Jax Z1 XP-G2 S2 dedomed @5A

Hy,

after reviewing this little flashlight i decided to do some modding with the Jax Z1. The stock Z1 was measured at 43 Kcd so i was sure that there is some room for improvement.

I used the LCK 5A Driver which is powerful and should fit the pills diameter. Bad luck, the driver fits in diameter but not depth.

So i measured the length of different batteries to check, how much space i can loose and the batteries still fit. After i checked that i was sure, that the space left should be ok for unprotected cells. To save space i didn´t use a spring. So i potted the driver with Fujik thermal adhesive on the inner side and took epoxy for the outer side to the batteries. This was pressed together with a clamp to the size i needed.

LED change to XP-G2 S2. Nothing special.

As the LED was not centered perfectly i did that again using the original centerring combined with an XP-G2-XM-L adapter. Now it sits perfect in place.

I removed this centerring after the LED was changed as it produced some ugly rings in the spot. After that the ring was gone but another ugly “shadow” showed up. Only visible up to 1,5 metres but i want to remove that later.

After the mod only unprotected cells fit. I use 2x AW 18350 for a runtime of about 10 minutes Big Smile The body gets warm now really fast.

I measured Lux from 6 metres at 6350 Lux. That´s calculated to 1m 228.600 Lux@1m/Cd or 946 metres range (ANSI).

Distance to target 254 metres, Nikon P100 f=3,2, 2 Sec., ISO400.

That´s a beam i can work with 8) The color is neutral nothing greenish. Now i like this little flashlight even more.

Wow. What a difference. Looks like your trying to sear a hole through the building. Thats interesting to hear about the tint after dedoming.

Nice! Smile

I would not mind knowing the led-current, but that is different from tail-current with a buckdriver, so not easy to measure Sad

Hy,

my multimeter is crap. Volts are ok to measure but Amps are not accurate. But i think 5 Amps to the emitter are realistic.
Theory: 43 KLux (Original) x 1,6 (XP-G2) × 1,9 (dedome) x 1,6 (5A) = 209 KLux.

Greetings

Nice mod and good results! Good to know how it does with a hot setup. I'd prefer a FET based driver for single cell use though, but your setup would be great for a pair of good 26650 cells w/extension tube.

Sweet mod! I’m jealous now!

I already have a second one for our man in Amsterdam (not djozz). But this time i am going to take the most powerful one. When modding the Thrunite Catapult he got the better one.

Does the head twist or slide?

Great work, I always like seeing the red threw aspheric’s.

I absolutely love the look of that light in shorty mode.  Next time use the FET driver in it. Cool

Hi Kenjii, I did a similar mod on the Uniquefire UF-1406 (here) and I am curious about how they compare. Are you able to measure the output (in lumens) of the modded Jax at zoom-in and zoom-out?

Hy,

no unfortuantly i can´t measure lumens. Never did ceiling bounce, too. I am only interested in Lux/candles Smile

Yes, i saw the Z1vn but i don´t think they will be comparable to mine as Vinh uses a single cell driver, so it will be almost impossible to reach stable high currents. MT-G2 and SBT-70 are nice but i think they might produce too much heat for this host.

Hy,

the second Z1 for our man in Amsterdam is finished. Both lights perform almost identically. Measured 225-228 KLux/Kcd.

Hi, er, when taking the Z1 apart, did you have any trouble getting the pill out?

I’m trying to unscrew the pill, or unscrew the black retaining plate at least, and it gets really stuck after about one turn. I managed to bend my tools trying to get it to turn farther.

At a guess, it looks like the black plate might be glued onto the pill or star, and might perhaps have different threading than the pill. So, they turn in sync. It turns easily at first, but rapidly gets difficult and stuck.

So, I’m looking for advice on getting past that, to get the pill out.

Hy,

i had no problems taking out both parts. There was no connection between pill and black plate. I could unscrew the black plate by pressing it with two fingers. Threads are surely different but as i said there shouldn´t be a connection between pill and plate. Perhaps the centerring ring on the LED is stuck at the plate?

Regards

It’s too bad I ordered this just a few days before the host version was released.

It seems like the pill, star, and black plate are pretty solidly glued together. I’m hoping I can let it sit in the maximum-unscrewed state for a while to stretch the glue, unscrew it a little more, stretch, unscrew a little more, etc… and eventually get the pill out. With any luck, doing this will actually stretch the glue instead of compressing it…

I had heard that the MCPCB was glued on with something pretty strong, but I wasn’t expecting the black plate to be stuck too. Glue is a lot easier to deal with after the pill is out.

Hy,

my Z1 is now running with the LED4Power LD-1 5A Driver and an Efest Purple 26650. Short, strong, good runtime Wink Measured at 212 KLux@1m/Kcd.

I got an empty host and put it together with a de-domed XP-G2 and BLF22DD driver. However, the optic is slightly deformed (right in the center) so it gets lower throw than it should. With the battery at 4.10V, it clocked in at only 173 kcd. I assume it would be higher with a totally full cell, but it’s still lower than expected, and I can see a weird asymmetric blob to one side of the beam while focusing it.

So, I may see about getting another optic. It’s still pretty good as-is, just not as much as I expected.

Oooh that looks like a very tasty Zoomie/Aspheric thrower. Tempted to pick up the host and do some tinkering, I like the look of the coated lens as well.
Interesting stuff! Thanks for posting.
