I wonder if this is forward or reverse clicky.

It’s a moot point (unless you plan to swap drivers).

It’s probably Sofirns existing C8 tail cap which I think is reverse clicky.

Doh! Yeah, that’s it. But then I don’t think that’s FC.

Maybe the TK18? Something new I got very recently…

Think if I ever have kids, I’ll just name them George, George, George, and George. Less confusion that way…

Insanely fresh info about tailcap switch:
Just read my message from Sofirn Smile
The tail switch will be forward clicky. If the light is on, you can press and hold the side switch to stand-by mode or click the tail switch to cut off. If you need lockout, press tail switch.

The SP32A is side E-switch only. You mean SP31.

BTW Sofirn came up with the SP32A 2.0 version with temperature regulated modes and also 3 minute turbo timer. Revised firmware and battery level indicator in the side switch. And it has two new color option.
Today they sent me a sample for test and make a review.

Sweet! I once suggested to Sofirn to consider clear anodizing / silver versions. I wonder if that had any influence on this light. Looking forward to your review!

Dual Switch.
You gotta be kidding me

I don’t understand, why a dual switch is to be preferred to a only-side switch-light. You always have to switch the light in your hand if you want to make it on or off or change the modes.
I just don’t get it and I never will.
The Convoy L6 – fantastic light that get’s raped by the tailswitch.
Sofirn C8F – Only Side-Switch – a fantastic light and perfect experience.

I agree that a dual switch is quite the pain in the ass. I mean for just around the house or garden type work I know them to be just fine. For my pocket light I prefer a forward tail clicky. Three modes, with memory, and I am a happy camper. I know I will probably be hung up and shot but that’s okay. I just prefer it that way. I still have tons of different lights and use them often but, when I head out with only one flashlight on me. It’s a 3 mode froward tail clicky with no blinky’s in my way.

Shine on my friends. BTW, I love the C8F and am looking forward to the new one. Side switch, tail switch, or dual switch, I could care less. Sofirn knocked it out of the park when they came up with this light and I will buy as many as the wife will allow when the new one comes out. As long as it’s not 3000k with some abstract emitter at 98.35478CRI.

I ordered the SP32A v2 earlier. I debated whether to order another C8F host with it. I decided against it to wait for the 21700 version. It sounds like it will be a bit of a wait, still.

Zozzv6. Any word on whether they’ll be using the same reflector, or at least the same emitter spacing?

This non-political signature is not non-political.

Is the V2 ready for order now? I checked last week and it wasn’t listed yet. I shall check again.

Sofirn is bot an old vrand so they are not a very big factory. Please be patient. Just see a BLF project. It will be happen faster Wink No word on emitter spacing but I will ask. I think it is the same.

Yes. So tailcap switch is only a lockout.

I can not wait to see when the new C8 Host will be on sale
I’ll take two or three hosts at once
One host will go under NOCTIGON 4XP 33MM and LH351D
Already ordered a dozen LH351D 4000k 90CRI
Also on the road NOCTIGON 4XP 33MM 4P QUAD LED COPPER MCPCB and LEDIL ANGIE-S QUAD LED OPTIC

Wait for LED4Power to come out with his 6 led board with Anna6 optic. I want to see what you do with that Smile

I’m not in a rush. I know it will be done when its done. I’m just figuring out what to do in the meantime. I have four hosts, along with 4-5 lights I bought to mod (along with a Q8 on the way), and a few existing mods I want to revise — I have plenty of other things to do :). I think the first step is assembling some drivers to use :).

I’m guessing the emitter spacing will be the same, too. It looks to me like they’ve used the same reflector in one of their dive lights, and I’m guessing they’d also want to use an existing part for this update, unless there was a really good version not to.

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.

Man I can’t believe it took me this long to read about this C8F host. I’ve been waiting for Convoy to come out with a triple C8 for years!!! I read 90% of the posts in here and decided I’m buying one of these hosts from RMM (mtnelectronics) right away (like right meow).

