Please help me to understand. What do you mean by a new driver from lexel? What does new drive do and how to do you replace new drive onto MF02? Thank you.
Lexel will have a new buck driver available similar to the one in the GT. You convert the battery carrier to 4S, then install the driver. It runs NarsilM on it. You can use the xhp35 or even an xhp50 or xhp70.
Lexel is also working on a boost driver. You can leave the MF02 battery carriers at 6v and run your xhp35 at 12v. It is predicted to do 3A at 12v and 6A at 6v. It also runs NarsilM. It is not ready, though. Maybe in a month.
These should be higher quality than the factory drivers, plus run a better UI.
Well, it all depends.
There is always fluctuation in performance from led to led and in general CW has more output then NW.
My TN42 CW has an output of 659Kcd, according to Djozz.
TN42 NW will mostly be around the 600Kcd mark, CW MF02 could be around 480Kcd and with a little tinkering could be well above 500Kcd.
I know of a member of the German flashlight Forum TLF that has a MF02 NW that reached 538Kcd with a little tinkering.
Looking at the reflector size I think this is quite respectable.
But, like I said, I just like the MF02’ design.
If I can still get one with the GB Discount I will.
Stock drivers are usually 99.9% non-reflashable unless you have the factory firmware to tinker with. They are definitely not using a attiny mcu like a lot of BLF lights use.
I did that measurement and can confirm it on 10m @2.5A current GT NarsilM driver and XHP25HI E2-3C got over 530k on all measurements
The stock CW MF01 diode in my sample seemed with 464kcd not to be a good D4 bin according to those measurements more like D2
I measured also two 100mmthrowers
Niwalker Vostro BK-FA30S thrower with 685k
a stock CW TN42 with 665k and after mod with GT driver in it @2.54A with 705kcd
so my readings seem pretty much in line with most other reviews of similar lights
