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

What voltage is going to the leds?

I measured 9.57V on Turbo

Has it been tested?

And if so what is the outcome?

Okay, I had to refresh my memory and work this out.

The MF01 v1 had 3 groups of 2S3P = 6v with 3 built in drivers, one for each group of 6 leds. Used 6 wires to mcpcb.

The v2 was 6S3P where all 18 emitters were wired together and needed 18v. Used 2 wires to mcpcb.

So what you did was convert the 6S3P to 3S6P which needs 9 volts and uses 2 wires to mcpcb? Correct?

This method requires less changes on the mcpcb?

You don’t get a big boost in output, but maybe you go from 12k to 14k lumen (xpg3) and it’s consistent for a long time until it drops out of regulation. So it’s not a big upgrade, it’s just more reliable and has a better UI.

All this number crunching makes my head hurt. Lol

correct 3 cuts are made on the MCPCB 6S to 3S

The driver regulates output over the whole battery capacity pretty constant
I found recently a better p-channel MOSFET, which has less conducting and less switching losses, so I could increase the current a bit
But that FET has another footprint so new board would need to be made

Absolutely. Mf01 is worth modding… swap all 18 led to xpl hi, upgrade the battery carriers, and new driver… you get 16,0000 to 180000 lumen… those are focus lumen and all the lumen are in one hot spot unlike flood…

Who’s doing mods for the MF01? I’m not talented enough to pull that off.

TA could do it. Lexel ( Germany) can do as well.

Uhh, modding the MF01 with XPL Hi would be interesting, but not really useful.

You’d lose the best aspect of the MF01: the 219C LEDs are absolutely marvelous in terms of color rendition.

I completely agree. It’s the 219C 90+ Nichia CRI that makes this light worth modding or even owning. I really like the CRI on this because the colors do show up better than even the 80 or 90 CRI Crees. Tintwise, I prefer the XHP70.2 4000k 80CRI because it has less green.

Actually come to think about it, if you can put in XPL2 80CRI high bin emitters (not sure if it fits), I wonder if you can get it to pump out 22k+ lumens, in which case, that would be very interesting indeed in a very focused beam with good tint.

Hey, Texas Ace, looks like my light arrived at your place! FedEx tracking said delivered around 1pm.
Hope the mod goes well!
Did I hear you were out of the 5700k p2 70.2 emitters?

From the factory they have polarity protection, you would have to remove that to use flat top cells. Although I highly recommend not doing that, bad things would happen if you put a cell in backwards.

The easiest option is to solder blob the cells. Thats what I do.

Thanks for the info, yes I would need to examine the light before I could quote a price.

Yep, I can mod that just like an MT09. Makes for a very nice light indeed.

The prices and options are the same as the MT09.

Yep, I think that is the box sitting next to me.

I just got my latest order of LED’s in the other day, that should give me all the LED’s I need to finish off all the current orders as of early this week.

I am out of drivers though, the last one I have is being sent to HL for testing next week. I have the components to make more drivers and just waiting for more pcb’s. They should be in Wednesday. About the same time the lights from Terry show up (which is why I told him to wait). I will start up work on these mods again late next week. It will take me a day or 2 to build the drivers.

I needed a few days off anyways, got a lot of other things to take care of in real life during this “downtime”.

Fortunately, I don’t need a driver - yours is already installed :slight_smile:
Just the LED swap, as I installed your driver and did the spring bypass a week ago when your driver came in.
But I understand the need for rest though.
I wonder what the lumens are with everything but the new emitters? I may have to buy one of your lumen tubes…
Have a blessed day!

Ah, I forgot which one that was that was coming with the driver already. In that case I can most likely knock yours out this weekend. Maybe tonight actually since the spring bypass is done, I am so sick of bypassing those springs lol.

Oh and I forgot the lights I was supposed to drop off today at home when I left this morning, so they will go out tomorrow instead. Sorry about that.

WHOO HOO :slight_smile:

No kidding on the tedious spring bypass!
I did all five, sloppily, but with your new driver the main spring initially got hot almost immediately. After bypassing with 18 gauge wire, it doesn’t even get warm all the way to light step down. Definitely a necessary step.

Yep, the driver spring will melt for sure and the rest of the springs are pushed well past ideal without the bypasses.

I can instantly tell which lights were used and which were shelf queens when they come to me by how collapsed the driver spring is.
