Tailcaps: the tailcap of my red Convoy S2+ fits and works correctly on the battery tubes for both an Eagle Eye BLF-X6-SE and an Manker A6. (only checked one of each)
The tailcaps for both of those black lights are too tight — they start but won’t screw onto the red Convoy S2+ battery tube.
As noted above — the tolerance for variation is so large on these that a sample of one isn’t proof of any general claim about what fits what.
I’d guess somewhere there are three bins — heads, body tubes, and tailcaps — and whoever assembles the lights just keeps fishing until he finds a complete set and calls it good.
It’s the Goldilocks approach to flashlight construction. Some are too small, some are too large, some are just right.
That’s an oversimplification — threads have to be defined by several different numbers — spacing, depth, slope of the cut, maybe more. We don’t get that kind of precision.
(Or we get the seconds, if there are some that good)
Has anyone checked the threads for the retaining rings? I don’t know if those are done to any standard or not.
Eagle Eyes, X6, SE body fits into Convoy S2 head and the S2 body fits on the X6 head. The S2 tailcap fits on the X6 body but X6 tailcap doesn’t work with S2 body. (similar to what hank posted earlier)
. The old style extension tube for the Convoy C8 (from Fasttech) fits onto the Jacob body however, the tailcap for the jacob is a bit weird (requires a lot of tube to go into the tailcap) so now, the Jacob has a C8 tailcap as well.
Note here what you find does and doesn’t lego together, collect them all ….
Remember as noted above:
even several of the very exact same flashlight may not have interchangeable parts.
Reports are reliable only for the exact parts someone checks, not generally safe to assume true for any particular model.
My guess is Chinese budget flashlights are assembled by people reaching into a big bin’o’parts and trying them until they find a head, body, and tailcap that all are close enough to spec to screw together and not fall apart mostly.
For any given flashlight, some parts fit tight, some are loose, some won’t fit at all, and some are just right.
Out of curiosity, what’s with all the similarities between the Maratac lights and the Lumintop lights? I know Lumintop makes the Promethus Beta QR2 I’ve got, but do they also build Maratac’s lights, too?
Huh, I’ve got a Thrunite Ti as well. Never really even tried to lego them together, although they are very similar lights.
So I’m pretty sure that Thrunite builds their own lights, so it can be safely assumed that those two lights are built by different companies even though they’re very similar. Makes me wonder even more about Maratac. I guess they could have their own production facility and just be making very similar lights to the Lumintop line. I’d love to know something definite on that.
I dont see any reason to swap a Thrunite and a Maratac, since neither offers High CRI. fwiw, the thrunite head will not light on a worm body, but it will light on the Maratac body. The Maratac head will not light on a Thrunite body, nor on a Worm body, Maratac head lights only on a Tool.
you could ask CountyComm
Im just stating my opinion from personal observation, nothing official
Imo yes the Thrunite Company is separate from Lumintop. And No, CountyComm is not a producer of anything, imo they are just a US company reselling Chinese imports (supposedly to the US Military). Same with darksucks.com (Prometheus Beta) they are a US company reselling chinese imports too.
Note also that Thrunite uses MUCH lower low and Medium than Maratac and Tool, plus the Thrunite mode sequence is always LMH, Thrunite is not offered in MLH sequence like the Maratac and Tool. iow, Thrunite driver is very different than Lumintop driver. Also, Thrunite driver is NoPWM, while prior to Oct2015 Maratac, Tool and Beta were all PWM driven.
Look at these LED rings on post Sept 2015 production runs of Maratac, Tool, and Worm… identical… to me they all come from the same Lumintop factory.
Reminder, report what you actually know — there’s enough variation that even several samples of “exactly the same light” may not swap parts easily.
We can’t tell you what you will find out with the parts you get — not with any real assurance it will or won’t work.
