[Sale] Buck drivers 20, 21, 22, 24, 30mm L6, MF01, MF02/04(S), TN40S/42, BLF GT, Acebeam X45/65

interested in one for GT+XHP70, if possible.

Thanks Lexel

@Lexel Do you have a working buck driver/sell the buck driver with NarsilM for a Haikelite MT09R?

Is it the xhp35 or xhp70.2?

The XHP70.2 version.

Lexel will need to convert it to 12v. I think it can be done since the battery tubes use replacable pcb’s. Iirc, the mt09r has the same size driver as some of his other lights using the buck driver. I’m pretty sure he can do it. We’ll have to wait till he responds for more details.

Have you asked Texas_Ace? He is working on a bunch of mt09r’s right now and is closer in Texas. I don’t know if he has a buck driver made up, but he might. It’s worth asking.

Already did pay for the driver and installation from Texas Ace.

The driver is a 16x7135+FET 2S driver if I remember well.

I just wanted to know if Lexel had a compatible buck driver, since FETs are fairly inefficient compared to buck driver.

I have right now a very powerful Buck in development, but it wont be so cheap parts only are around 40€
With it 6V and 30A are no problem

Since TA seems to keep his new MT09R driver secret to make frofit out of it
I have a similar DD driver 2 FET designed but developing to final product takes time and work and wont be better than TA variant or cheaper
Just it would be nice he shares it so Europe customers can let their lights be modded here with less expensive shipping and I usually mod a lot cheaper

Pffff! 40€ for a 50A buck driver is a excellent deal actually. No buck converter can do this on the market, even ones for high power applications, especially at only 6V.

What I would really want is a dual channel buck+FET driver pushing 7000-9000 lumens on max buck, then switch to FET above that.

Would be amazing, but I doubt that is even feasible, especially within the constraints of a flashlight driver.

Edit: Meant 30A sorry.

40€ are just the parts for 30A
development and labor add up at least another 40€
on CFT-90 LED 3.7V 40A possible

400W is possible going to 5S battery carrier would add enough voltage overhead for 30A @13.5V XHP-70.s maybe the MF03 becomes a 400W Buck if they choose me to do it
sounds odd but only add about 5.5mm Carrier diameter to fit a 5. cell

I meant 30A sorry. 50A would be complete overkill.

BTW, Lexel, are you still selling the Haikelite MT07S/MT09R driver?

I would like to buy it, so I can compare it to the TA FET driver for the MT09R.

Also, what are its specs? Would like to know.

I am still selling those

I have here very unpleasant measurements of original MT09Rs
used full VTC6s
XHP35 HI NW 4000K 246k stock
with D4 5000K NW from kaidomain 289kcd which is just LED swap 17.5% more output

The CW I have from another person is totally crap measured stock
only 163kcd
I reflowed just half an hour ago the LEDs for this light and need to make drivers
then I can tell final measurements with my driver @7A

How is the XHP70.2 version for output though? Is it crap or not?

We installed lexel mf02 driver on my astrolux mf02. Its very nice. Thanks lexel.

Is it running on XHP35 or 70?

Xhp 35 nw… we tried to remove the bezel to swap higher bin. It was glued well… so the light have a stock led…

you notice any different in brightness or throw with Lexel driver?

my bezel had weak glue and i managed to open it easily.

Subscribed!

first MF02s were glued with blue weak stuff
now its some white strong stuff, but not nearly as bad as MF01 red stuff

Now MF02 is glued Red stuff too.
From 6 pcs I opened only 2 bezel.
