What owners report
Sofirn SP35
- ✓Build quality reviewers rate as good even ignoring the price
- ✓USB-C charging at around 2A — genuinely quick for a single 21700
- ✓Smooth reflector gives a well-defined hotspot and useful throw for the size
- ✓Around 2,000 lumens and 330 m of reach from a common, cheap cell
- ✓Simple to live with — no firmware to learn
- ✗Cool, low-CRI SST-40; colours look washed out next to a high-CRI light
- ✗Sofirn's thermal sensor calibration can trigger early step-down on this generation
- ✗No magnetic tailcap
- ✗Beam is unremarkable — competent rather than clean
- ✗Reviewed less widely than Sofirn's headline models, so there's less independent data
Sofirn SC31 Pro
- ✓Full Anduril at one of the lowest prices it has ever been available on
- ✓USB-C charging and a lit side switch on a simple, robust 18650 body
- ✓Deeply configurable: ramp shape, thermal ceiling, mode memory and blinkies all adjustable
- ✓Good output for the money from the SST-40
- ✓Straightforward to live with once configured, and cheap enough to be a loaner
- ✗Cool, low-CRI SST-40 — colours look washed out next to a high-CRI light
- ✗Several reviewers found the beam pattern unremarkable
- ✗Scattered reports of early failures and flickering units
- ✗Anduril's configuration menus are intimidating if this is your first enthusiast light
- ✗No aux LEDs, so it's hard to find in a dark room
