Review and disassembly: Sofirn C8F

:person_facepalming: I still haven’t received the first, self destructing version :smiley:

The new updated version of the C8F will be released November 8th I was told by Sofirn.

My C8T is a killer, 80.000cd just after switching to AR lens. I will post a review,just couldn’t find time lately.
Unbelievably this light have same size hotspot from 5 meters like UT02 which have much bigger reflector. :+1:

Jarl! I am also to post a C8T review pretty soon, with a freshly loaded 30Q cell I've been able to measure just above 6A at the tailcap with a custom built shunt.

Candela figures… don't really know what to say. I've measured up to 102.4Kcd but of course my smartphone's luxmeter may not be very accurate.

Stepdown time is ≈3:25 in my early sample, measured up to 52.8°C at the head fins just after stepdown.

Medium mode, handled via a low power MOSFET, should be PWM free but I haven't tried to check it out, may someone suggest some tool like an Android app? Can be from any source.

Cheers ^:)

I just sent a mail to visosystems and said that they should fix their flicker tester app for android.
Maybe it helps, you could always borrow someone’s iPhone and download the app to check the flicker.

Edit: Got an automatic mail back saying he’s not in office until Dec 3:d so better find someone who have a iPhone you could borrow…

Will the sorfin reflector fit on a Convoy c8?

C8F reflector won’t fit C8. It’s shorter.

Here is my review for C8T

The whole C8F thing is a different e-switch beast now, Tracy Wan agreed to send me a unit 4 days ago. Told her about its somewhat steep retail price. She told me it comes bundled with a high discharge cell, yet I can't find any claim in this regard in the selling page advertisement.

This is my published review of the C8T: Sofirn C8T premier review/test - Like!

Cheers ;-)

55$ no way ! I can grab 2 pcs Crelant V6CS with infinite brightness control for that price…

phew
I am glad that I got one for ~20$ :stuck_out_tongue:
a price between 30 and 35$ is what they should aim for.
the high discharge cell is not a reason to boost the price that much.
a 30Q is 5$ for end customers…

I bought the first c8f and immediately the leds quit working I’ve tried working it out with Cissy and Sofirn but they haven’t been easy to work with, I’m waiting on a response from her right now to see if at least they will refund my money but they haven’t acted very professional in my honest opinion. I would tell everyone to proceed with caution if you’re buying from them. I will update later as to the outcome.

Of course, the new C8F price is nuts. If this is because of hand-crafted custom parts I believe this is an error in this market segment. We'll see if they can fix this.

I really hope that isn't the cell bundled with the new C8F. :facepalm:

Cheers ^:)

P.S.: Andybibbville, at the very least ask them to send you a unit of the new triple MCPCB with XP-L leds, that way you can fix it up yourself or with minimal help from some soldering iron equipped friend.

Yes Barkuti I haven’t thought of that, thanks.

Genuine Sofire cell 9900mAh
I was gonna say 10,000mAh but we know that not possible.

In all seriousness, I just can't understand that C8T bundle. The C8T is pretty good, pulling up to just above 6A on a freshly charged Samsung 30Q. It does not bode well for that Sofire unless it is a genuine high discharge cell rewrapped by who knows who. Most ludicrous rewrap I've ever seen, at least if they aim to inspire confidence.

The only other 18650 on their site is this one: https://www.aliexpress.com/store/product/2-Pieces-High-Quality-2800MAh-18650-Battery-Rechargeable-3-7V-Li-ion-18650-Batteries-for-LED/2933049_32806585536.html

I wish they were to clearly state what OEM cell is under the wrap, but I guess whoever buys that just knows no better.

Cheers ^:)

The picture now shows 3000mah. These were tested to be a great cell. Equal to the 30Q in output.

So they must have upgraded it.

They might rewrap different cells with similar specs depending on supply, I once asked liitokala about the lii-35A, which says it’s a sanyo GA, but the flat top is identical do the samsung 35E. I wrote to them on 2 different email addresses they had listed on their site and each got me unmatching responses, one said 35E and the other GA, neither responded to my followup email

I checked capacity of the Sofirn 3000mAh button top that came with my new version C8F and it came out to 2850mAh.
Only tested once in a new to me charger the ZF C4. The C4 only Nor tests at 500ma so I charged it at 1A, then Nor test at 500ma to save some time.
Never had a 30Q below 3000mAh even at first test. The sofirn batt also gets 92-105mr Kinda high for a new battery??
