Texas_Ace MT09R Modding thread, 20k+ lumens, 80CRI, can start fires? Yes please.

With just the driver the CW LED’s are doing 15-16k and the NW around 16-18k IIRC. Both up around 3-4k lumens from stock.

The results were posted either in this thread or the GB thread.

I think the NW should be doing more than that. My 4000k stock without DC-Fix was getting just 13k lumens which is consistent with your measurements for my light but my stock 5000k measures 32.3% more, which equates to 17+k lumens. Both my friend and I can tell that the 5000k is noticeably brighter than the 4000k. Shouldn’t your driver bump the stock NW emitters to over 20k lumens? Or did I just get lucky and got cream of the crop emitters for the NW.

The NW have been inconsistent for me thus far. Some of them have been pushing 18-19k lumens and some of then only ~16k. Seeing as I have no idea what the LED’s are or if they are even the same LED’s I just picked a number in the middle.

The more I see of these lights, the more I am convinced there were at least 2 separate batches made. I have seen at least 3 driver revisions in these lights and there are 2 very slightly different machining batches. You can not swap the battery tubes between them apparently as it will not quite make contact (the earlier test with your XHP35 lights was like that, 1 tube worked on both, the other would only work on the light it came from).

So with this in mind it also makes sense that the LED’s could be different as well, which would explain the different numbers I have been getting from light to light with stock LED’s.

That is the only explanation I have been able to come up with anyways. It is a lot of extra work to swap the driver with the stock LED’s and then remove it again so I only did that a few times.

This is the light where early versions used 2S2P and later versions used 4S. I think there was a time you could choose which version you wanted. My memory is fuzzy on it. Maybe Terry can give the whole story.

EDIT: See post #263 below.

Both MT03 and MT07 are Haikelite’s first two lights offered for the groupbuy (organised by Haikelite). Both were available in 2S2P and 4S. Most of the driver issues occurred with the 4S variant, so Haikelite continued with just the 2S2P variant.
The more recent offering, the MT07S went back to 4S. Without announcement, the original MT07 went back to 4S as well. It was just a few days ago I was talking to a member who measured the voltage of his new MT07 and confirmed it was indeed 4S to my surprise. On Haikelite’s site it also says 4S, but I have no idea when the switch was made.

Yes. Mt07s is my light… :slight_smile:

It is indeed, I went ahead and finished the 4s to 2s conversion and am now just waiting for the LED to finish it up.

Just want to say haikelite mt09rTA xhp70.2 and xhp35 are some of my favorite lights…

hIKARInoob is right about the first GB done by Haike, and the 4S driver killer and those lights even came with what I thought was a green shoe lace, turned out it was supposed to be the braided lanyard ha ha. what was really amazing was how calm 90% of the BLF members were, it was a massive disaster GB that’s for sure.

Just to clarify on these two posts. There is two versions of MT03 out there, older version that uses lower output XHP70 LEDs marketed with output of just under 9000 lumens, and the newer one being sold on Banggood website with XHP70.2 LEDs listed with output of 12k lumens.

I thought only the XHP70.2 LEDs can have a chance of getting up to 20k lumen output?

Hey how are you doing today Mr T18? You’ve got a couple MT09R lights being super charged by TA right? I’m pretty sure you’re going to love them. Fit and finish are top notch and the beam profile is amazing!

The stock LED’s are either are not that impressive but all the MT03’s I have worked on and are coming to me are habing XHP70.2 LED’s installed so it should not matter what version it came with from the factory since all the important parts are being swapped out anyways.

The only thing that would change is if it had a 4S carrier setup like the MT07 I am working on, it can still be done but there would be extra labor involved.

So with one of the LED’s I am offering in the OP it should be over 20k lumens.

I agree, I really like the MT03 build quality, it is a slight step up from the MT09 IMHO like the double o-rings for example. I also like the big fins.

I have 3 of them here to work on today for SVK89, gonna start on those this morning.

Hi TA,
Can I ask if that is the original MT07 Buffalo (not the smaller MT07s) that you are working on? If so could you provide some before and after measurement or observational comparison comments if not too late. I have one of these original MT07 as well and agree that the earlier MT07 and MT03 seems to be built a notch more robust than the MT09R but performance is far below. I’m interested in modding it but would be interested in how much better the results are. Mine is also the 4S variant so very interested in your comments with this build. Are you using your MT09R driver in the MT07?

Thank you

It is the newer MT07S in this case although even with the XHP70.2 LED it sis was only doing ~4700 lumens in stock form.

I will be using the MT09R driver in the MT07S as well and based on results with the Convoy L6 I expect around 8500+ lumens. Possibly 9k+

I just went live with an interest list for my Lumen tubes / Spheres as well in this thread:

Spread the word, I don’t think I will be doing another batch of them as I don’t think there will be enough demand.

I am also not sure if I will be able to get more of these exact diffusing sheets which just happens to work almost perfectly when stacked in just the right way.

Ok, starting on SVK89’s MT03’s. A stock measurement with the NW emitters had it making 13k lumens.

I just finished the first silver one with 4000k 80cri emitters and it is now doing 21k lumens.

I really like the MT03’s, they are built well and while they are floody they are a good kind of floody. That said the MT09R has a more general use beam.

I might toss a TA driver on the next MT03 with the stock emitters to see what they do.

That’s a nice collection. Those are also the lights I’m most interested in.

It seems the MT03 makes just a tad bit lower lumens than the MT09R. Your MT03 measurements have been 21k so far while the MT09R are mostly 22-23k.

Yeah, I noticed that as well, some of that can be explained but the less then perfect seal I get on the mt03 vs the mt09. Although the last few lights seem a tab lower in general.

These are all off the last shipment of LED’s, it is possible these came from a different reel and are just getting slightly lower numbers. The first lights used the leftover LED’s I had ordered a few months ago.

When pushing lights to the limit like this with FET drivers I have found even very minor differences in forward voltage and die bin are amplified and it is rare to get 2 lights with exactly the same output even if the mods are the same. Even how the retaining ring is tightened can make a difference.

I am working on the next light now, we will see what it does…

Also, I was thinking and I think the only light to hit 23k was one with P2 bin emitters, I don’t remember an 80cri 4000k hitting 23k but I could be wrong, too many of them to remember at this point lol.
