Olight Javelot M2X-UT Review *Pic Heavy* ---===11/19/14 Updates===--- Dual Power Supply Capability

Looking forward to seeing the end result (& the Superb work that led to it)...

Isnt the m3x the original stl-v2/maxtoch etc?

Man things change so fast in this industry. So awesome

Chris

Ok, yesterday I opened up the M3x Triton and found that the head is deeper because of the difference in driver. The driver does have the wires attached to the big star, those 2 little red wires out on the edge, and the star is aluminum. And the pill is hollow, there’s nothing under the big star! It sits on a fairly wide ledge though. I will be re-doing that, for sure.

I pulled the star out and heat it up to get the XM-L off, put a de-domed XM-L2 U2 on it. There is a row of sense resistors, a long row, like 7 or 8 of em. Most were R100’s but not all, there was a 2R00 among em and a couple of others. I took a stab in the dark and stacked 2 R056. Couldn’t get it to work outside of the body to test it, so I put it back together and tested it on 2 Sanyo UR18650FJ cells from a laptop pull. 2.56A at the tail…. is that double to the emitter? Or near it? With Efest 35A fully charged and rested it showed 2.43A at the tail.

Output is 1135 OTF at start, 1014 at 30 seconds. 196Kcd and 885.44M throw. So I did gain considerable lumens from the stock XM-L at 700, if the tail amperage is indicative of around 5A to the emitter, then it’s doing about what I’d expect except that the throw isn’t where I would have thought.

Still on the stock driver though, so it still has the twist head for mode changes. So, the dilemma on my hands now is which one do I modify with an MT-G2? If I’m going to have to create a large copper sink for the Triton anyway, since it has a hollow pill, then I might as well do that one with the big emitter. I did get the extension tube for the Javelot, but of course I have it set up now to run single cell only. And it’s so truly potent I’d kind of hate changing it, the smallest thrower I have at anywhere near that throw level.

Might just sell this Triton in it’s new and improved state and do something else with the MT-G2…decisions decisions decisions.

Anyone looking for a bumped but otherwise stock Olight M3S Triton?

Sounds exactly like an stl-v2/6 with the hollow pill, but near 200kcd is doing well, mine is only 150kcd.

What are the markings on the driver?

And are you thinking it has a thermocouple input? Could be bypassed?

Chris

And has the two wires connected to the star with some kind of component also on the star just beside the 2 wires. I don’t know about all that stuff.

Will be a type of thermocouple, as the heat changes the resistance increases etc.

Interesting that its built into the star though

Chris

Someone tell me how well the 2Xshooter measures up to the M2X? In brightness and throw, how does it measure up stock?

Stock, the Javelot is the better thrower pretty solidly. That’s considering my Triton was the older XM-L version.

I tried bumping power on the Triton a bit more and , uh, well, lets just say that the newer XM-L2’s don’t like 8A.

I went through some old de-domed XM-L2 emitters and checked forward voltage in direct drive off a Sanyo lap pull. Found one that was sitting at 3.49Vf in full direct drive. Bingo!
So I put that one on the star, dug through my stuff and found the big, thick copper star that came out of a TK61…cut that to fit snugly into the pill under the aluminum star. So it’s got some backup, as it were. I pulled one of the 2 R056 resistors I’d stacked, left the R025 on. At the emitter, with a pair of Sanyo lap pulls in semi charged state, it showed 6.65A on the clamp meter. I grabbed a pair of Efest 35A and topped em off in the charger, tail amperage shows 3.65A from these! .19A in low, which is in line with what low did at the emitter on the Sanyo’s, .39A.

Does this mean I’m seeing about 7A now? Still only makes 1221 lumens and the lux actually has dropped to 186.5Kcd.

So, pushing this Triton for all it’s worth on the stock driver it still doesn’t stack up against the Javelot with a piggybacked BLF FET driver. Crazy, huh?

:stuck_out_tongue: Not very often.

