Is Sofirn planning to produce the C8F in a color other than black?

Now I’m confused. I thought you said it only ramps up to 1800 lm earlier?

Being spoiled to TK’s immaculate set-up, I have found the Sofirn ramping painful to use. Slow, enough different that it bothers my “purist sensibilities” Silly

I’ve been eyeing C8F for some time, so any update is welcome even if it’s not using latest UI.

You can get the 18650 version with the old UI or wait for the new 21700 version which should have the new UI.

Does anyone know if Sofirn also plans to update their other C8 flashlights (C8S, C8T, ...) for the 21700 battery size?

I’ve not heard anything about that, or different colors. Sorry. Maybe Sofirn will answer.

They may be using this model as a test to see if people will really buy a 21700 light. It’s still a pretty new battery size.

On the SP70 at least, they said the new ramping will be 3 seconds from end to end. We will have to wait and see.

Sorry for not replying. I got my Imalent DT35 after 2 months waiting and it is DOA so I was upset and made videos and pictures.
I only copied the whole writing and modes what Sofirn sent to me so sorry if some errors they have. The last info about turbo is 3500 lumens. We will see what is the final when they list it on Aliexpress.

Are you saying the group 1-4, non ramping, is still one click on and press and hold for off?

I worked with Sofirn for a long time to avoid that on the SP70 user interface. I’m kind of surprised to see they didn’t carry it over to the new C8F. I really thought they would.

Oh no! The hold for off is the only thing I didn’t like on the C8F. I hope they change it to click for on/off.

I spotted the new light for sale on the Aliexpress store.

21700 C8F link

The battery is rated at 4000mah. Maybe it’s a Liitokala or Lishen under the wrapper? Those two are basically the same battery and a good choice. Has anyone heard details?

It’s a bit more expensive than I imagined at $41 $35 with no battery and $48 $41 with battery and charger.

I believe they will be doing a Group Buy soon.

Yeah, that’s Emisar D4S territory.

Not really. D4S is $48 base model with the 219C or XP-G2 emitters and $66 with the XP-L Hi emitters. The C8F should be able to maintain output better than the D4S although the maximum brightness is lower. I see a $10 coupon at the aliexpress store so you can probably get it cheaper.

It’s their usual 5350K-5700K neutral white. Same as the 18650 version.

That’s for new users on orders over $119. So it doesn’t apply to me.

They probably adjusted the price in anticipation of the upcoming AliExpress sale event. It shouldn’t be near the price of the Emisar D4S, in my opinion. For a few bucks more, most people here would go for the D4S. If Sofirn is smart, they should keep the price near the original C8F. I hope the host will become available soon.

With all the great features ofvthe D4S, it has TIR optics while I like a good reflector beam much better. So I think this light is in a different class.

I hope that they did the ramping well, at least with the Q8 they should have had a good example.

“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.”   (Gus Speth)

I don’t know why anybody would compare the C8F to the D4S. The C8F is slimmer, lighter, cheaper and has a reflector style beam pattern with a distinct hot spot and good spill lighting. The D4S does not interest me at all. ¯\_(ツ)_/¯

Just like you, djozz, I am more partial to aluminum reflector than TIR optics. I know exactly what the C8F is and what it is not. My point is the $41 – $50 range is pretty crowded nowadays. Many good lights can be purchased (after an appropriate discount) at that price range. The thing is, most people here have already built or owned the original C8F. I for one, is not very keen on getting another C8F. Sure, I’ll buy the host, because I like assembling my own lights and I enjoyed building the last C8F.

Whoop whoop! “List price” for the 18650 version all over the place, depending on which specific listing you look at. I expect the semi-permenant “discount price” will look better.

I’m looking forward to being able to order a bare host.

This non-political signature is not non-political.

C8F body is slimmer, but its head diameter is actually larger than D4S.
C8F’s weight is listed as 200g. D4S shipping weight is listed as 187g on Int’l Outdoors – I don’t know if that’s accurate. If so, actual light should weigh even less.
Both C8F and D4S are kind of in between a thrower and a flooder, but yeah, the D4S is going to be a bit more throwy overall.

Current pricing is such that both lights are not far off from each other. Now, if C8F goes on sale for closer to $30, then that’s going to make it significantly more attractive.

I currently don’t own either 21700 nor 26650 cells, so either light would require me to invest in new cell format. Not sure that I care either way.

I already have a C8F and aren’t in any hurry to buy the 21700 version. Looking at the power curves between 18650’s and 21700, quite a few of the curves are very similar, obviously with more capacity.

https://lygte-info.dk/review/batteries2012/Common18650comparator.php

Once you get to the 15 amp range, the 21700’s do start to shine. I wonder what a FET would pull with 3 XP-L’s in it. The light looks the same, just a fatter tube for the larger cell, tail switch, and an illuminated side switch. Is that about it?

I think this stopped being a host thread a long time ago. Maybe it will turn into a 21700 version host thread soon. Big Smile
