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 donât get a big boost in output, but maybe you go from 12k to 14k lumen (xpg3) and itâs consistent for a long time until it drops out of regulation. So itâs not a big upgrade, itâs just more reliable and has a better UI.
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 floodâŚ
I completely agree. Itâs 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.
I just got my latest order of LEDâs in the other day, that should give me all the LEDâs 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 pcbâs. 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 âdowntimeâ.
Fortunately, I donât need a driver - yours is already installed
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 tubesâŚ
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.
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 doesnât even get warm all the way to light step down. Definitely a necessary step.
Hmm, not sure if I have one on hand right now but I should have one for myself by the time I take the XHP70.2 GT out for some beamshots, I will try to remember to take it along for comparison, also the mt09R.
