New Sofirn TIR thrower: IF22A SFT40 2100lm 629m

[SammysHP]

@Tom E

I just took some #’s on the IF22A and got:

• on a 40T1 (old rev, better) at 4.18V: 9.0 amps w/tailcap removed

• lumens: 1730 at start, 1740 at 10s, 1680 at 30s

• throw: 113 kcd (772 meters)

The initial rise in amps is interesting. I’ve only seen this with higher resistance springs, but I seen the rise with a jumper on the batt- to tube, so eliminating the one spring in the tail. There must be something else in the circuit that reduces resistance as it heats up initially, and confirmed a bypass on the tail spring will boost amps, boosting lumens and kcd.

The lens appears to be uncoated, so it may be possible to get a 5% or so bump by replacing it with a double coated AR. I say “may be” because it’s hard to judge the quality of the glass used.

Lens size: 23.5 mm x 1.94 mm

MCPCB size: 23.5 mm

I’ve noticed the same in my stock IF22, even at lower levels:

(Turbo might be cut off slightly because I’ve moved the light quite a bit when pressing the button so I’ve cut off the first 1-3 seconds.)

Ok, I’m not sure of the point, but:

FF E01 SST-40 5700K, stock except running A2, on a 40T @4.21V:

at 5 secs, 5 meters: 49 kcd
MT01/EA01 SST-40 5000K, A2, tail 20 AWG bypass on a 26800 @4.21V:

at 5 secs, 5 meters: 85 kcd
IF22A SFT-40 6500K, tail 20 AWG bypass on a 40T @4.21V:

at 5 secs, 5 meters: 116 kcd

MT01 w/IF22A optic: 73 kcd - beam looks softer, hot spot not as well defined.

(same 5 sec delay, at 5 meters, same cells as-is, not re-charged)

Thanks Tom. I was interested in the differences between the two larger optics… basically the question if they are identical or not… and what the throw ratio was stepping down to the E01. It’s a rare light and not many reviews or posts talk about it, so I wanted a head to head comparison. So thank you!

What this suggests, thanks to your extra testing with swapping the optics around, is that we can expect mid-high 70s kcd for the E01 with an SFT40. I think this is a sweet spot of sorts for maximum throw while staying quite pocketable. Above 34mm head really isn’t comfortable, at least for me as a slender person who wears Levi 511’s. YMMV

I don’t think you’d mistake the two

I’m on the hunt for a pocket thrower but there is so many options these days…

In this format (or smaller), what is actually the best thrower ? Ideally available in high cri or neutral white.

@Lux-Perpetua

According to Luminus‘s datasheet, SFT-40 will also be offered in 5000K. So far, 6500K is the only option available to order.

I would buy the TIR one if was available with the 5000K emitter.

+1 for 5000K
any word of these being available? i’m looking to switch from my C8+ (XPL HI U6-4C 4200-4500K) which i do love, to a 21700 thrower with internal charging.

come on sofirn! i love my IF22A for close work, as well as my LT1 :+1:

do folks hate the font, or where it comes from? i actually like the way the font looks. easy to read. don’t care for the source though. :smiling_imp: :person_facepalming:

The stereotype is that most people online hate Comic Sans as a font.

I don't know how true that is, though.

perhaps a poll thread is in order? :p

It’s always grossly overused as a “homey” or “handwritten” font, done to death.

I noticed the other day that Sofirn has released the IF22A in colors. Green, red, and purple. Available on ali. On Amazon US I see they put placeholders but they aren’t available for sale there yet.

Can’t seem to scrub the “US” part of the ali link again but it should redirect for those in other countries: https://www.aliexpress.us/item/3256804680053526.html
