Olight Arkfeld Pro: The Flat EDC Flashlight That Does Green Laser and UV Too

Introduction

Flat flashlights have quietly become one of the most practical everyday-carry upgrades of the last few years, and the Olight Arkfeld Pro sits right at the front of that pack. This latest version arrives in a new red-and-gold color scheme that feels like a deliberate nod to 1970s styling, with gold highlights and a chromed charging port area. It is a retro look with very modern internals, and it is a strong option if you are considering your first flat carry light.

What Makes the Arkfeld Pro Different

The headline number is output: the Arkfeld Pro can kick out up to 1,300 lumens, though not for long, before it throttles down and settles at about 420 lumens, which is also its sustained high setting. That is a lot of light for a small, flat, deep-pocket-friendly flashlight.

Below high, the scale steps down through a 100-lumen medium, a 15-lumen low, and then a moonlight mode that is genuinely useful. Moonlight lets you turn the light on in very dark spaces without blowing out your night vision, and on that setting the light can run for up to 11 days. Low gives you roughly 55 hours of runtime.

That combination of form factor and output range is what makes flat lights so appealing, and the Arkfeld Pro is a standout example of the category.

The Green Laser: The Real Party Trick

Built into the side switch is a very strong green laser with a beautifully tight beam. The beam does not spread much and stays very round, which is not something you see on cheaper inexpensive lasers, where the beam tends to fracture. That clean dot says a lot about the quality of the lens inside.

If you have not used a green laser before, they are genuinely fun to carry. Green beams interact with water vapor and water molecules in the air, so on humid evenings they can look like lightsabers shooting across the sky.

UV and Switchable Light Modes

The third output is UV, running at a 365 nanometer wavelength, which is a question that comes up often for buyers. It throttles just like the visible light does, starting near 900 milliwatts and dropping to about 560 milliwatts, with roughly five hours of runtime available on UV.

The clever part is the switching. Once the light is on, you can flick back and forth between UV and visible light without cycling modes. If you spot something under UV but cannot quite tell what it is, you can flick over to visible light to inspect it, then flick straight back. That makes quick inspections far less fiddly.

Strobe and a few other modes round out the feature set, all controlled from the same switch.

Battery Life and Everyday Use

Inside is a 1,500 milliamp 3.7 volt battery, and it is not user serviceable. That is the most common complaint about this type of light. In practice, though, these flashlights are usually lost, worn out, or obsolete long before battery degradation becomes a real problem, so it is worth weighing against everything else the light offers.

For daily carry, the moonlight runtime is the quiet hero here. Eleven days on moonlight means you can leave it ready on a nightstand and never worry about charging it before an outage or a late-night trip.

Buying Advice

The Arkfeld Pro earns its place if any of these describe you:

• You want one slim pocket light that covers visible light, laser, and UV inspection in a single body.
• You care about a clean, focused laser beam rather than a cheap, fractured one.
• You need very long moonlight runtime for dark rooms and emergencies.

If you expect to replace the battery yourself someday, this is not the light for you. Everyone else will find very little to complain about.

Conclusion

Olight keeps refining the flat flashlight formula, and the Arkfeld Pro is one of its strongest expressions yet: serious output, a superb green laser, useful 365nm UV, and exceptional low-mode runtime, all wrapped in a pocket-friendly flat body. The non-serviceable battery is the trade-off, but for most people this is one of the best flat carry lights you can buy today.
