Sofirn C8F host. 21700 C8F Available

Did a quick search but didn’t find anything.

Did anyone mod this light with 3x sst-40 using a fet driver or other high performance driver?
If so, how much lumens did you got?

C8F has arrived! Here is my build. It is nice that it came without any engraving.

Yeah received yesterday unbranded host, quite heavy for a C8
I am not sure if I like the smooth host, a bit knurling would have been nice

I wish there would be a transparent switch cover included for lighted switch board, but I will look into it later if I can find a solution

Yeah, their hosts are unbranded. I love that they did that. My regular Sofirn C8 is the same way. Kinda wish Convoy did that.

Hello friend! Began to collect a flashlight sent from Sofirn and found that the electronic button does not have a free wheeling and is not pressed. That is, it stands in one, jammed position. What to do ? Where to buy a similar button? Maybe she understands? I wrote to the seller, I’ll see what answers.

That is some fine machining johnkey! Those switches can be found easily, I’m on my phone now but I will get you a link later.
Why did you choose for a TIR optic?

Experiments. Boredom. :innocent:

:cool: That is sound flashaholic reasoning. :smiley:
Nice line-up!

Wrote about the problem in the shop Sofirn on Ali.
Already sent and given a track number.
Simply good fellows!

Still found ….

I don’t understand:
Why would anyone want to replace the Sofirn triple LED PCB with a Noctigon?
Both are copper DTP.

I can understand going to the Noctigon for it’s 3 oz copper traces, have no idea why the awesome reflector was cut into a spacer in favor of the boring CUTE-3 optics though. The triple reflector is what makes the Sofirn a game changer. Much tighter beam from the reflector. But then, I’ve built so many dozens of CUTE-3 optic triples…

Just goes to show, different strokes for different folks!

Can someone recommend me a driver and mcpcb for 3 xpl hi configuration?
Btw do I need to by extra centering rings for the emitters?
What’s about the lense, is it anti reflective?

Here is my build.
I think lense is plain glass.

Which mcpcb?

Stock, it came with a host.

I am waiting on my C8F kits (bought TWO) and I'm a newbie-- but I have had great help from several dudes here.

I also was wondering about a driver, but after chatting with Lexel... given my 30Q batteries (and other good high drain batteries available) AND using (3) XP-L2 LEDs (bought from Arrow last week), this light can run true direct drive using just the rear switch (and get a draw of about 12-14 amps into these three LEDs- a nice fit!). I maybe should have gone with XPL-HI LEDs for my application (hunting = throw needed), but I'm going to try the XP-L2 for now and "see" what I get for my pig hunting rig (as I don't shoot pigs past 150 yards anyway).

Lexel sells a cool little C8 "FET tail switch board" (to use with a pressure switch of your choice) for a hunting rig. I am using these for my "Pig Rig" (my 6.8 SPC rifle I shoot pigs with at night) where there is NO loss (not even drain loss) and FULL output is the result (since higher current lights otherwise lose a LOT taking the trip down the 16" or thinner wire and back on your run-of-the-mill pressure switches out there).

So my "Rev A" plan (was)... Use these FET tailboards as my ONLY switch in my C8Fs and going DD (Direct Drive). I WAS originally building for hunting ONLY-- as I wanted NO modes- just FULL on and FULL off for hunting.

But... I was ALSO JUST told by Lexel (nice guy, I ask him way too many questions- poor guy ) that I can ALSO use his Narsil driver too. This driver can be set-up for ONE mode (on and off) or run other modes. I thought it through and going with this driver is probably a better option to running pure DD... especially if you want some protection features for the batteries. Lexel said I can hunt with his FET pressure switch (using just the on/off full Turbo mode), but when done hunting- replace the original rear switch (going back to stock) and THEN... this C8F with his Narsil driver would ALSO work with the side switch (in any mode). :THUMBS-UP:

So I'm now going to buy a pair of Lexel's drivers as they will give me a light that will be useful to me the other 10 months of the year I am not pig hunting ;).

All I have to do is build a few tail switches (I have the FET boards, just waiting on the C8Fs kits so I can get started) and I can use the ones that come with the kit, OR buy a spare tail switch or two (or in my case, I HOPE to use the spare C8s tail switches in my spare parts drawer for the FET mods-- but have to see IF THEY FIT this C8F first!) Come on Sofirn Boat! FULL speed ahead please!

Interesting read, not quite sure how you’ll be putting tail switches in the side-switch equipped C8F. There’s only a flat pcb with a spring on it in the ones I have, no room for a tail switch to be added without using a different tail cap. Curious to see how you proceed.

I tailstanded the empty L2 host in a bowl what has a little water in it about half tailcap high to keep the black end cool. And then used blowtorch to heat the bezel side.

I’d be lying if I said I knew what I was REALLY doing here :wink:

I’ve read ALL your posts on this light Dale, and they have been super helpful to a newbie like me. Truthfully, I’m going mostly on what Lexel is telling me will work for this config. As I read that he just got a C8F in recently… I assume he’s got me in good hands. But I’ll ask him about the tail cap room for sure.

One thing that I am learning is that the C8 “standard” is kinda iffy when it comes to different makers. I started off buying the eBay stuff (and was surprised at the quality of several C8 styled lights I’ve gotten over the years). My headlamp is going strong after 4 years at $14 shipped then— uses a C8 head, reflector and decent glass.

Anyway, I JUST ordered a KDlitker C8.2 in the 2600 lumen (med-white) model- GREAT little light BTW. But when I went to use my (generic) C8 tails switches I had off another light (Convoy, I think) the tail caps didn’t threat— what??? I thought ALL C8s had the SAME specs :person_facepalming:

So learning the hard way I guess… and peeing on the electric fence a few times as I go :confounded:

The stock switch cover is semi-transparent like on the GT.
You can replace the tube with Convoy. It is fully compatible.
Lexel can you make an Emisar D4-D1-like FET+1x7135 driver design in multiple diamters for E-switch flashlights? I will be happy with a 17mm which will be great for this host and one that fit a Skilhunt H03.
It would be great!
