The NEW Sofirn C8F Triple XP-L W2 w/side e-switch

After the initial fiasco with the first version of this light (without direct thermal path board LoL) they probably decided to play it safe with these higher Vf XP-L emitters, which have a nice tint btw.

Cheers ^:)

Just curious, can you elaborate about the “initial fiasco” without direct thermal path? Sorry I hadn’t read about it. So did the LEDs overheated and burned up without it?

See here: XXX-Man's Review and disassembly: Sofirn C8F

Cheers ( ͡ᵔ ͜ʖ ͡ᵔ)

Think they were triple XP-G3s on an Al board. Bright as all Hell, put a giggly schoolgril smirk on my mug when I first saw it, but if left on too long will, alas, cook the LEDs.

Fine for short bursts, but don’t leave it on for too long.

Think I got 3 of ’em before they were discontinued. :smiling_imp:

Oh, and tailswitch only, no sideswitch.

Hey guys, Sofirn is working on both a new light in the style of the L6/S70s as well as a new UI.

If you have suggestions on the UI or want to voice your opinion on what is currently suggested, check out this thread.

Are you a Sofirn troll now Jason?

Couldn’t you just post that in Kronological’s K70 group buy, the one that Sofirn is taking over? (already known there, of course)

This thread is about the C8, a MUCH smaller light, with interesting developments in the C8 lineage not the least of which are the triple reflector set-up and the e-switch. Please try to stay focused…

Yes, I am a Sofirn troll now. :confounded:

Actually there is more involved here than you think, but which I can’t speak about. People who are interested in the C8F should also be interested in the new UI. That is all I can say.

So I am going to certain threads about the C8F and SP32A to see if anyone would be interested in talking about the new UI Sofirn is making. Its not so much about the new light.

He’s not a troll :innocent:

He probably only wants to help ghost group buys out.

Back onto the main project, what I would absolutely love is the addition of an 21700 extension tube, or maybe an triple OP reflector.

That first one would make 10k lumens with XHP50.2s possible in the palm of a C8, although there would be a risk of the LEDs, even in a triple array, to be destroyed by 2S 21700s.

Yeah, I know Jason. Couldn’t resist though. lol

I have a Titanium X6 with a largish copper pill section fitted with 3 XHP-50.2’s and running 10,200 lumens via a pair of 18350 cells. Pretty amazing! The Aspire’s have the longest run time possible in this set up and don’t deliver maximum power so , so far, the emitters are intact. I’ve been thinking about doing it with a different light, figured more cell like in the C8 with an extension tube and a pair of 21700’s would probably blow the emitters. Fun though, seeing all that output from a handful of flashlight.

I initially built my DBC-05 for three 50’s, not knowing what they would do, and was not impressed with the output. Switched to 50.2’s when they released and still, only 11,000-12,000 lumens. So I rebuilt it with three 70.2’s. Crazy, that one! The pair of iJoy 21700’s did some 32A and melted the plastic housing of a mini Omten switch. Now with a Tofty, a pair of Samsung 30T’s do 48.8A at the tail and 20,000 lumens. It makes a LOT of heat!

Jason, see if you can get Sofirn to use the Samsung LH351D, that would be interesting…. I have had dealings with them too and they seem eager to please.

I even hear there’s a new XHP-35.2 out… :wink:

What! Are you pulling my leg?

Nope

Cool! I wonder what these bad boys can do in a BLF GT. Just swapped the sense resistor to bump up the output. :smiley:

As I understand it the gains on this one are minimal, I don’t know if it’ll be a good thing here, as in the XP-G3, so I wouldn’t get too excited about it until some testing can be done.

The GT was set to deliver optimal performance from the 35 in High, the double click to Turbo gave right at the peak performance before the fall off. Tweaking it for more power is just gaining heat, not output, and reducing the life of the emitter. This is one factory light that was set up by modders, there really wasn’t a lot that could be done by way of improvements as it was built in from the get go…

I was assuming the new 35.2 made its peak power at a higher amperage like the 50.2 and 70.2. Something like 3A to 3.5A. Alas, it does not seem so impressive.

I saw a number of 4% better lumens output to current draw, not really much at all but more efficient all the same. Until some folks get hands on experience there’s just really no way to know what the new 35 will do. Possibly more current, somewhat higher output, which would be fine, but at the same time the flip chip technology has shown us odd tint in the beam and less potential for throw… and they’re even more difficult to remove the dome from with good result.

Update: Here’s the announcement I got…

Enabled Sofirn c8f 18650 at room temperature (26C degrees) in 990Lm mode. After 20 minutes, the temperature of the head reached 58C degrees. Honestly I hoped that Sofirn would stop at 50C, but alas.

Anyway to get switch LED to stay on?

Without to much modding?

No. You would have to completely get rid of all battery indicator stuff and rewire the switch to the driver.

Hello guys,

Sorry for reviving this thread. I bought that flashlight Sofirn C8F on AliExpress a few years back. It worked OK, but light usually got less bright as battery charge dropped. I recently removed the battery to recharge and placed it back fully charged verified, but the flashlight no longer works, does not react on pressing the side button, and there’s no tail button like in new versions. Tried 2 other 18650 charged batteries - still doesn’t work.

Not sure what the model version is, it say SF18F262 on the front cap with glass. What has likely happen to it, any way to test, is there anything I can do to revive it? If the driver is burnt, why this happen at replacing the battery, and where to get the new driver, which driver model would you suggest?
