Sofirn C8F host. 21700 C8F Available

Ugh. Reading back over other replies makes it clear to me that making a revision of the C8F for a larger battery opens a huge can of worms.

Better, I think, to do another rethink of the C8, like they did before, but this time, using the C8F as their point of reference. I’m guessing that using the same components in multiple lights is a win. That would either mean choosing parts from existing lights, or making a new part for a new light with plans to use it in future designs as well. Does anyone know if the C8F reflector is shared with Sofirn’s other triples? Judging by head diameters, it seems like it could bel

I don’t know why you think that. Same basic light, just bigger battery tube. Simple. :slight_smile:

I would buy both versions, but if it has to be one, better be 21700 - more portable with almost same capacity and also the new battery somehow triggers the interest. A version with onboard 2A charging might easily enlarge the customer base as people without collections of flashlights will just use the battery, that is coming with the light. Tailswitch should be included for lockout.

Oh yeah, put me down for wanting the 26650 battery tube.

I also want a rear switch, either stock or bought seperately. Just as long as it’s available. I like that type of lockout over turning the endcap. They could make extra money selling them seperate as well. :+1:

Maybe just stick the SP33 battery tube and end cap on the C8F. It has knurling and looks good.

I didn’t see anyone saying they need “big angry” knurling. Not looking to grate cheese or shred our Cardigan pockets. :stuck_out_tongue:

Just mildly aggressive will do fine.

Have you ever held a Thrunite? …Now that’s what I’m talkin’ about! :heart_eyes: :heart_eyes: :heart_eyes:

Definitely 26650. Girth is Good!!

21700 :+1:

This C8 looks different from other C8. How about the performance? A useful friend?

What do you mean? The sizes or the triple reflector?

Exterior and interior

Just counted the votes and the 21700 with dual switch is just a bit ahead of 26650 and single switch at the moment.
The other improvements and changes also counted but it is on Sofirn if they want to change things or not.

I think all your questions are already answered in this thread. Plus there are reviews of the stock light in the forum.

Is 21700 going to be a fad or do we think it will stick around?

I think it will be growing. There are some manufacturers coming out 21700 lights like Acebeam, Manker, Astrolux

It’s not so much the flashlight manufacturers I’m concerned about, it’s the battery companies. I don’t know much about the 21700 battery size. Is that size made by any of the major battery manufacturers? What are some of the best models in that size?

Panasonic is fully making the 21700 size but only for Tesla. (And Tesla are making them too but only for self use)
Other manufacturers are also making cells in the 21700 size. Most are going to be used en ev’s. Power Tool manufacturers are also using this new size. So I don’t see it disappearing for a while.

I found a few on IMRbatteries
And I found that article.

This thread is a useful can of worms, it will be great if Sofirn comes up with a new light that has a couple of improvements over their current C8F. I would be concerned about the multitude of opinions if they were directly vented to the manufacturer, but with ZozzV6 as the middle man it is no problem. :slight_smile:

Thank you! I like more options and want to push things that way to make happy the most people.
I like the way convoy do this.
I have an idea that If somebody want to build a light not buy complete host. The basic host will be the head and tube and reflector. Then separately you can buy switch tailcap or switchless and MCPCB for XM or XP size leds with the specific centering rings. Or something like this. It depends on them how much they will want to sell the host in parts.

Ah, so they are not as great as I thought. You can get 4800mah capacity, but only 10A continous output or 3000mah capacity and 35A continous output. It just depends on the particular chemical mix they are using. Just like 18650 cells. They really don’t seem to compare to the 26650 which has a good compromise between the two.

But they seem good if you need high capacity in a small light as long as 10A is enough.

It also seems good if you need really high amperage, but don’t need high capacity.
