Sofirn C8F host. 21700 C8F Available

Great host!

Yesterday I finished mine

3x XPL-HI V3 3C 5000k
FET+1 driver with bypassed spring and flashed with a e-switch ramping firmware from toykeeper

It pulls out 3000lm at start and +66000cd (513m)

We feel so sorry that the parcel on 11.11 did not arrived yet. We will refund or replacement for you. Please feel free to contact us on Aliexpress.

As we all known, shipment is vital in business. However, honestly speaking, sometime the shipment is out of control in some degree especially around 11.11. We could not image that millions of parcels shipped out everyday from 11.11 to 31.11. Some parcels stopped or lost in delivery. All sellers push and push and push and push the carriers to check the reasons, but the results are not always good or expected. Generally speaking, we would like to make replacement or refund for our customers because we want to make it right. What’s pity, we are not able to make a good compensation for customers’ waste time or feelings, who eagerly waits for months but the parcel delayed or lost in delivery.

Highly appreciated for your understanding. And please feel free to contact us with your order ID on Aliexpress, refund or replacement.

Hope you enjoy all purchase on Aliexpress.

Same thing but I got 50% refund, proof that package really had only one bezel was 25g shipping weight on CN22 declaration.

Yeah. I can confirm the modus of this seller from AliExpress. Seller falsely advertises 2 pieces for the price of 1, but seller sends only 1 piece. When confronted about it or when protest is filed, seller claims mistake or error in the title of their ads. Whether or not it was intentional, do not tolerate this practice. Make a complaint and ask for a refund. Avoid these cheating sellers in Ali, the one mentioned by ZozzV6 in particular.

Same here. I tried to work it out with the vendor directly, but the vendor kept being slippery. I finally disputed it and asked for a 50% refund. Then the vendor offered to send me the other bezel if I first close the dispute for "personal reasons". Waiting for final resolution from AE.

I hope you don’t fall for that. Once you close the dispute, AE might see the issue as resolved. Also, you have no assurance that the seller will honor his word.

Same here, I recently bought a Convoy C8 and also decided to use it’s tube and tail for the same reasons. Also installed the Convoy SS bezel. Now I have a Sofvoy C8F!

Dale, this may have been brought up already, was this statement you posted way earlier in this thread a mistake? (post #81) I only see the C8A with XP-L2.

This was pointed out in another thread and I wanted to clear up any confusion, including my own.

Are you asking about the early version of the C8F?

It had no side switch. Had the aluminum mcpcb. Had xpg3’s. Had a rear tail switch.

They don’t sell that version anymore as they tended to burn up the emitters.

They redesigned it to what you see today. I wish they had changed the name to signify the difference, but they are both called the C8F. Hopefully everyone will forget about the first version.

No I’m not asking about the C8F v1 (I have both v1 & v2)

My question for Dale was for his statement (I put in bold and underline) in his earlier post (post#81) where he stated that the “NEW” C8F comes with XP-L2’s. But as far as I know it didn’t, only regular XPL. Unless I missed something.

.

I’ll edit out the first part of his quote in my post to avoid this kind of confusion in what I’m asking about.

Oh. Okay.

Yeah, Dale made a mistake in saying that. It comes with xpl’s.

I’m sure he’ll be a long soon to give more details.

See his review over here.

Just FYI I have the XPL2’s in mine as well (built from a host, not from Sofrin) and the few hundred lumens increase comes with a yellow corona trade off. You aren’t missing anything unless all you care about is MORE POWER!!

Did you swap to a better quality FET to get even more output? The one Sofrin uses is not so efficient.

It’s a MTN fet+1

Doh. :person_facepalming:

The host does not come with driver. I forgot.

I am still a novice when it comes to building lights (so far built a 85cri-nw with Convoy S2+ and a cyan with Convoy M1). I am in the middle of building a triple r9080sw45 219b (thanks clemence!) using this host. I plan to run it at a conservative 2A (I hate turbo modes and my country has warm climate), and the experience so far has been daunting.

I couldn’t use Sofirn’s fet driver as the current would be too high. So I thought I would go with a Nanjg 105C. Could not afford a Pomona soic clip, so hand soldered the attiny and flashed momentary star firmware with some modifications. Now the thick driver retaining ring of this host refuses to fit over (the 2x7135 heatsink tabs on the backside of the driver obstruct the ring). So I must manage this somehow using excess solder. And the spring of the 105C is too short, so I have to buy some new springs :(.

The light engine part is complete though, but that was not easy either. For that I first reflowed the 219s to the dtp board, then attached wires, then screwed on the reflector to the board (this must not be too tight), then applied arctic alumina to the pill, then pushed the reflector-dtp-wires assembly inside (making sure the wires come out properly through the holes to the other side), then tightened the bezel and finally screwed on the center screw (this must be tight for good thermal transfer) going through thr reflector.

What are you doing? You keep bringing this thread up to the top of the list with this post why?

How would that be possible with only 2 posts? ??? I don’t understand.

That’s why I asked, “what are you doing”?

Unless there was a glitch in the system? Kept coming up as a new post? I read the same post 4-5 times and refreshed in between by hitting Recent Posts….

With only one post in this thread...

Maybe t18d16 keeps on editing their post?
