Check and see if your spring bypass is still secure too. Could it be triggering the battery protection (you said laptop pull) when a loose bypass wire makes connection with less resistance (on either end really)

This light is made to accept the non-anodized threads into the head of the light. Anodized threads at the tail cap. Without having pictures of the actual arrangement of the wires and such, it’s just impossible to predict what the problem might be. The simplest and easiest to make mistake is to reassemble with the battery tube inverted, causing contact issues. Other than that, there shouldn’t be any issue if all the contacts are made properly.

Keeping the wires long from the MCPCB allows the light to be assembled, but they need to be cut off just long enough to solder onto the driver, this will prevent an excess of wires in the driver bay. Done this way, even 18ga wires will work…

I will have to check. I remember having the non anodized threads at the head. That is why I kept the tube unscrewed at the head, I figured the tail cap had to be on tight to make contact. The light does light, just not when the head threads are tightened up. I remember a previous thread somewhere about this happening and if I remember right the springs were pushing so hard on the battery that it deformed the battery causing loss of current. I’m not sure why this would happen as I haven’t done any modification of the tube or cap.

Can you explain a little more how this would happen and how it triggers protection? To me if the bypass is loose there would still be current flow through the spring.

The bypass would not affect operation, and you clearly stated that you were using a flat top cell pulled from a laptop battery pack, no protection circuit on these. They tend to not be the most capable cell out there, but should still work fine even if not making as much output as a top cell.

Thank you Dale. I am following in your footsteps with a UV light build in this nice host. Will post details if I can get the thing working right. I wanted to start slow with a cruddy battery since I am not quite sure how the emitters will handle full power.

UV emitters are typically much lower voltage/current, like 700mW or 1000mW, so if you aren’t taking precaution to keep power level to their requirements you’re gonna blow 3 UV emitters in a big hurry.

While we’re on the subject, what current do you think the Sofirn driver puts out with an average battery for the C8F, no DB Custom FET mods?

I reviewed one of these and I am in contact with Dale comparing notes a lot of times also.
with everything as the light comes out of the box , I would say 8.5 to 9.5 amps would be a good average to expect from the included cell or a quality high drain cell.

Thanks Robo. I am assuming that is on Turbo.

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?

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?

Cool That is sound flashaholic reasoning. Big Smile

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?

I think lense is plain glass.

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 foot-in-mouth) 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!laughing
