I read through the thread and am interested in the light, just need to decide which emitters.

I saw lots of lumen numbers but no throw numbers. Anyone have any?

I gave my good lux meter away in a trade last week so I don’t have a way to get good numbers at the moment. I ordered a new meter yesterday though.

All the LED’s should give similar throw numbers for a given lumen output, dedoming is what will improve throw. In the GT it improves throw by around ~40+%.

There are at least 2 lights coming that want a dedome. Just not sure when they will get here.

I got a few more orders in yesterday. The first one is from Krash610. He sent me 2 xhp35 lights.

One of these was just going to get a driver but he decided to try some E4 bin XHP35 HD LED’s, so I have to wait for those to show up.

The other I just got finished with, he wanted the 80cri 4500k LED’s with the TA driver.

Interestingly this light is doing much better then the last one I built with these LED’s and I have no idea why. I even pulled out my old meter to compare but it said the same thing. It is possible the last light I did the lumen test with low batteries.

This light is doing just under 7000 lumens which is very impressive indeed for an 80cri LED. Once again the tint is fantastic. I so love 4500k.

I also got an MT07 in for modding, I was not aware that it was wired in 4S so it was a lot more work then I figured it would be to mod but just waiting on the LED now to finish it up.

I think the last one was mine measured at 5700 lumens. Can you check it again with full batteries? I would be willing to pay for another set of emitters if it is really that much lower.

Also tracking says my three MT03 is out for delivery today to your address.

I forgot one of yours was xhp35 and still here.

Well I just checked, rechecked and swapped batteries, battery tubes was even about to switch the drivers when I think I might of figured out what is going on.

The tints on them are very close, seen separately it is hard to tell a difference unless looking for it. But when held side by side (I just used 1 set of cells at first to keep things consistent) you can see that SVK’s light is slightly warmer / rosier. At first I wondered if they somehow sent me the wrong LED’s as it clearly says on the label these are C4 80cri 4500k LED’s.

Then I remembered that SVK’s light used a mixed tint 4000k/4500k setup, which perfectly explains the difference in tint I was seeing.

The C2 bin 4000k LED’s must just be much lower output then the 4500k then the 1 bin lower would suggest. Everything else between the lights is exactly the same. With fresh cells the 4500k is doing just under 7000 lumens every time and the 4000k/4500k is doing just under 6000 lumens every time I measure them on both spheres.

Admittedly that is a pretty extreme difference in output but I even hooked them up to my bench power supply and verified that they are being driven to the max, I could not get more then ~100 extra lumens on either light using the power supply vs the cells like normal.

So it is up to you SVK, I can swap in some 4500k emitters, or you can stick with what you have. If you like rosy tints, that is exactly what yours has now, a nice rosy high cri tint. If you would prefer more output I can swap them, just let me know.

I got a package in a little bit ago, that is most likely your MT03’s.

Just wondering… how many lumen out put can MT03 do after modding? I have the XHP 70 version.

It is doing basically the same as the MT09, they use the exactly same internal parts so this makes sense.

I should be modding these 3 tomorrow.

If it’s getting 22k with the mods you mentioned then I’m sending it in to you lol!

Yep, The last MT03 I modded did around there, if you dig back through the thread it should be posted at some point. They have all been between 21k-23k at this point I am pretty sure.

hoping we can find out the lumen gain on an MT03 after adding the TA driver only. I thought I had read somewhere to was like 3000 lumens on the MT09R? Anybody recall?

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.

SKV89 wrote:

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.

Yes. Mt07s is my light..

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 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?

HaikeLite MT03 II Devourer XHP70 2SPS 8760LM CW/NW High Power LED Flashlight
HaikeLite MT03 II Devourer XHP70.2 2SPS New Driver 12000LM High Power LED Flashlight – White Neutral white light

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.

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.

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!

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.
