I wish someone would sell a shorty tube for DQG Tiny 4th - this would make for a really small 18350 light since the 18650 version is only 87mm long. The 18350 version would be 57mm long.
I share your sentimentā¦
Pro variant (which supports 18650 extension) is 86, regular is 82.
The pro variant also has a magnetic tailcap, which is why it needs the extra 4mm. the regular DX3B mini has no magnet.

(I wonder if itās the 18350 tube for the Convoy S2, since Iāve tried to ālegoā the S2 18350 tube on an EE X2R and it fits)
Convoy S2 seems to lego with the Convoy S2+ 18350 tube too
The tube is different from the S2, at least in anodizing. The top threads of the S2 shorty tube are not anodized (the edge is). On this tube the threads are all anodized! But, it if fits, maybe it works 
Can you or anyone confirm the compatibility of the S2 with the S2+ 18350 tube? I donāt own any S2 but would like to try it on a short version :nerd_face:

Iām just curious to know. Have you tried both S2+ short tubes (silver and grey) with your Astrolux S41/S42, A6 maybe? Iām very familiar with the Convoy shorties, but I donāt have prebuilt Astrolux lights. I just want to know if I can try and use the Astrolux short tubes with some hosts that I have.
The threading of the Astrolux S1 short tube doesnāt fit the Convoy S2+ short tube and vice versa ā I think their threading are different, which causes both to not completely screw inside each others tubesā¦
Okay, but have you tried both silver and grey? As you can probably tell, the silver and grey Convoys do not have the same fit. For some reason, they are built differently. The silver short tube (and the desert tan color as well) are for later generations of S2+, but they seem to go well with the older S2 tube.
Here is an image: Astrolux tube on the left, Convoy on the right!
The threads donāt match and donāt fit. Well, at least not in my Convoy S2+ flashlights!
EDIT: thanks d_t_a for confirming those matches on the tubes :+1:
Would you care to compare the silver or desert tan (sand) with the Astrolux? Iām more interested in the front thread or the front end for the head. The whole tailcap assembly can be bought anyway, at least for the S41/S42.
I donāt have any Astrolux flashlight, only the tube (I bought it ācause I thought it would fit an headlamp I have, to make it shortyā¦It didnāt fit :person_facepalming: )!
Canāt help with that mate :zipper_mouth_face:
I have Astro S1 on the way. I can compare to my S2+ DT, when I get it, if you let me know what exactly you want me to compare.
Thanks, Pete. Iād appreciate it if you could try the desert tan with the Astro S1. Iām looking for a short tube that I can use with an old host that I like. See the black one in the picture below.
I know for a fact that the S2+ silver and desert tan shorties can be used, especially the silver which seems like a perfect fit, but I am looking for a black one. Iām sure the black and the titanium grey for the S2+ are totally different and will not fit. The same goes with the blue, the green and the red for the S2+. Based on what I know so far, only the silver and desert tan will fit, so Iām looking for something that comes in black and is thread compatible with the silver and dt shorties.
FYI, I purchased a black S2+ short tube from MTN last year, and thatās what I use with my S2+ DT.
This shorty tube works with my blue S2+ as well.
It appears like these short tubes came from different sources in China, or outsourced from different manufacturers.
I tested the Convoy S2+ silver 18350 tube on the black Astrolux S1 ā the tube wonāt screw in.
Thanks. I guess that would rule out the Astrolux for me.
I just bought a BLF A6 silver with the additional 18350 tube from BG. The short tube didnāt fit properly, leaving o-ring exposed. Asked BG to send another and they declined, saying that they have no control over the quality of these parts. Refund instead. Frowny face.
