Sofirn C8 Quick Review

Any chance you could measure the spacing of the reflector? I’d like to know if it is compatible with any Noctigon triple MCPCBs. Also, would the triple reflector work in a Convoy C8 host?

Nope, much better… I can actually see what you are referring to now. Thanks.

To Barkuti:

I crushed my LEDs when re-assembled C8F!!! :rage: :person_facepalming: . Will post pictures tomorrow ….

No, I didn’t request anything special, just paid and it came like that.

To What_are_birds”:

Will try my best and post pictures tomorrow.

Just by looking at the picture of the triple MCPCB, I'd say the distance from the emitter centers to the MCPCB center is ≈8.75mm. With this in mind, the emitters would be at ≈12.3744mm from each other center to center (equilateral triangle side lenght).

kotobuki, :facepalm: ouch!

Well, if you're daring it may be a nice oportunity to reflow some more to your liking emitters. Do some math if choosing low Vf ones. If not, I'm pretty sure Sofirn/ThorFire can provide you with a new triple board for cheap.

Take care.

Cheers ^:)

Thanks Barkuti,
But I have only few XPG2 LEDs around here, I may reflow them into MPCB to get Sofirn C8F alive !
Will buy some XPL2 for next mod …
:smiley:

Barkuti: So am I right to say Thorfire C8S is made by Sofirn? Sure seems like it.

If so are other Thorfires too?

I add some photos of C8A also. It had also spring bypass in driver but like always I over react and made my own thicker too :wink: I don’t remember seeing it in switch spring. BTW: Also in host comes screws to attach led board in place.

You’re welcome Jason :slight_smile: Thanks vestureofblood :slight_smile:

Jouna, I believe both ThorFire and Sofirn are products from the same OEM with minor aesthetic differences. Examples: Sofirn SF30 and ThorFire TA13, Sofirn SF31 and ThorFire VG15S, etc.

kotobuki, if you are to reflow XP-L2 emitters on that triple you may aswell stack solder another 8-pin SOIC MOSFET on the driver and cream the Emisar D4's output records with the help of a Sony VTC5A or the newer Vapcell INR18650 2000mAh. LoL! :-D

Cheers ^:)

Ok, thanks Barkuti. Sofirn has a factory and CNC machines and Cissy has given me info that they do all of their ledlights by them selves. Maybe they do for Thorfire also. Doesn’t matter to me but knowledge is power :laughing: :wink:

Some more pictures (I did reflow new XPG2 on MPCB):

Test with XP-G2:

:beer:

That’s a pretty good idea, thanks.
:+1:

Yeah but lets avoid dropping another clanger kotobuki, you recently had some that's enough. Lets first make sure what is the lettering over that 8-pin chip and go Google it, can you help? I'll do it anyway once I get my C8T.

Cheers :-)

As your service, sir:

“”9926A”“:http://www.vishay.com/docs/68606/si9926cd.pdf

Cheers :smiley:

Thanks for all the in-depth info and pics! One thing I was wondering, does a Convoy C8 battery tube screw into the C8F head?

Thanks for your idea:

:slight_smile:

Nice! That looks pretty cool all mixed and matched! :slight_smile:

I have a few 9926A dual n-channel MOSFETs lying around, not yet unsoldered off broken powerbank PCBs. These:

Banggood is a bunch of @#$%, I have been forced to view the source code of the page to be able to access the image links. Makes hot linking their stuff pictures much harder, at least if you're using Chrome browser. JavaScript related crap.

Ranting aside, according to @#$% datasheet the 9926A MOSFET features… (edited all of this useless information). This means the combined dual channel resistance won't go much above 20ish mΩ even with a semi-drained cell on a hot flashlight.

Cheers

User AnhTran has a little Nichia 219C 5000K R9050 sale going on, just saw his last message.

Cheers ^:)

By curiosity; how much amps/ watts does that stack solder add?
