitable for everyday carry and various uses like outdoor activities, cleanliness checks, or even pet interaction. It delivers a powerful 1300 lumens of white light, which is bright enough for most tasks, while its UV light operates at a professional-grade 365nm wavelength with an output of up to 900mW, providing a purer and more effective black light compared to many competitors that commonly use 395nm. This makes it particularly useful if you need reliable UV detection or inspection.

Powered by a rechargeable lithium polymer battery, the flashlight can run up to 55 hours on lower settings, and it features a handy five-level battery indicator so you always know when to recharge. Its IPX7 waterproof rating and sturdy aluminum build mean it can handle everyday bumps and wet conditions, adding to its durability. The flat, rectangular design fits comfortably in a pocket, making it very portable and easy to carry daily.

Some users might prefer a more traditional cylindrical shape for grip comfort during prolonged use despite the flat design being great for portability. Although the maximum 1300 lumens is bright, it is not the highest available on the market if extreme brightness is needed. Additionally, running the UV or white LEDs at full power will noticeably reduce the runtime compared to lower modes. The OLIGHT Arkfeld Pro is a well-built, easy-to-use flashlight that excels in providing both quality white light and a powerful, professional-level UV light in a compact, everyday carry form, making it an excellent choice for those who value portability, durability, and versatile lighting options.
