New Sofirn K6 – [NO LONGER ACTIVE]

I’ve got the same request from Sofirn official store, and my answer was that I am not sure that there is a place on the market for same type of light like Q8, with similar or same UI like Narsil.
Personally I like the idea of having more lumens but 6 led reflector usually have much floodier beam then with 4 led, so my vote goes to 3 XHP70.2 something like Utorch UT03 prototype …

Also If K6 went to production,I would love to be on the list for testing.

I think putting it on suggestion is fine…

I have one suggestion for the UI. The non-ramping mode group should have “press&hold” to change modes and “fast click” to turn off. I find this preferable to the other way around, as you are less likely to accidentally register a double click; I also find a short click to turn off to be more intuitive than a long press. It would also be more consistent with the ramping mode - in either group, press&hold would change brightness while a click would turn the light off. With the current setup, the interface changes depending on which group you are in, which is less intuitive.

Contributions added :wink:

Delta_V, just one question: when you mean “press&hold” you mean it like the Emisar D4? Or did you mean “click + press & hold”? Meaning one click for ON, then press & hold to change modes, like the Olight lights?
Sorry, I was just manipulating some of my lights and got that doubt!

Like Olight. Click to turn on, long press to change modes, click to turn off

Thanks for clarifying! Will change the suggestion text :wink:

Hmm, that’s a bit tough. Given that we, the BLF community, recently created the Q8 to meet our desires… creating a similar light and asking for our input might take us dangerously close back to the Q8.

I like three idea of having fewer emitters (say 3) and make them XHP50.2’s. Or better yet, 3x XHP35 HI! That way we have lumens and some throw. I mean, what does a 10,000 lumen pure-flood do for you? Blind you up close it seems to me. Don’t get me wrong, give me those lumens! Just allow me to cast them a bit farther.

And I do really like how Sofirn is accepting of feedback. Very nice. And I’m always up for testing a light :slight_smile:

Hum, I got the point, completely! I don’t have the Q8, and I only one “big light” (Amutorch AM30), but I see all the points about that possible comparison! I guess it will be hard to beat the Q8 :partying_face:

Suggestion added :wink:

The advantage of multiple XP-L emitters is you can get away without using a boost driver like you would most likely have to with XHP emitters. Lets you save on driver cost.

That said, if XP-L emitters are chosen, would be nice to have XP-L HI emitters for at least a bit of throw. The additional lumens of HD emitters would be unnecessary in this application.

XP-L HI emitters added :wink:
Not having information about the driver, I will not post about it being boost or not, but if necessary, that suggestion will be added later as a complement!!

EDIT: Just added one question myself, about the Moonlight mode.

REFLECTOR AND LENS

- Triple XHP50

  • or Quad XPL

EMITTERS AND MCPCB

- I would choose 3 XHP50 over 6 XPLs, because the reflectors with 6 have a relative small reflective area due to the neighbor cutouts

- Option to get 3 CRI90 XHP50

  • MCPCB designed dual footprint with XHP50 thermal pad non conductive (1206 Resistor pad bridge for example)

DRIVER

  • 2S/2P Boost for 3 XHP35/50 12V

USER INTERFACE

- from Off short click last memorized mode or first mode of mode order if disabled

- long click from Off Moonlight, remove c) hold 1 second to get a memorized mode

- 4 clicks from on as well lock out

- Option to Moonlight with down to 0.1 lumens in ramping

- option to enable disable memory

- in modes an option to enable/disable moonlight and change mode order

  • 3 short presses for strobe advance with long click to beacon and battery blink out, normal click to last mode

THERMAL STEPDOWN

- if this is not calibrated and based on MCUs spread this will be not good, some will be too high others too low,
I calibrated a hundred Narsil drivers and the spread is +10°C/-15°C sometimes even 20°C

- get this with a external NTC on the MCPCB and raise temp to 80°C

  • the thermal step-down should use a slow dimming down instead hard step-down’s

OTHER ASPECTS

Put me down for testing and review
I will even prefer a early pre production sample

How about 3*XPL and 3*XPL-HI ?? and 3 orange reflector and 3 smooth reflector? use by turns?

Lexel and Jackie, suggestions added above! Thank you both :wink:

BTW 1: If anyone feels I left something out of the given suggestions, please let me know! I may fail on this :person_facepalming:

BTW 2: the links for the general thread and the posts #2 and #3 where already sent to Cissy! I will send it to Tracy as well, being the Sofirn rep on BLF :wink:

:+1:

Is there any pre-requisites for being in the reviewer interest list? My experience with Sofirn lights is based on older models (but I have 2 newer AA/14500 lights in the mail) and would like to contribute do making a better product, bering in mind that the recent Q8 is kind of it’s kind and a new light would benefit from not aiming at the exact same spot

How about six 4000k Luxeon V emitters with a MT03 type floody beam?

Set high level around 2400 lumens and give it enough thermal capacity so the light can run continuously without stepping down.

A tripod mount would be nice as well.

Hum, pre-requisites, not that I know!
As I mentioned, concerning this light, I will list the names of the interested people for test / review, and then the manufacturer will decide on who to choose and send them! I don’t know the exact criteria - if it exists - , but it may be based on the contribution for this light’s discussion! :+1:

Suggestions added :wink:

Gonna sleep now. Updates will be added in the morning… :arrow_right:

Change this f#cking SRK style extruded tube with simple tube with big bore inside. With parallel connection it will allow to use 3x21700 or 4x18650 with same tube.

I wish for enabling or disabling Memory as an option.
If memory enabled the fast click from off would be the memorized mode.
If Memory disabled the fast click from off would go to the Low (non Moonlight mode)
The above would be within the ramping group.

But it is bad timing to introduce this format of light after the Q8.

Or it could be a good time. There was talk about a Q8 like light with more emitters and also a triple I think. That would be a ways away. If Sofirn can keep it budget like and have consistent quality if could be a hit or a filler befor the next BLF Q8 iteration.
