Olight Arkfeld UV Review: A Flat EDC Flashlight with an Ultraviolet Trick Up Its Sleeve

Introduction

Olight’s Arkfeld line has built a strong following among everyday-carry fans thanks to its flat, pocket-friendly shape and a unique dual-sided design: white light on one end, and a switchable tool on the other. The Arkfeld UV takes that formula and replaces the green laser found on the standard model with an ultraviolet emitter, opening up a very different set of uses.

At an MSRP of $79.99, and frequently discounted (it was offered at $59.98 during a recent sale), the Arkfeld UV sits in a surprisingly reachable price range for a specialty light. But is a UV version of an already popular EDC flashlight worth it? Here is how it breaks down.

Who the Arkfeld UV Is For

The core Arkfeld platform is, frankly, one of the best flat EDC flashlights around. The standard version puts out 1,000 lumens on turbo, which is genuinely bright for its size, and the slim rectangular body disappears into a pocket. The UV model keeps all of that: the same five lighting modes, the same 1,000-lumen output, and the same flat form factor that has made the line a favorite.

The difference is what happens when you flip the light over. Instead of a green laser, you get an ultraviolet emitter. That single change moves this light into a more niche role, and whether it suits you depends entirely on whether you will actually use UV output.

Main Strengths

The headline feature is the ultraviolet emitter, and it is a strong one. In a darkened room it produces a clearly visible UV beam with no brightness levels or mode cycling: it is simply on or off, which keeps operation simple. Switching between white light and UV is done by flipping the light over, just like the laser-equipped model.

The most obvious real-world use is travel. If you spend a lot of nights in hotels, a UV light is a quick way to check how clean the bedding and surfaces really are. For frequent travelers who care about that sort of thing, this could easily become the default travel flashlight. If you would rather not know how clean that hotel bed is, that is a fair reason to skip the UV version entirely.

Beyond the UV emitter, Olight made several meaningful refinements to this model:

• Anti-slip grips: New grip grooves on both sides of the body. Three fingers naturally land on them during a normal grip, which noticeably improves purchase compared with the smooth-sided standard model.
• Slimmer tail: Three millimetres have been trimmed from the bottom (a 19mm tail is now 16mm), so the light sits slimmer in pockets. The magnetic charging port was reshaped to fit, but charging works as normal, and the light still tail-stands, just with slightly less surface area.
• Two-way pocket clip: The standard Arkfeld uses a one-way clip; this model gets a two-way clip, so you can mount it on the brim of a hat and still use the UV function hands-free.
• Lanyard hole: A small lanyard hole at the top of the pocket clip, something the standard model lacks.

Under the hood, the battery appears unchanged: a built-in 1,050mAh 3.7V lithium polymer cell.

Things to Consider Before Buying

The biggest caveat is the same one that applies across the Arkfeld line: the battery is built in and not removable. For many buyers this is the single largest downside, and it is worth thinking about before committing, since a sealed cell is a long-term ownership consideration.

The second consideration is more fundamental. The UV emitter makes this a specialty light. If you have no practical use for ultraviolet output, there is little reason to choose this version over the standard Arkfeld with the green laser, which offers more everyday utility for most people. The UV model earns its place only if checking hotel rooms, inspecting surfaces, or other UV tasks genuinely fit your routine.

Buying Advice

If you already love the Arkfeld form factor and have a real use for UV, this is an easy recommendation. The refinements Olight made here, including the anti-slip grips, slimmer tail, two-way clip, and lanyard hole, are exactly the kind of updates worth hoping for on future Arkfeld releases.

At its sale price of $59.98 (down from the $79.99 MSRP), the value proposition improves considerably. Timing matters: Olight runs limited-time promotional windows, so waiting for a sale event can shave a meaningful amount off the sticker price.

Conclusion

The Olight Arkfeld UV is a well-executed twist on an already excellent EDC platform. The white light performance is unchanged and strong at 1,000 lumens, the UV emitter is genuinely useful for travelers and cleanliness-focused users, and the hardware refinements make the light easier to grip, slimmer in the pocket, and more versatile to carry. The built-in battery remains the main compromise, and the UV function is only worth it if you will actually use it. For the right buyer, though, this is a thoughtfully updated specialty light at a fair price.