This one is no exception. I discovered that the thick Aluminum star in the Triton is not Direct Thermal Path, hence the big drops in lumens during run tests. So, I improvised. I removed the de-domed older XM-L2, put it on a 20mm Noctigon but with copper pedestals under it to raise it up for better focus ability. Then I bored out the center of the big aluminum star for a press fit of the 20mm Noctigon into it. This keeps the Thermal Management and puts about 3.5mm of copper under the emitter.

I now have 1397.25 lumens at start, 1235.1 at 30 seconds, with 197.75Kcd and 889.38M throw. Whew! What a lot of work for the little gain, but now I know it’s the best it can be. With 7A from the stock driver and the light still functioning as normal, it’s time to leave this one alone. :wink:

I think the little brother, the M2X-UT Javelot, still outdoes it…which is very impressive indeed!

Thats dedication!

What do you think, how far can be default Lavelot driver pushed? Cause LD1 modded Y3 beats it( U3-2a emitter, from IOS) , and with 4200ma Keeppower battery it ever outruns it
Still havent recieved the extender tube though…

Compared to Sniper M24, they are virtualy the same, ofc M24 is heavier…now Amanda sended me the second edition one, but it will come who knows when

I stacked R056 resistors on top of each R100 and got 3.56A. I didn’t want to blow it, so that’s as far as I went before pulling the stock driver and going with the BLF FET version.

Thanks for the Great review Dale. I’m currently looking at the TrustFire X9 in the same form factor, to save some money. Maybe any other recommendations for a good value for money ‘Javelot M2X Clone’?

DB,
I had no luck at all, I could only open the driver’s thread. Unlike your picture, my M2XS seems to have red loctite on it, not blue like yours. Judging by the smells it is definitely a threadlocker. Killed two baby boa. Heated the bezel with hot air gun to a bit more than 100C (water droplets vaporize instantly). I stopped because there’s an o-ring inside (I saw from your picture)
I made two pair of round clamps from wood and clamp the bezel to a vise while turned the smaller head using another smaller vise. Because the smaller head has vertical grooves, it’s very slippery and requires high clamping force. I stopped because I think I already put too much clamping force to the bezel and I don’t want to break the glass, the aluminum bezel is too thin.
I need to know if the thread at the bezel is clockwise or anti clockwise before I continue to try again.
It seems Olight really protective about this one =(
Many thanks,
Clemence

Clockwise, and yes the bezel is very thin on these. They gave it the largest possible reflector/lens diameter which of course has the potential to cause us issues if modifying.

I have put the parts in a baggie and boiled them before, but it sure makes it difficult to handle when trying to disassemble.

Good Luck! :wink:

these are the shunt resistors, right?

this flashlight runs too cool, need to overclock :slight_smile:

There is a new M2x Javelot revision btw, the XLP got a new full cover pad, the tint is already 4500k( not like the first XLP HI versions) and the tail amps are 3.4 by default and 170-176k cds( tested all 5)

Now thats a realy good XPG2 host :bigsmile:

Got 5 of those, all are the same- the head isnt glued too, will try swapping the emitter`s wires plus a spring bypass

When my Dad see’s one like that he’s amazed at the sheer intensity of light coming from that comparatively tiny little yellow dot down in the bottom of the reflector. “All that light is coming from THAT?” :slight_smile:

I just got my second M2X-UT from *. Tested it right off the box. It didn’t throw as far as my first one!!! The hot spot was bigger and elongated to one side. I heard that some people also experienced lower performance from the new M2X-UT using XP-L HI emitter
The tint is better, more like “normal” cool white, not the greenish warm tint.
When I went back to my house and checked what’s wrong with the flashlight I found these:







I guess this is the cause of some new M2X-UT sold. It’s not the emitter but the misalignment of the emitter relative to the reflector. My new M2X-UT plastic center alignment hole piece is circular not square. I suspect I got the batch from the transition period from XM-L2 to XP-L HI. :expressionless: :expressionless:
