Convoy S2 (not +) with 18350 tube?

Oh man, you did what I had planned to do :slight_smile:
Thanks for creating the thread!

I also have the same doubt about which S2+ 18350 tubes are the compatible with the Convoys S2 (black or grey) !

Here is some info, but it does not report to all the possibilities: List of 18350 flashlights (currently available) - #54 by d_t_a

If any member having different 18350 tubes and different Convoys S2 can tell anything on this, it would be much appreciated!

Thanks in advance!

I did that mod with a shorty S8 (+ lighted tail :slight_smile: ), and Iā€™m almost sure I used the S2+ 18350 tube for that.

Stooopid me, I couldnā€™t remember who did it, but it was you djozz :wink: Now I remember!!

The thing is that not all 18350 tubes fit the S2. And despite I like the S8, Iā€™d prefer the S2.

In case it doesnā€™t work (the tubes in the S2), Iā€™ve been measuring and Iā€™ll do it with a SMO reflector and a small pill both from S2 in a S2+ host. With a Led4Power driver configured for 5A!

I just verified the S2 head fits the S2+ short tube and the S2+ head fit the S2 long tube ā€” The tail cap of the grey S2 worked on the short tubeā€”I have a Black S2 that the tail cap wonā€™t work on the short tubeā€”for some reason the black S2 has a tail cap like the S6ā€”- If I remember correctly one of the pills wonā€™t work in the other ā€”not sureā€” I had some triple pills machined and I remember the machinist telling me the pill thread pitch was different between the long and short versions

What a great idea on the 18350/deep reflector/OSRAM KW CSLNM1.TG Zelda.

Really looking forward to seeing how it turns out.

Thanks for your input on this :wink:
About the pill, I hope the S2 pill fits well in the S2+, in case the tubes donā€™t match the threadsā€¦

Sounds like a wonderful pocket thrower.

Maybe in a S6ā€¦ but is there a copper pill available?

Thanks for all the answers! I will keep you guys in the loop.

@Ryzbor: I havenā€™t saw a short copper version of the the pill.

Hereā€™s a pic of S2+ with short pill/long reflector ā€”- as you can see the S2+ head is aout 1/8ā€ too short of accepting the battery tube completelyā€”the S2 head is 1/8ā€ longer ā€”ā€” you might be able to shorten the thread length but Iā€™m not sure how that will affect the short tube with a 18350 cell ā€”most of the time itā€™s already on the short side ā€” you might be able to gain some by trimming/sanding the pill ā€” both the pill and the reflector have a recessed space for the LED board

A quick update: Simon told me that at least the threads are not compatible.
(I ordered a grey S2 and a grey S2+ 18350 tube.)

I have a grey S2 and green & blue S2+ lights using 18350 tubes and everything fits on everything.

Chris

I had already asked Simon and that was is answer :frowning: (Sorry, it was posted in another thread )

Please say something about that combination (gray - gray) when you get it!
I have 3 ā€œtypesā€ of tubes from the S2: black, desert tan and blue/grey (from the ā€œminiā€ S2 18350).
When you get the results, in case the gray short tube doesnā€™t fit the S2 host, I can buy other tubes besides the ones I have and say which fit and which donā€™t and let people know about it.

Chris, the gray S2 is matched with a gray 18350 tube?

The S2+ we know they are interchangeable, but it was shown in another thread that the gray 18350 tube didnā€™t fit the gray S2 host, but that the ā€œsilverā€ 18350 tube was fitting that!

Maybe this has to do with different batches of hosts/short tubes and different places where they are bought? (example, my S2+ tan bought in Gearbest has a different anodizing from the one I bought from Simon)

Unfortunately, I already canceled the grey 18350 tube from the order.
(I have a green 18350 tube for testing.)

All parts from a grey S2+ are interchangeable and make proper contact with the green, blue and orange S2+ parts.

The grey S2+ has just a bit smaller bore as the color ones. (18.75mm vs. 18.9mm)

I noted this in Post #5 ā€” I guess a picture is worth 35 more Post about whether they fit or not

I know you did mate, and I was not doubting you, but conflicting information that the gray tube wouldnā€™t fit, I was trying to ascertain if it was an isolated case! Sorry if I sounded otherwise :frowning:
And thanks for the photo :slight_smile:

Iā€™ll be ordering from Simon soon having this info in hands :wink:
Thanks again :beer:

Yesterday I received my S2 gray and a short grey tube! I confirm the gray, black and desert tan shorty tubes fit :wink:
However the anodizing colour is slightly different from the flashlight.
Here are some photos! You can see that the shorty tube is more blueish (like the Convoy S2+ on the right)
[click to see bigger photos]

BTW, Simon wrongly sent me a OP reflector. Still, I moded the light with a Led4power LD-A4 driver (configured to 4A) and an Osram white flat! The beam looks more defined in the photos that in reality, but is still nice! Iā€™m still thinking about buying the SMO reflector or not.

Please put a pointer in the thread called

What Legoes with What?

when you figure something out for sure.

Sure hank, just did!
Posted here: What Legoes with What? :wink:

I received the S2 host and did following:

- Replaced OP with SMO reflector (with only 5mm opening)

- Replaced spring from switch with stronger spring

- Brass contact for driver (no spring)

- led4power LD-A4 driver, set to 4.5A

- OSRAM KW CSLNM1.TG (1mm2)

- 18350 tube from a green S2+

  • Keeppower IMR 18350 750mAh Battery

This small thing puts a stunning amount of light with a intesive small hotspot!
Gets warm/hot pretty quick too :smiling_imp:

Iā€™m reading 23500lx from the S2 with Osram, from a S2+ with SMO and XP-L HI with 4.5A I get only 10700lx.

Edit: Be aware that a protected 18350 maybe not fit with this parts! You need a shorter spring.
