Only 2,74 on a 18650 cell.
Would be nice if someone would measure with IMR cells

Re: Advance payment for limited SF-III run. ENDED!
the amp measurement refers to the output of the LED (or more correctly, the amount of electricity driving the emitter), correct? Sorry for the dumb question, just trying to keep 'amps' and 'volts' separate in my head. An electrical engineer I am not, I just like bright lights!

Mike, just received both flashlights, as usual i stand in awe of ur work mate! I am now the proud owner of 4 SFIII's folks and i must admit that there is nothing else out there that even comes close, so for those on the fence in his latest run, take the dive and rest assured as to the absolute quality this man produces :twothumbs
BTW for those interested, i measure 3.5amp at the tail off a 18650 IMR

Is that safe for the led 3,5A ?
Waiting for my newly ordrers AW IMR'S to come

Re: Advance payment for limited SF-III run. ENDED!
What is really recommended to use as power source here?
I use 2 x 16340 IMR, but would perhaps preffer an 18650. With a draw of 3,5A it should be safe to use an 18650 li-ion? Is an IMR just safer or does it have other advantages.
I took 2 cells to raise the voltage, my runtime is 16 minutes on high with an unscientific method of just switching it on, take it in hands and wait.
So, the real question is, how is the light regulated and what behavious does the light show with the different cells?

Re: Advance payment for limited SF-III run. ENDED!
informed Mike of my results, 3.5 amp with the combat grip and 2.7amp with the regular grip. Mike puts it down to a low vf led in the combat grip, has ok'd the use of IMR but does recommend regular AW batts. i swapped out the IMR and replaced it with a regular AW and the draw went down to 2.7 amp. not sure i will keep it that way as the IMR gives me the brightest beam i have ever seen:thumbsup:

Note taken - First thing to do in the evening - Measure draw of SF-III! Should be 1,35A or more with 2 x IMR 16340...

Hi Metatron,
Did you use two AW IMR 16340's or one AW IMR 18650? I've tried two 16340's in my SF-III and they result in a brighter beam than just one regular AW 18650. I've ordered a AW IMR 18650 to check if there will be any difference compared to the regular 18650 but it hasn't arrived yet.
Btw, I agree with your assessment 100%, the SF-III is in a class by itself and everybody should own one (or four, you lucky :devil: ).
Take care
K

I'm not Metatron, bus as he writes in post #706 that he used an 18650 IMR...
That's interesting, that it is brighter with 2 x IMR 16340. I never tried an 18650 li-ion because I thought I wouldn't notice the difference in the brightness with my eyes, I find that more than difficult if it isn't a huge difference to watch at a bright beam, change cells , watch again and judge whether it's brighter or not. I have no possibility to check outside in the real dark, that's easier of course.
Yeah, the SF-III with the Ostar SMT is really a class of its own, my brightest light (my limit in size is 2 x 123) by far, real nice beam with a huge hotspot and very much usable spill. You must see it to believe it, I can't wait to take it out to a dark forest! :twothumbs

Re: Advance payment for limited SF-III run. ENDED!
As is always my test for flashlights, I was out in the back yard with my dog last night, with all of the outdoor lights off. I had an aspheric 3D sst50 and the SF-III with me. My dog obviosuly heard something, and started going a little nutty by the fenceline, maybe 75-100 feet away. The SF-III on high imemdiately put out a well balanced fantastic area of light of the whole yard, with the spot big and bright enough to illuminate her and the field on the other side of the fence, where she was spotting. Nothing there that I could see, in one quick swipe of the perfect beam, though I got hints of eye-shine out a good deal further. What an amazing light!!!! Once again, I am humbled by Mike's creation!!
Now, the tree line past the field, at about 350 or 400 feet, the aspheric sst50 on tightest focus was able to put bright focus light on target, and showed not just the eyes, but the whole body of a coyote. Of course, no one expects that kind of throw out of the SF-III, but it was nice to have!!
The SF-III has caused this dedicated primary fiend to look into 18650's for the first time ever!! (Ordered them yesterday!!) I use this light too much to burn through all those primaries!!

Re: Advance payment for limited SF-III run. ENDED!
Thanks Henk Lu, I missed that.
I think that the difference is quite noticeable, not only to me but also to my wife. That is not to say that it's not bright on an 18650, it is, but it's even brighter on a two IMR's. :twothumbs Btw, my Mega Micro P7 is also noticeably brighter with an IMR than with the regular AW 123.
I can't wait to see how it works with an IMR 18650. Hopefully it is as bright as with two IMR 1640's. I'd prefer to use the 18650 because of its capacity and because it might be safer that way :thinking:
Cheers

Re: Advance payment for limited SF-III run. ENDED!
I just measured the draw on 2 x 16340 IMR : Just below 1,4A. That looks quite normal.
Than I took an 18650 li-ion (same voltage than the IMRS 4,10V) and to my surprise the draw went up to 3,4A! It stabilized after a few seconds at 3,2A.
The brightness looks the same to me, but as I said, I give no guarantee on that...

Re: Advance payment for limited SF-III run. ENDED!
My SFIII arrived today. Very nice, so small. The hotspot is indeed very intense, it reminds me of the hotspot from Surefire's latest optic, but with more and smoother flood. I'd say it's a keeper.
Runtime. . .
I just tried running it on two fresh surefire primaries on Hi. After eight minutes (8!) it dropped down to low. I was not expecting this. My MegaMicro on one primary gives around 25 minutes and then dims slowly, so I was expecting about the same from this light on two 123As.
Did it drop that quickly because of thermal protection? Would I get better results if I was holding it?
Mike, is that what you expect to happen on primaries?

18650 IMR i get 3.7 amp stable.
with 2 IMR's rcr123's i get a reading of 1.4amp

Hm, I don't no more about electric than some basis theory, but don't our readings state that it's better to use 2 cells?
The basic says V x A = W, so, if A goes up, it would mean that V goes down, doesn't it? I can't verify this, you'd have to measure the voltage under low. That would also be normal battery behaviour, the higher the draw, the more the voltage drops.
Unfortunately, 2 cells have significantly less capacity than an 18650, so runtimes are quite low. There's still no confirmation on the brightness, if the light falls out of regulation at a certain voltage, it surely is true at some point...
