Sofirn SC21 vs Sofirn SP10 Pro
Quick take: The Sofirn SC21 is brighter (1,000 vs 900 lm); the Sofirn SC21 throws farther (143m vs 119m).
Which one to buy
Twenty dollars each, the same Samsung LH351D at 5000K and CRI 90, IP68 on both, and only one is still made. The Sofirn SC21 is discontinued, so the Sofirn SP10 Pro is the one you can count on finding.
The SC21 was the more complete package. Owners describe a magnetic tail, a deep-carry clip, onboard USB-C and a cell in the box, with a floody beam and defined hotspot rated at 1,000 lumens. Their reservations: low-voltage protection only engages on turbo, so lower modes can over-discharge the cell; one reviewer's first sample had a mushy switch; runtime is short; and the USB port placement draws complaints. Owners also warn that the later SC21 Pro is a different light, so check listings.
The SP10 Pro is the cheapest way into Anduril 2 on AA format, and it runs a 14500 or any button-top AA, so a gas-station battery keeps it going. Owners praise a moonlight one reviewer called the lowest they'd used on any light. The complaints are a green tint, output that isn't perfectly regulated on 14500, weak efficiency on high and a clip that needs more ramp. It has no onboard charging or magnet.
If you find a new SC21, it's the handier everyday light with its magnet and USB-C. Otherwise, the SP10 Pro is the buy, especially if AA compatibility or a very low moonlight matters to you.
Sofirn SC21
Only if you find one new: a magnetic, USB-C pocket light with high CRI, provided you recharge before the cell runs flat on low.
Sofirn SP10 Pro
For buyers who want Anduril 2, a very low moonlight and a light that runs on any AA, and don't mind charging cells separately.

What owners report
Sofirn SC21
- ✓High-CRI emitter at a price where colour rendering is usually the first thing cut
- ✓Magnetic tailcap and a genuinely deep-carry pocket clip
- ✓USB-C charging with the 16340 cell included
- ✓Floody beam with a defined hotspot — a sensible general-purpose EDC profile
- ✓16340 size makes it small enough to actually carry every day
- ✓Complete package for around $21
- ✗Low-voltage protection only engages on turbo, so lower modes can over-discharge the cell
- ✗One reviewer's first sample had a mushy switch; a second unit didn't
- ✗Runtime is short, as any 16340 light's is
- ✗USB port placement draws criticism
- ✗Easy to confuse with the newer SC21 Pro, which is a different light
Sofirn SP10 Pro
- ✓Anduril 2 on an AA-format light, and the only one that also takes 14500
- ✓Exceptionally low moonlight mode — among the lowest available anywhere
- ✓High-CRI Samsung emitter at a sunlight-like 5000K
- ✓Takes any button-top AA or 14500, including longer protected cells
- ✓Regular price just over $20
- ✗The emitter tends toward a green tint
- ✗Efficiency is unimpressive on high, though good in the medium modes
- ✗Output isn't perfectly regulated on 14500
- ✗The pocket clip needs more ramp to slide onto a pocket easily
- ✗Anduril on a light this simple is more interface than some owners want
Sofirn SC21 vs Sofirn SP10 Pro: common questions
Does the Sofirn SP10 Pro have a magnet and USB-C like the SC21?▾
No. The SP10 Pro has neither, so you charge 14500s in a separate charger or run AAs. Owners of the SC21 single out its magnetic tail and onboard USB-C charging.
Which has the better tint for the money?▾
Both use an LH351D at 5000K and CRI 90. SP10 Pro owners flag a green tint as their most common complaint, while SC21 owners praise high-CRI output at a price where color rendering is usually cut.
