Convoy S11 compatible 26350 tube?

My Convoy S11 GT-FC40 finally landed yesterday, and I'm in love. This is my first big emitter (biggest before this was an LH351D) and I'm suitably impressed (although that doesn't take much).

While I've been waiting, I've been searching for a compatible 26350 tube, because I just couldn't shake the desire to have a "shorty" S11. And now that I have the S11 in hand, I think cutting an inch or so off the overall length would actually make this beast pocket carry-able.

I talked to Simon through the official Convoy store on AliExpress, and he confirmed that he does not, nor does he have any plans to, make a 26350 tube for the S11. So I've been working to ID every available light that uses or can use a single 26350, and see what if those might work.

So far I've found:
• Acebeam E10
• Emisar D4SV2
• Astrolux EA01/EA01S / Mateminco MT01/MT04
• Haikelite SC26
• Fitorch P25 / Boruit BC15

I've already ruled out the E10. The tube SHOULD thread on (found another post where the S11 tube threads onto an E10 head) but the E10 endcap isn't removable.

I've also ruled out the EA01/EA01S/MT01/MT04. Found someone on Reddit with an EA01S and an S11 GT-FC40, and they confirmed that the EA01S tube does not thread onto the S11 head or tail. Trapezoidal threads vs square-cut, and different thread pitch.

Questions:

Does anyone have any of the other options, AND an S11, and could test compatibility?

Additionally, am I missing any other single 26350 lights that might have compatible tubes?

An interesting goal… I also got the S11 GT-FC40 4500k and I also love this beam/tint…

I have the ones you mentioned except the Acebeam E10.

Fitorch P25 = the head & 26350 body is one whole piece (non-removable), there is an extension tube to attach the 26350 body tube to make it fit 26650 batteries.

EA01 26350 tube = the body tube does not screw with the S11 (a bit short and different threading)

D4Sv2 26350 tube = the body tube is too big, won’t fit the S11 head

SC26 26350 tube = surprisingly, the opposite (tailcap thread) WILL screw on the S11 head, but I think it’s still lacking in length (doesn’t seem to make contact with the driver), and even then, the other side of the body tube won’t screw/lego with the S11 tailcap…

Thank you for replying and trying all of the options! It's disappointing but I'm glad to get confirmation one way or the other.

I'll look into custom options but I'm guessing that a custom tube would be multiple times the cost of the actual light.
