And it really fits my Convoy C8 (new model with Integrated pill) nearly perfect.
Physical appearence:
Threads are a perfect match and run smoothly without lubrication. The thread on the switch side is a little too long, just so much that the o-ring is not touched by the switch unit. So it’s not waterproof but electrical connection is fine. A pair of LG Hg2 flattops rattles a little, two NCR18650Bs protected just barely fit, but the contact is closed.
Optical appearence:
the knurling seems identical to the C8, but the black anodizing is a little shiny. Not as matte as the C8. And of course between extension tube and switch cap the o-ring is visible. I’ll try to add a picture, but that normally doesn’t work (’cause I’m too stupid to add a photo?!?)
On the cellphone picture the difference is more prominent than to the naked eye!
The Jaxman UV also legoes perfectly with the S2+
And that includes Hoop’s new copper pills for the S2+, they fit perfectly in the Jaxman UV light and I’d guess also in the E2 that 1dash1 pictures above in the thread.
Negative report: the Cometa is supposed to be an improved Jax Z1, but the Cometa doesn’t lego with the Z1 — several things are different

Astrolux S41 and bare BLF A6 lego perfectly fine with each other. I can interchange heads, long or short tubes and switches as I want. Both lights work in any combination!
I was recently made aware by a fellow member that there is actually one component of the Jaxman Z1 that will lego with the Cometa. As I received a Jaxman Z1 a couple of days ago, I can now verify the information is 100% true. The component legos perfectly… :+1:
The component would be ………………………………………. the lens cap. :person_facepalming:
The lens swaps too. I’m actually running the Z1 lens on my Cometa, because I have the old XP-G2 de-domed pulling 5.65 amps and it boosted the LUX up a bit. They fit each other better, no moving the lens around to get it on center. Weird!
Cross-reference for discussion elsewhere (Reddit’s flashlight forum)
Reddit summaries are sometimes useful when people haven’t been ‘through the wars’ as things developed and are wondering “what legos with what”
Brief excerpt follows; more at the original page of course https://www.reddit.com/r/flashlight/comments/4jfc9f/eagle_eye_hosts/
Skilhunt DS16 legos with Manker E14 / Astrolight S41. The threads where the head and body tube match and are interchangeable.
Note however that the skilhunt is an e-switch light and lacks a tailcap switch, so the usefulness of legoing with the astrolight except for an advanced modder, is pretty much nil.
On the other hand, if you have the astrolight you can get 18650 support using the Manker 18650 tube. Note however that the Manker’s o-ring won’t be covered.
Ordered done flashlights from DX on 7/11, the shipment was broken up into 3 separate packages and the first of them arrive on Friday 7/22 a new record for them. Jolly good show! In this package were a couple cheap AA lights. A Sipik SK68 and an Ultrafire C3. I was particularly interested in the C3 as I had heard a version of it would Lego with my copper X5 and this I can happily confirm. Also of interest is that those cheap no name cree AA lights from eBay also Lego with the SK 68, the tail caps are interchangeable and the tubes thread together so you can easily make an xhp50 zoomie.
