Thanks for the review Unknown00101. I just ordered one. Now for the wait.
Yes, thanks unknown00101 for the fine review and many detailed pictures.
I ordered the Jax after reading your review and am very happy with it.
Especially after a fellow BLF’er kindly consented to modify it for me.
It has been current-boosted and is now using a de-domed XPG2. I didn’t go for the full boost
(to keep the heat in check) but my little Z1 still achieves 190kCd 
Am loving it !
Looks like this JAX Z1 has made a lot of people happy. It is one of the best aspherical flashlights we can find nowadays especially in this price range. 
replacing those R150 R160 resistors with R100 how much you will get with single cell ? anyone done it ?
With a single cell I’m afraid you won’t see a lot of current gain as these buck drivers normally have fairly high resistance. You need to try using two batteries instead to see the increased current to the emitter after the resistor mod.
that i was afraid of, thank you
The stock driver may not be easy to pimp out for single-cell use, but this host works very nicely with a BLF22DD driver.
Also, does anyone know of a cheap plastic cover which would fit this to protect the optics? It’d be nice to carry this in a pocket without scratching the glass or the AR coating. I’m thinking something like a shallow end cap, perhaps even usable as a diffuser, roughly the shape of a petri dish.
Thanks for the review. I got a lot from it, not the least of which being that this is a worthy zoomie (and one I want)!
Remember there are discount codes at banggood for both the complete,light and the host
Thanks. Which is a better buy in terms of quality and throw? This or the UF-1405?
The Jax is built better but has around half the lux when compared to the 1405 if both are running xpg2s at 5A.
I meant stock.
My 1405 had 68klux stock whereas the Jax has 50klux.
I like the jax better, nicer and better quality imo, but the smaller thwart numbers, and specially the price difference (due to MAP policies, just remember that fight BG-GB…) made me go for the 1504 group buy, approx halving the (discounted) price of the jax. Even the 2 cell 1405 complete light is 5$ cheaper than the (also discounted) jax z1 host
If the lumens double, will that double the throw?
What would anyone estimate the throw on this one? 300m? 500M? 700?

Double lumens definitely doesn’t mean double the throw.
Need to know the lux to work out throw distance
Thanks. Duh, don’t know what I was thinking. But double lumens could be what, 1.5x the throw?
Am sure it’s better built, but wonder how it compares in throw and lumens with this one. (2000 Chinese lumens…it DOES use 2 - 18650’s.)

I have the MC-E zoomie from way back when and it leaves the + sign in the die, so don't count on throw. Lumens, well, there won't be a competition to most lights on the market, even assuming it isn't driven to capacity, but that will NOT satisfy the throw-hounds out there.
I emailed hkequipment and they responded quickly.
Said the throw was about 500m on this Jax Z1 2400L.
My 55kcd measurement of the xml2 version converts to 469m. So they’re about the same throw, but the xhp50 should have a larger hotspot with the signature plus sign through it and a heck of a lot more heat.
