What owners report

Sofirn IF22A

  • ✓Around 300 m of usable identification range from a pocketable body
  • ✓Excellent interface — moon and turbo shortcuts, lockout, momentary moon from lockout
  • ✓SFT-40 behind a TIR gives a clean pencil beam with little wasted spill
  • ✓Doubles as a power bank
  • ✓Performance per pound is the best in the catalog at this reach
  • ✗Runs hot — around 70°C — despite the stated thermal regulation
  • ✗Output oscillates during turbo and high rather than settling cleanly
  • ✗Some early units over-charged their cells; check voltage after the first charge
  • ✗Fussy about cells: unprotected flat-top 21700 or protected button-top 18650
  • ✗Cool, low-CRI SFT-40, which is the trade for the throw

Convoy L21B

  • ✓Around 1,300 m of measured ANSI throw — best in class at the price
  • ✓SFT-40-W domeless emitter that handles 10+ amps
  • ✓Capable 8-amp buck driver borrowed from a higher-end design
  • ✓Stable tailstand
  • ✓Convoy's informal but genuinely responsive parts-and-repair support
  • ✗Body texturing isn't aggressive — slippery in the wet
  • ✗Only a basic lanyard included for carry
  • ✗No charging, and cells with built-in charging won't fit
  • ✗Protected 21700s are too long
  • ✗Biscotti interface is basic compared with modern firmware
