What owners report
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
Sofirn SP40
- ✓Magnetic base turns it into a stick-anywhere work light off the headband
- ✓Aircraft-grade aluminium with machining quality well beyond the price
- ✓Four genuinely useful brightness levels, with a very bright 1,200 lumen turbo
- ✓Headband comfort improved over earlier Sofirn models
- ✓Long-standing reputation as the best-value 18650 headlamp with onboard charging
- ✗Micro-USB charging rather than USB-C — the clearest sign of its age
- ✗Output is unregulated and tracks the cell voltage down
- ✗No strobe or SOS mode at all
- ✗The head strap is thinner than premium brands'
- ✗Superseded by newer Sofirn headlamps with USB-C and better emitters
