New Sofirn TIR thrower: IF22A SFT40 2100lm 629m

[Barry0892]

@derfyled

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.

I highly recommend you our new released flashlight Sofirn IF22A

This one generally meets all your needs

Here is the link! CLICK ME TO CHECK

You won't regret after buying it.

Any word on when the Reflector version IF22 will be in stock again? Only showing IF22a on sale and in stock on the Alixpress store today.

We are stick to IF22A TIR optic version first. Because according to our latest test results, IF22A even throws longer than IF22.

So if22 the reflector version probably a little more throw and much more spill right?

Much more uncontrolled spill. So reflector only gives a beam and a circle outside the beam, the tir kind of gives a smooth diffusion from the beam and out to make a decent near light plus a decent thrower. In this case it seems. Tir can be made in many different options.

So the tir version is better at dual purpose than the reflector version?

Seems like it from the few beamshots out there. Have not got mine yet but looking forward to test it out!

@Tendou

Which one will be a better thrower in real use? IF22A or IF22?

Reflector vs TIR in this case?

According to the latest test results, IF22A throw a little further. I don’t know why the previous results are different.

I think they are not much different. But if you pay attention to the beam, IF22A with TIR optic gives a beam more like thrower

Sofirn IF22A Review, SFT40, 2100 Lumens, (Drone Mounted Footage)

[Muto]

Gotta say just received this IF22A and it is a Beast!

Already have the Manker BLF MC13 and was not sure if this Sofirn would be more of the same or better as the head size and TIR appear to be the same.
However with the Sofirn you are getting the new SFT40 and it casts a way bigger badder beam as well as the flashlight shedding heat very well.
With the increased battery size runtimes will be better as well.

Anyway, really like the very compact size, it just glides into side pocket with nothing sharp edged.
Can’t wait to show it off to some friends that I’ll be visiting out of town on Monday night, she’s a keeper and a winner.

Later,
Keith

Just need to bypass the rear spring for an extra 2-300 lumens

Agreed … I am very pleased with my new IF22A.

Super light in all aspects.

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

[JaredM]

Depending on the type of TIR, a glass lens can really ding the overall efficiency of the optics.

I wonder if the rise in current is from the emitter heating up and Vf dropping. That’s usually not accompanied by rising output, but i suppose the change is subtle enough to be explained that way

[JaredM]

Do you have an EA01 with sst40 to compare optics and throw values? Or FF E01?

[pennzy]

Thanks for reporting Tom. I put some DC fix on mine for G&S. Not bad. Running it on high seems not to overheat. Plenty of flood with a little throw.

Well, I got a FF E01 w/SST-40 (not an EA01), but the TIR optic is different - you can see the LED, but the other differences like the smaller width optic in the E01, and SST-40 vs. SFT-40 has big differences in throw.

[JaredM]

I thought I remembered you having an ea01 or the mateminco equivalent… my bad.

I’ve been wondering how the FF might do with the SFT… how close to 100kcd it could hit. My assumption is 220% throw vs an old bin sst40. It oughta be much more pocketable than the if22a.

No, you are right! Just found it. :FACEPALM:

...

Could it be possible that as the battery heated up, that the battery's internal resistance decreased allowing a slightly higher voltage to deliver a little more current and increase the brightness before the voltage sag eventually caused the brightness to decrease?

[JaredM]

Not likely on this timescale at this current. The only thing with a ntc behaviors would be semiconductors. Either the led of fet.

@Tom E

No, you are right! Just found it. :person_facepalming:

If you get a chance, I’m curious how all three of these lights compare using the same lux meter and tested back to back.

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
