Aha, the holes in the pill for the wires have sharp edges too…
So basically this light has to be disassembled completely and all parts have to be checked and taken care of, and then you can reassemble the light.
Yeah, sounds like my hobby. 
I think the loose head can be fixed too by using fatter O-rings.
Looking forward to receiving this light.
Except for Emisars or BLF-Lights, that is what most of us do anyway, I guess 
From what I hear, the head on the Jaxman Z1 doesn’t rattle.
Ok, driver in my first one is seriously compromised; now only operates in 3 modes L/L/M - compared to the fully operating one.
Not sure I can be bothered with challenging BG over the issue, but wondered if anybody could point me to a good replacement driver that would work with this setup?
Actual driver boot is ∅22mm like Jaxman Z1, doesn't it? You could go Kaidomain's H2-C boost driver plus XHP35 HI. Sense resistor is 1206 imperial units, 75mV sense, thus add an R100 over the stock R050 for up to 2.25A driving current.

Cheers ^:)
No, I would not bother BG with issues with this one. We knew that this is the Cometa with known issues and we are getting them cheap because of that. See it as a wonderful host and that you have to look over every part to get it right.
As long as they’re not glued shut. :person_facepalming:
Its got the upgraded BLF driver from the X6 driver.
I was going to put an SST4O in mine but the hole is to small for the LED. So i will drill the hole out with a 5mm drill bit see how i go.
I’m amazed at you guyz
doing this all over again
at whatever price
I was never in the Cometa group buy. And this time it is not about receiving a outoftheboxperfect flashlight but about great material for a nice DIY project for little money.
The Jaxman Z1 is using a 22mm driver but i heard that the Cometa is using a 17mm driver.
Can someone confirm the driver size from the currently sold Cometa?
@chinooker
I did not bought in the Groupbuy. But at this price i could not pass! It is still cheap if you take it as a pure host.
Can someone please list all "hot spots" one needs to look upon when disassemling the Cometa, i.e. all potential hazardous areas that might cause shorts? So far, I noted:
- solder joints on LED aluminum board (potential for bad solder jobs)
- sharp edges on the pill that might damage the insulation of wires
- insulation disc on the rear side of the pill is crucial as the outer rim of the pill might cause shorts when in contact with the positive pole of the battery
Anything else?
Received mine this morning, but no free gift (the 2x18650) only the 26650 in a bag. I’ll see how it stacks up against my modded Warsun X50, X65 and UF-1504 later. On first impressions, size wise, its a little more pocket friendly.
My 18650s shipped separate by slower mail so keep an eye out.
My “shipped” package (w/o cells) is still in the “label created” stage, ie, nothing was handed over yet.
The other (w/ cells) is still back-ordered.
Kinda interesting to see how this plays out.
Thank for the links Barkuti, looks like a good option I will order now.
Tested my working one for the first time last night and it’s pretty impressive in terms of throw compared to my D1S and GT Mini, though I realise they are both much smaller and I’m not comparing apples with apples.
Please make sure first the Cometa can fit the driver. My reasoning is only a guess because it is a Jaxman Z1 based flashlight with the driver pocket reduced somehow to ∅17mm for the whatever driver it uses, and this is what caused cell shortcircuits when coupled with big headed 26650 cells, is this sort of right? This means you'll additionally fix this potential issue with a proper ∅22mm driver.
All in all, while more expensive the build should be nice. If you opt to drive the XHP35 hard it will be pulling more than 10A at the tail, hope the torch uses a good switch.
Good luck.
Cheers :-)
Yep 17mm driver you need to make space for the driver to fit. This is what actually caused the shorting issues originally it was meant to be a 20mm driver like the jaxman.
Also you will need to make the hole bigger in the LED retaining disc so it can fit a XHP50 in it. It only just fits the XPLHI as is.
