New Sofirn K6 – [NO LONGER ACTIVE]

Hmm, you might be on to something here…

A tube that’d hold 3× 26650 cells, and a head that can hold 3× 26mm TIRs. Perfect match! :smiley:

Bah. Too many emitters on a crowded reflector means that most of the reflectorlets will have so many cutouts on the side as to make them more for flood than throw.

I’d say stick with fewer but intact reflectorlets.

I told them single 26650 and a Ledil cute SS triple optic in a tube light like the SP33

It is quite difficult, sometimes, to perceive what is a direct suggestion or what is an objective “question” (with or without answers), so if you see that something important was said and is missing in post #2, let me know!

So they want to make a soda can light.

I would suggest using a different battery tube than the default SRK battery tube, just to distinguish themselves from the many many cheap crappy clones with the same battery tube design.

7 emitters would fill the head nicely, like a flower pattern (6 in a circle with 1 in the middle)

I guess FET DD drivers sell because of the wow factor on a freshly charged cell, but i would like to see a current regulated driver.
With 1S4P battery config you can supply 7x 3535 LEDs with the necessary current.

Not overdriving them will give better efficiency too and it will stay in regulation until the battery runs low, especially with low Vf LEDs.

High CRI Nichia would be nice i.m.o.

The right TIR optics would eliminate tint shift when you want to use LEDs like XP-G3, and it’s probably cheaper than an aluminum reflector plus glass lens.
They could use a 7 in 1 TIR, like the DQG 3rd 26650.

I guess though, that traditional reflector + lens will sell better, because people expect an aluminum reflector.

With many 3535 LEDs (with appr. 2mm² Light Emitting Surface, like 219C and XP-G3) you can use smaller optics for the same throw, which also means they can be shorter and with 7 LEDs
With a (regulated) FET driver in stead of a buck or boost driver, the driver board can be flat.
So in all, they could make it a short, compact light.

…but maybe they just want to make a good SRK clone…
Maybe they should use 3x or 4x Luxeon V and drive them hard and get close to 6000 or 8000 Lumen.


Yeah i would like to review it if they want me to.

You get those silly petals in the spill too, when you cut away parts of it.

Or more and in tact, like 7, with smaller die LEDs.

For basic consistency it must have the same way to turn OFF in all groups. And fast click is preferable.

Interested to do a review, compare it with Meteor. Can do it on Fonarevka.

+1 on jerommels idea. Change the outer tube design to not look like any cheap SRK clone. Make it a big block knurling or big diamond shape but not the SRK.

Info updated :wink:

Suggestions people have made that I find golden:

- Nichia option, specially the 90+ CRI 5000k that is starting to show up

- TIR optics, specially to get it on the throwier side of SRKs

  • A BLF driver to get it closer to the community (andúril compatible, of course)

PS: there is and extra “n” in my name in the suggestion and review-interest list

Name corrected, sorry :person_facepalming:

no problem

That’s why I suggest eliminating the reflectors and using Carclo optics like the Emisar D4 has, although to fit it’d have to be the 16mm 3 emitter version like in the Convoy S2/S3 triples. Other than parts, all it needs is a spacer, and the machining on that could be kept very simple.

I think Sofirn adding a larger light into their lineup is a good idea.

That said, I think differentiating it from the Q8 is a wise idea.

I love my Q8 lights and use them every chance I get but they’re on the large size. If Sofirn chose a slightly smaller (3x18650) size, it might be just that much more easily carried.

To piggyback on other’s ideas, I like something different in the led department, with a warmer to neutral tint with a nice balance of flood and throw. How that is done is up to them or others with more experience than I have.

Ramping would be great, but I personally wouldn’t need all the bells and whistles that the Q8 has. I leave it in ramping and love it that way.

All said, I’d love something a little different than the Q8, perhaps a little smaller and simplified for an even more affordable cost. Not sure if Sofirn is looking that way, but that’s my $0.02.

I’d also like to be considered for testing out a prototype.

In 6 LEDs there is no practical sense. Blinds close. In the distance it shines badly.
I agree with the proposal to make a normal deep reflector for 3 LEDs. If you want a very large power - put XHP50.2
Need 3-5mm base with a direct heatsink to the case.
Do not do another skyrayking. There are already so many of them on aliexpress.
Make a cartridge for 4 batteries, buck driver for xhp50.2@12v

Look at Niwalker MM20EB

You dont need any spacer. Maybe just solid central rod with thin tube for 21700.
Yes, I dont have decision for negative end springs. So let it be 3x21700.

I would like to see another successful triple design from Sofirn. IMHO, they did a solid job on the C8F. I think a Q8-inspired, C8F hybrid has a good potential, provided the design is nailed right. I think a triple design would make a good sweet spot. Plus, the cost–performance ratio would be desirable, as far as Sofirn is concerned, which means better pricing for the K6. By triple design, I mean three (3) strong LED emitters that can really deliver. As suggested above, XHP 50.2 makes sense considering the cost. The only problem, I think, is containing the heat. Maybe three (3) XHP 50.2 in 6-volt configuration at half of their max forward current?

Also, it would be superb if they could make the K6 host available for sale, in the same spirit and continuing the tradition of their C8 versions.

Suggestions above added! :wink:

BTW, seeing some suggestions, I remind that Sofirn has a 3x18650 / XHP50 flashlight, reviewed here by Lexel .
Maybe this helps on thinking the design/functions of the K6 as well :wink:

Interested I want 3 xhp70.2 emitter and 4×18650

Suggestion added :wink:
