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

Yes m8, unfortunately you got exacly this: there was a XPL version of M2X that wasnt that good but i thought its gone months ago

What is this? Can you explain? :-/

Guys, I had trouble opening my first M2X-UT several months ago. I asked Dale about it but I sold it before I open it. Then I bought two additional M2X-UT again from Stanley. The first one was a total failure from an enthusiast point of view. The report was up there. I asked Stanley about it and he told me he would ask Olight if the unit could be replaced. I got no answer ever since, I assumed that Olight never responded his question. I also send two emails directly to to company itself, no answer…. I don’t blame Stanley for this because it’s Olight’s responsibility to replace defective product via the distributor. If the factory doesn’t do it then it’s a dead end. Then I left the defective one in my stashbox until today. I was so curious about it.

Here’s my findings:

To my surprise the bezel wasn’t glued at all. Came off easily with a twist of my hands.

- I checked the current at the tail cap, with fresh 3400mA 18650 battery the current maxed in 2,11 A

- As I mentioned before the plastic piece is not centering the emitter. Now I found that the emitter also soldered off center.

- The MCPCB is totally different with what Dale posted. Fortunately it is still a direct thermal path one (tested the continuity with my multitester)

  • I SUSPECT that this is not an XP-L HI emitter due to it’s greenish colour and convex silicone lens coating. The dome also asymmetric, thicker at one side. I think Olight was experimenting. They dedomed the emitter then dropped a (too much) silicone coating to make colour shifting less pronounced or to protect the emitter in the long run. I remember my first M2X-UT emitter’s bare die was oxidized (scroll up several threads up for the picture). And they were keep experimenting. My last M2X-UT was the best in every aspect with dedomed XP-L (was it HI or HD, I don’t know) and a very thin protective coating (it’s shiny viewed from the side). And the tint now also cool white without green taste on it.

Perhaps they did it to keep up with the boom of XP-L HI implementations by many manufacturers. They were the first to use custom dedomed XP-L, now everyone can have it with less effort. By keep dedoming, they get the slight edge of the competition. Enjoy the pictures:

I just checked mine, from Amazon.fr.
The PCB is not like yours and I confirm that my XP-L HI is flat, not convex at all

My knowledge in electronics are poor. I think putting two resistors R100 ( parallel) on the top of the two R050, the result will be similar to adding a single R056 . I am right? Will I burn the driver of my M2X if I use a single R100?

I have changed the finish of this light and i would like to get more throw.

Thank you.

I use this Parallel Resistor Calculator to figure out final resistance and help me make an educated choice on sense resistor mods…

Those that are in the know can figure out the actual output through doing the math, but I always forget the formula’s.

Thank you!

I finally used two R100 in parallel.
4,04A at the tail with a 30Q and 190.000 Cd.

Nice neat job of it you did, well done! Fun, isn’t it? Seeing a nice light become a fantastic light…. :smiley:

i have the mx3s and man do i love this light. it throws a perfect beam a ridiculoualy long way. build is very nice. weight amd balance good. its my 2nd most expensive light and worth every penny

First of thank you DB Custom for the super detailed review. The m2x performances really is incredible; let alone the fact it comes factory dedomed! I have the earliest variant with the XM-L2 led; the throw is truly amazing. It never gets old seeing that over half mile beam cutting through the night sky. I’ve even been able to bust some lower level clouds with its beam!

Try a white flat 1mm² in it and you’ll know what THROW really is !

Stock driver or you replaced it?
I presume stock is ok at about 4 - 4.5A

Can I put a flat white in my M3XS-UT?

Yes.

What would the throw be with the Flat White in the M3XS-UT approximately? And the lumens. Can I just unsolder the LED and put a flat white on it?

I used a Osram projector bulb about 15 years ago, with a Maglight reflector and a battery pack out of $1200 Speedglass welding hood. I didn’t know anything about Li-ions at the time, but during the third charge the pack started venting and I ran down stairs with it and threw it in the garage. I think I was draining 4 or 6 18650 cells in about 2-3 minutes during use. It looked like a freaking freight train. I had a D cell maglight reflector zip tied to a ball cap and the battery pack in my backpack. I hit the on button and someone on a back country road came from behind us and once he got in front of my brother in law and I, I looked at the truck. I was not thinking I just blinded this guy. But once I did , he stopped, I kept smoking him. Then I guess he decided several thousand lumens in his face was not worth getting out of the truck. He drove off slowly. The next battery charge was exciting. The one that violently vented.

Throw. Not sure, never done it.
Lumens. Just guessing, about 800-900 !
Yes, you can unsolder XPL and put another led but original olight mcpcb is thicker chunk of copper and needs time to heat up + centering it (led) properly might be a bit challenging.

Okay, here are my numbers:
M2X with bypassed sense resistor and 1mm² White Flat : 4,5A, 359kCd
M3X with stock driver and Black Flat : 5A, 542kCd

The Black Flat can’t be put in the M2X because the head is electrically connected with battery minus pole

Does this light have lvp

Yes.

As in it has lvp cut off
