What are the two beam angles on the Sofirn SK31?

The SK31 has a 66-degree spill beam for wide area coverage and a focused 9-degree hotspot for long-distance reach. Both operate at the same time.

How does the Command Ring work?

Twisting the Command Ring switches between two interfaces. One jumps straight to full output, and the other cycles through six brightness levels from Turbo down to Moonlight, with mode memory that returns the light to your last-used setting.

Does the SK31 have a way to prevent the battery from draining in storage?

Yes. It has a mechanical lockout that physically cuts the circuit, so the light cannot accidentally activate or drain while stored in a bag or pack.

What kind of charging port does the SK31 use?

It uses a built-in USB-C port sealed directly into the head of the light, with no separate rubber cap that could be lost.

Sofirn SK31 - 6800 Lumen Tactical Flashlight REVIEWED

The Sofirn SK31 is a high-output tactical flashlight rated at 6800 lumens and 1295 feet of throw, and CommQuest’s review finds it earns that spec in practical use, with a dual-beam design and a dual-interface system that make it genuinely versatile rather than just a big number on a box.

What You’re Actually Getting

The SK31 is built around a combination of reach and coverage that most flashlights sacrifice one for the other to achieve. A 66-degree spill beam handles the area right around you, while a tight 9-degree hotspot pushes light deep down a fence line or across open ground. You get both at the same time, which is the detail that makes this light useful in practice rather than just impressive in a spec sheet.

The body is sized and weighted for real carry. The tail switch is a forward-clicky design, so you can activate it with one hand, no looking down required. Gloves on or off, that works the same either way.

Two Interfaces, One Twist

The Command Ring is a physical selector that sits on the light itself. Twist it one way and the SK31 jumps straight to full output the moment you hit the switch. Twist it the other way and you get six brightness levels, running from Turbo all the way down to Moonlight. Mode memory means the light comes back on at whatever level you left it, so if you were running it dim to read a map, it stays dim until you tell it otherwise.

That kind of flexibility covers a wide range of tasks without requiring you to cycle through unwanted modes in the dark, which is a real frustration with cheaper lights.

Charging and Battery Life

Charging runs through a USB-C port built directly into the head, sealed in place with no rubber cap to misplace. The internal cell is a 5000mAh unit. A four-level battery indicator shows you where you stand before you head out, which matters more than most people realize until they’re standing somewhere dark wondering if the light will last. A mechanical lockout physically cuts the circuit so the light can’t drain on its own while it sits in a bag or a vehicle.

Who This Light Is For

The SK31 suits anyone who regularly works in low-light conditions and needs a light they can depend on without fumbling. Security work, trail use, property checks, emergency preparedness. The forward-clicky switch and one-hand activation are small things that add up fast when conditions are genuinely rough. The dual interface means the same light handles close-up tasks and long-distance tasks without a compromise.

Honest Take

The 6800-lumen figure and 1295-foot throw are the headline numbers, but the more interesting parts are the practical ones. The sealed USB-C port, the mechanical lockout, the dual-beam coverage, the mode memory. Those are the features that tell you the designers thought about how people actually use a light, not just how it looks in a product listing. CommQuest’s assessment is that the SK31 earns its place as a serious piece of carry gear.
