Sofirn C8F host. 21700 C8F Available

Ramp top is not adjustable. 1800 lumen is safe and sustainable output in this light with some warming. Turbo is I think 3000 lumen will be in factory data but they measured 3500 on a prototype. Better than tell more and get less. Visually to the eye it is no t a huge jump from 1800 to 3000.
If they use this firmware in the SP70 I think there will be ramp top at about 4000 lumens and turbo about 6-7000. My XHP70.2 MF02 with Andúril is setted up ramp top at 4000 and turbo at 8-9000 depends on battery level and type.

Here is the complete menu:
4 mode Groups:
Group 1: 500lm
Group 2: 100lm—700lm—1800lm
Group 3: 10lm—100lm—500lm—1800lm
Group 4: Ramping from 1lm—-3500lm
In any mode, including OFF, hold 1 second to go to Moonlight
In any mode, Double-click to go to Turbo 3500lm, one click to go to the previous mod

Group 1/ Group 2/ Group 3:
Short click the side switch to cycle through modes: Eco→ Low → Mid→ High→ Eco→ Low→etc.
Press the side switch for 0.5 seconds to enter Standby (main led is off).
4 Four fast clicks convert from one group to the other, 2 blinks confirm the change.
Group 4: Ramping
Press and hold side switch to ramp up or down. Ramping changes direction when press button again within 1.5 seconds, same direction when ramping again after 1.5 seconds. The light blinks when it reaches Moonlight or Turbo. When the light is on, click to Standby.
No matter in which group:
Hold and press the side switch for 1 second to enter Moonlight from Standby, one click returns to Standby.
Double clicks to activate Turbo mode from On / Standby, one click returns to the last brightness used or Standby.
Triple clicks to activate Strobe mode from On / Standby, one click returns to the last brightness used or Standby.

Memory Function: The last brightness used can be memorized when convert from Group to Group. When it goes back to the group, it starts from the remembered brightness level.

OFF
Press and hold the side switch for 0.5 seconds to enter Standby (except in Ramping Mode).
Click the tail switch to Cut Off. Please click both tail switch and the side switch to turn on if the light was in Standby last time.

Advanced Temperature Regulation (ATR) technology:
If the head temperature reaches 50 ℃ (122 °F), the flashlight will automatically throttle down to lower mode to avoid overheating

I kind of like the ramp to 50% instead to max so I can easily access that mode knowing the lumens can be maintained for a much longer period than turbo. That’s how TA setup the default ramping on the MT09R and MT03 that he modded for us and it was perfect.

Switching perfect I reckon at that.
with a 26650 battery it’d be even better.
But I’m just a 18650/26650battery person. the lesserer the betterer.
Plus the 26650 is perfect fit for my hands.

Maybe…

He’ll share a bottle of my10yr old Taliskers with me tomorrow watching Cowboys game
to pay for it
He split a bottle of Glenlivet Founders reserve with me on Thurs,
watching the Bronco’s win over e thbunny’s.
both of those are 46 proof. Ice mix only.

Missus shouting me half her ltr bottle of Baily’s with ice
for the Melbourne game tonight. With a large packet of Licorice Allsorts to flavour it with.

One of the problems with that is that “50%” varies depending on the battery level.

IdK, I guess I’d have to try it. I think the GT and GT mini ramped to 80% and that was fine. 50%, IDK.

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.

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

Water not ice for me, please. I’ll bring Ardbeg for some tail spring bypass :slight_smile:

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” :stuck_out_tongue:

Lol purist, loyalist, enthusiast, old forgetful man, I meant nothing bad by it! Quite the opposite even

Yeah yeah yeah, I’m a lot of things but I’ll still be a Toys-R-Us kid long after the store is forgotten… lol (even after I’VE forgotten it!)

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.

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 wouldn’t mind waiting 2-4 weeks for the new version :smiley:

It should be available sooner than that. :wink:
