Wurkkos TS10 vs. Sofirn SC31 Pro: Anduril 2, Two Sizes
Both lights run the same enthusiast firmware, but they are different tools. The TS10 is a 14500 pocket rocket the size of your thumb; the SC31 Pro is an 18650 workhorse with triple the staying power. Same family of firmware, opposite answers to "what kind of carrier are you."
The short version: Buy the SC31 Pro if this is your first and only enthusiast light — it's the same Anduril 2 firmware with a bigger battery, better sustained output, and USB-C charging. Buy the TS10 if you want a tiny, high-CRI carry light that disappears in a watch pocket and you don't need to run it beyond short bursts.

The differences at a glance
| Feature | Wurkkos TS10 | Sofirn SC31 Pro |
|---|---|---|
| Maximum output | 1,400 lumens (rated burst) | 2,000 lumens (rated) |
| Emitter | Triple LED, high-CRI options | Luminus SST40, high-CRI variants |
| Battery | 1× 14500 (runs on AA reduced) | 1× 18650, replaceable |
| Charging | USB-C, in-light | USB-C, in-light |
| Firmware | Anduril 2 | Anduril 2 |
| Aux LEDs | Yes — findable in the dark | No |
| Beam profile | Wide flood, minimal hotspot | Flood with usable hotspot |
| Size | Watch-pocket sized | Marker-pen sized |
| Sustained output | Steps down hard, little thermal mass | Holds a higher plateau longer |
Output figures are manufacturer-rated. The TS10's 1,400 lumens is a short burst from a body with almost no thermal mass; judge it on sustained output. The SC31 Pro's 18650 body sustains output better, which is the practical benefit of its extra bulk.
Sofirn SC31 Pro: the Anduril gateway drug
If you've just discovered Anduril and want to learn it properly, this is the better classroom. The SC31 Pro is the standard bearer for enthusiast value: 2,000 rated lumens, a 226 m beam, a replaceable 18650, USB-C charging, and the full firmware — for around thirty dollars.
Two things make it the better first purchase. First, the battery: a standard 18650 you can swap in seconds and replace anywhere, which makes it genuinely useful in an emergency rather than just interesting. Second, sustained output: the larger body handles heat far better, so the light stays usable on its mid-to-high levels instead of collapsing after a minute of turbo.
Pros
- Triple the battery capacity of a 14500
- Sustains output much better
- 226 m reach — usable hotspot and spill
- Replaceable 18650, USB-C charging
- Cheap enough to experiment with Anduril
Cons
- Too big for slim jeans pockets
- Standard SST40 tint is cool, slightly green
- Functional rather than premium finish
- You're carrying an 18650 tube for a pocket light
Buy the SC31 Pro if: this is your first enthusiast light, you need it to run for real work sessions, or you want the flexibility of a standard battery. Check it on Amazon, and grab two spare cells and a real charger.
Wurkkos TS10: the pocket-sized enthusiast toy
The TS10 is the most fun you can have for about twenty-five dollars — but it's a different job. It lives in a watch pocket and disappears, which makes it far more likely to be on you every single day. If the SC31 Pro is a workbench tool, the TS10 is the one that's always in reach.
Its signature is the beam. Three LEDs behind a triple optic produce a wide, even flood with very little hotspot — ideal for a toolbox, an engine bay, a dark stairwell, and all wrong for spotting something across a field. The high-CRI options are the reason to buy it: at 90-plus CRI, colors look real instead of clinical, which matters for inspection-type tasks.
There is serious fine print. The 1,400-lumen figure is a short burst — the head gets uncomfortably warm in under a minute and Anduril pulls it back hard. Battery capacity is 600 mAh-ish (a single 14500), so real runtime is short. And Anduril on a light this tiny is a lot of interface for people who don't want a hobby. Hand it to a family member during a power cut and you'll get it back strobing.
Pros
- Watch-pocket sized — always on you
- High-CRI emitter options are genuinely good
- Aux LEDs make it findable in the dark
- USB-C charging; runs on AA in a pinch
- Absurd output-to-size-to-price ratio
Cons
- Steps down hard on turbo; little sustained output
- Pure flood — no usable throw
- Small 14500 cell limits runtime
- Anduril is confusing for newcomers
- QC varies more than premium brands
Buy the TS10 if: you want a tiny high-CRI carry light, you already own a solid main light, and you're comfortable with Anduril. Check the TS10 on Amazon. It goes out of stock regularly, so the search link surfaces current listings.
The winner
The Sofirn SC31 Pro wins as a first purchase. Same firmware, better sustained output, a replaceable 18650, and USB-C — the better classroom for Anduril and the more useful light in an emergency. Its only real weakness is pocket size.
The Wurkkos TS10 wins as a second light. If you already carry something bigger and want a watch-pocket high-CRI light that lives on you, the TS10 is the more fun and more likely to actually be carried. Pure flood and short bursts are fine when it's not your main tool.
Neither is for someone who just wants a flashlight. For that, see our top picks or the Baton 4 — and read our lumens vs. throw explainer if the flood-versus-throw trade-off here feels new.

Frequently asked questions
Which is brighter, the Wurkkos TS10 or the Sofirn SC31 Pro?
On paper the SC31 Pro: 2,000 rated lumens versus 1,400 for the TS10, and the SC31 hits a bigger battery and a longer-reaching beam. But the gap that matters is sustained output — the 18650 SC31 Pro holds its output far better than the tiny TS10, which steps down hard within a minute.
Do the TS10 and SC31 Pro use the same firmware?
Yes — both run Anduril 2, the widely loved open-source flashlight firmware. Everything you learn configuring one carries over to the other, which is part of why they partner well as a first pick and a pocket second.
Can the TS10 use a regular AA battery?
It will run on a standard AA alkaline or NiMH cell at dramatically reduced output, which is a useful emergency fallback. For the real 1,400-lumen experience you need a 14500 lithium-ion cell, charged in-light over USB-C.
Is the TS10's high-CRI version worth it?
Yes, if you use a light to inspect anything — wiring, paint, skin, food — where color matters. High-CRI trades roughly 20 percent of the lumens for colors that look real instead of grey and muddy. Almost nobody who tries it goes back.
