The 2022 model Sofirn IF22a is a compact Thrower flashlight that produces over 2000 lumens. It comes fitted with a Luminus SFT40 emitter. This is the domeless version of the SST40, but with increased performance. In summary, the IF22a has become my pocketable 'go-to' light for long-distance applications. This is a budget-friendly light with excellent build quality.

Sofirn provided me with this model for review. This flashlight kit came with the light, battery (Sofirn 5000mAh 21700 cell), spare o-rings, USB-C charging cable, 18650 cell spacer, lanyard and manual.

More importantly, while SST40 emitters produce a softer, more diffused beam, the SFT40 creates an intense hotspot capable of throwing up to 670 metres in the Sofirn IF22a. And this comes in a small flashlight that you can fit in your pocket!

the IF22a uses a TIR (total internal reflection) optic with a protective glass cover in order to achieve these impressive throw figures.

I found that using a Samsung 30/40T produced extra brightness/lux readings (+10-20 lux) in this light.

This is the only TIR light that I have in my collection and I was surprised at how intense the hotspot was. It out-throws all of my other lights besides the Imalent MR90 (SBT 90.2 emitter).

You can see the beam clearly, like a lightsaber on a dark night. The optic does a great job to contain most of the light to a narrow beam whilst also creating some usable spill. It's difficult to capture on camera, but that was important to me as I'm not into LEPs for daily carry due to their limited beam profile.

If you want a practical pocket thrower, this is it!
