Interesting. I hope he’s going to focus on producing something that’s not a pocket hotrod but instead something that will manage heat well and provide a reasonably sustained high level output.
Isn’t the SFT-40 just a dedomed SST-40? The latter is available in 5000K so it would follow that the former should be too.
It is not! 
Gives quite more lumens per watt, same for candela. Seems like a different beast! Look at the rundown of the led on this site!
thank you Lumen9000.
@ bcm00re- it defintely is not. It handles more amps, is brighter, has higher luminance, and is overall just a better thrower led in every way. It is definitely the version2.0 of the sst40. A dedomed sst40 will see an approximate 20-25% decrease in output and the same 20% increase in throw. The sft40 sees a increase in both output and throw, with throw exceeding far beyond a 20% gain over sst40.
for official bench test and awesomeness - see djozz's test here on BLF. For physical ( and mediocre photographed IMO) beam shots, rake a look at the tag in my signature line. And look at post #7 for the comparisons for color, abd you'll see why I'm so excited about a 5000k sft40. This led is almost perfect in my book (throws "like" a sbt90 but without all the heat, because it only needs 1/2 or less of the amps) but the one thing it's missing is a lower cct option.
Thanks for setting me straight you two! I guess I remembered the part where djozz said, “Luminus SFT40 is like the dedomed version of the SST40” but not all the rest. 
We never stop to learn!
That’s why I’m so interested in a thrower with the sft 40, it might be quite effective for its output, making it last a couple of hours but still with good throw, and with this TIR, it seems the “bleed” gives quite a good light outside the focused beam.
haha, thanks for reading my rant! i apologize, i just have been very excited abut this LED since getting them in, i have put them in about 8-10 lights. It is just such a solid performer and exciting that it is 3volts, now with the word of 5000k, it really just completes the "line" for this LED. It will be really hard to beat this one once it has a 5000k options, except for the fact that it may be pretty hard to get. if the last 2 months have shown us anything with them only being in stock for a week or two.
IF22A/IF22 restock , order now with discount price and could use code :5XD4VLM0HKFP 
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.
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.
We are stick to IF22A TIR optic version first. Because according to our latest test results, IF22A even throws longer than IF22.
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!
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
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,

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