Build list:

  • C8F Host
  • MTN-17DDm FET + 7135 Driver – 17mm (D4 UI v2)
  • Samsung 30Q
  • XP-L V6… XP-L HI V3… or XP-L2 V6 Evil

Sorry, been sick.

18ga wires will fit in the C8F, it’s just not easy. I gave the C8F I put XP-L2’s in away. Don’t recall it’s numbers and can’t find any record in my notes. Gave it away literally right after building it. Will ask and see what it’s doing. (he has a lightbox)

Edit: He says he got 3800 OTF with the XP-L2’s in the C8F, but he uses older Samsung 20R cells. I seem to recall I got like 4200 with a top cell, I just can’t find my notes on it. (probably scribbled on the side of something else)

Seems like the XP-L2 is a clear winner in the lumen game between those 3 choices. But…

Yes, but from 3 XP L2s, which are known to have even worse tint shift than XPLs.

Is the tint shift from dedoming or just from the massive amount of amps they pull? I plan on leaving them domed and would like max output. I know the XP-L2’s have a very low forward voltage, but I would imagine 3 running off of one 30Q would be reasonable… right?

Also, anyone ever get any beamshot comparisons between different emitters in the C8F? I remember reading someone asking for some but I don’t think they ever got posted.

Thanks! Thumbs Up

There you go:
Sorry for quality.

From table to ceiling:

Outside:

My opinion is that not much gain with the XP-L2 by eye. What you can see with the spill you can also see with the HI led but the XP-L2 draws much more current and heating up faster. My XP-L2 version draws above 16A and puts out 4550 lumens at start.
The XP-L HI version draws 11-12A and puts out 3300 lumens and out throw the XP-L2.

ZozzV6, thank you so much man! I think I was pretty set on the XP-L2… but now you have me questioning it.

The HI looks equally as bright as the XP-L2 with a bit more throw. Which do you like more?

As you see it. First I built the XP-L2 because go big or…. but for a friend later I built the XP-L HI. If I have to do it again I will build an XP-L HI for myself.
Maybe when the 21700 host will be available.

Use XPL-HI or LH351D to get same beam as xpl2 but with better tint.

The Samsung LH351D is a viable option but again for what your get and the better control of run time the HI is probably the right way to do it.

Remember the big multi emitter lights where the multi reflector is screwed in at the middle? This one is like that, but a lot smaller and as such there is very little room to work. It’s doable, but tight. You just have to be careful and take it slow. Probably 20 ga leads is sufficient, 22 ga would be even easier.

Nice light, the side switch really works great in this size and shape. Pretty sure you’re gonna like it. The reflector gives a tighter beam than the CUTE-3 optic, so it’s a win all around in my book….

Ok, I know Vf’s aren’t the same but what would happen if one were to put an Samsung LH351D, Cree XP-L HI and Nichia 219C on the triple MCPCB? Like an 5000K 80 CRI Samsung, 5000K 90 CRI Nichia and a V3 3A HI? Should be doable, yes? Maybe not optimal, but should have a nice color and be interesting, right? Just a thought…

I’m the same way man!

I can hardly tell the difference between the two pictures, so the added heat from the XP-L2’s probably aren’t worth it then. Thanks for the help Zozz and DB! Looking forward to seeing the new 21700 light soon!

I have one of the C8F’s that has been crying out for Anduril, so I am about to rebuild it and go with the 3 different emitters just to see what shakes. Big Smile

I don’t have an Samsung available but I have one in a D1s and I have one leftover XP-L W2 2B I’ve been saving… so the swap will be made to get the High CRI into the Sofirn light and the high lumens emitter into the thrower. We shall see, at the very least it’ll give me something to do for the next hour anyway. lol

qidong yang: Hi, thank you for your support of Sofirn flashlights. the upgrade C8F 21700 version will keep the Cree XPL emitter , and the estimate time of the first bunch produce will be around 20th, July. In order to meet different demand of customers’ DIY, we will sell the new host as well at that time

I don’t know why Sofirn send info to more people on BLF to write in the same thread. Especially I don’t got any info.
