Sofirn IF25A

DiscontinuedSofirn no longer makes this light; what dealers have left is the last of it. See Sofirn’s current lights.

Four SST-20 emitters on a 21700 cell, run by Anduril 2, gave the IF25A a wide high-CRI flood beam. It sat a little larger than Sofirn's other 21700 lights and sold at a modest price.

Beam profile

Flood, about 33° wide. Wide and even — light where you are, not where you're pointing.

What owners report

Sofirn IF25A/5 sources reviewed

A compact quad-emitter 21700 light running Anduril, and one of the better arguments that you don't need to spend much to get an enthusiast light. Owners describe the colour rendering as fantastic and the sheer versatility of output as the reason it stays in rotation — one reviewer with a collection of far more expensive lights said they could happily live with only this one.

The consistent criticism is the driver. Turbo and high step down quickly to around 750 lumens for thermal reasons, which is lower than competitors settle at, and several reviewers describe the driver as the weak part of an otherwise excellent host — good enough that people buy it specifically to modify. The 18650 adapter sleeve is also loose enough to rattle, which a strip of paper fixes.

Consistently praised

  • High-CRI quad output that owners describe as excellent colour rendering
  • Full Anduril, with the versatility that brings, at a budget price
  • Very compact and light for the output it produces
  • USB-C charging in-body with a 21700 included
  • Good enough as a host that modders buy it deliberately

Common complaints

  • Steps down to around 750 lumens quickly — lower sustained output than rivals
  • The driver is widely described as the weak point of the design
  • The 18650 adapter sleeve is loose and rattles unless padded
  • Gets hot fast on turbo, though thermal regulation handles it
  • Anduril's advanced menus are a lot if this is your first enthusiast light

Questions people ask

What sustained output can it actually hold?
Around 750 lumens after the initial step-down. The headline figure describes the first half-minute; the 750 is what you'll be using on any real task.
Can it run 18650 cells?
Yes, with the included adapter sleeve — but the sleeve is loose enough to move around. Owners pad it with a wrap of paper. A 21700 is the better cell anyway.
Is it worth modifying?
It's one of the more commonly modified budget lights precisely because the host is good and the driver isn't. If you don't want to open a light up, that same fact means you're buying its main limitation.
How is the tint?
Good — high CRI and generally well-liked, which is the main thing separating it from cheaper quads. It's a large part of why owners keep it despite the driver.
