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

Yes, his daughter is doing fine and is back home last I heard a few days ago.

Ok, I got another light finished tonight. This one for Newlumen. He sent me an MT07S that came setup for 4S from the factory. First I had to convert it to 2S which was much harder then I first thought but the results were worth it.

In stock form it was doing 4700 lumens.

Now with a 2S conversion, Spring bypasses, TA driver and 5700k P2 LED it is doing a bit under 10k lumens! (It peaks over 10k for a few seconds)

It legitimately doubled the lumen output. I am quite impressed. This is the most powerful single LED flashlight I have seen to date. I knew that the XHP70.2 P! was capable of this from a cold start from my testing but never actually seen it pushed this hard in a light before.

Holy cow! How does this throw compared to the MT09R XHP35?

Yeah, I was quite surprised as well.

A very quick and dirty throw test has the MT03 pulling ahead in throw by about 24% vs the MT07S.

This is to be expected, even with multi led setups the larger total reflector size is still going to generally throw further. Plus the XHP35 is a much better thrower.

Now with a dedome the MT07S should be on par or possibly even slightly ahead.

Damn nice. Thanks TA.

Yep, I got yours in today! I will try to get it done tomorrow.

Ok, starting work on Keepitsharp’s V1 MT03. I have to agree the V1 is a step up in quality, the ano appears to be HAIII and it just feels a step up.

Before measurements with the stock xhp70 (not70.2) was 11k lumens.

I also realized this is my last 70.2 driver for the moment. I already have the components for 30 more here and the PCB’s are supposed to arrive early next week. So it should work out well with the next batch from Terry that should be arriving about the same time.

Thank you! Looking forward to the* after *numbers! This light was an early pre-order and some of the first had a few flaws. They did try hard to put a good product out.

Yes, as soon as I opened it up I noticed said flaws. Not major but existent none the less.

The biggest of which is the too short battery tube, obviously you have to be careful to get good contact with the cells but not crush them.

Ok, I just finished it up, and final numbers with 4000k 80cri LED’s, TA driver and bypasses are just under ~21k lumens, much improved from the factory setup for sure!

I think the slightly lower numbers are from the very subpar solder used on the mcpcb connection, I tried to clean it up but it has a lot of flux mixed in and I would of had to completely strip the mcpcb and clean it and then redo it from scratch to make any real improvements.

I did not figure it was worth that much hassle for a few hundred lumens but if you want me to I can do it.

This sounds just fine and with your new driver it will be a massive improvement!

Thanks so much!

Is this with the stock LEDs?

This is with 4000k 80cri, I forgot to put that in there.

I have the XHP 70 MT03. So this thing can get up to 20k lumen with mod?
Would 5700k be brighter?

You would need to change the emitters to 70.2 in addition to other things to get 20k+ lumen. The older xhp70 can’t do that much output.

Yes, after a complete mod with all the trimmings it should be over 20k lumens without much trouble.

5700k does not seem to be doing noticeably better then the 4000k. Both are between 20-23k lumens.

That is impressive for the mt03 ( pop can light). 9500 lumen to about 21000 lumen…

I would like to see some beanshots when he got it,

Thanks… i knew already this mt07s was under driven from the factory. I have single xhp70.2 light but max output is 6700 lumen… this is a game changer… i cant wait to try it out…

Indeed it was quite impressive.

Although you can also really see the efficiency drop off pushing it to that level. The 50% top of the ramp mod was doing almost 7500 lumens and going to 100% turbo only bumped it up to 10k but it sure got hot faster!

Needless to say I would only use turbo for short bursts as it is just a lot of extra stress for not much gain.

Absolute madness.

Now, with better cells, like 20700/21700 cells and lower resistance contacts, do you think it would be possible to hit the max lumen output, being about 27 000-28 000 lumens?

Just asking :slight_smile:
