You are at the right place. Lexel makes them himself. He will contact you in the next day or so. Maybe today.

not possible for that light, the driver cavity is too shallow and there is no high current buck atm

I have a report of a DOA delivered driver

It was within Germany and he sent me the whole light

The driver was fine, just the new thermal enhance design does not allow a bad soldering job on the LED+ terminal

here clearly can be seen that the wire solder blob also touches the ground viases that are about 0.75-1mm next to the pad, the buck chip detects short and stops output

best is to solder the wire straight up or 180° rotated pointing to the capacitor so the ground plane is clearly visible and no short risk

Any idea how deep driver cavity is? I think there are some good coils that are 3-3,5 mm height.

you can not pass 12-15A through a 3mm high coil

I know that coil characteristics degrades while heat increase so there must have some addition over threshold, but how about Coilcraft XAL7030 series? Are those still to weak?

Definitely interested in the BLF Q8 XHP 35 driver. May need 2 or 3 of those. Where do I get the MCPCB for that?

The stock MCPCB is fine. Your problem is converting the light from 4P to 4S. Not simple when they dont use carriers.

How is that even possible without carriers? Lexel how did you get that to work?

You have a driver with 4 pads that make contact with each battery separately. Then you permanently fix the battery tube into place so the battery ends line up with the driver pads. Then you modify the pcb in the tail cap. This will supply 12 volts to the driver, but you have to load the batteries through the tail by removing the PCB each time. It’s a pain to swap batteries, but it works.

you can also build a rotating tail board with 2 pins that uses a bolt to hold to the tail cap

MF02S MCPCB is custom, no way to buy that stock on normal shops

Drivers are no problem

I want some 20mm XHP35 or 12v XHP50/70 drivers for two of my C8s with 20.8mm driver socket.

Already PM’d you a few days ago.

 

Searching for High CRI leds since 2010...

 

Has finally gotten to the bottom after 10 years of delving deep into that rabbit hole of them high CRI lights...

 

High CRI, high quality lights doesn't need to be expensive, or is it?

How are you going to feed 12v in a C8 size light? Double battery tube and run 4 18350?

I’d prefer a boost driver for single 18650. I’m running one in C8 with single 18650, but the size isn’t right (22mm vs 20mm) and the mode switching doesn’t work properly after sanding down.
So I just want to run C8 with some 20mm proper.

Okay, your asking the wrong person. Lexel doesn’t have any boost drivers. You need to talk to Richard at MTN E.

Hi Lexel,

Could you PM me with a price please?

I’d like to order a buck driver to replace the stock one in my MF04S, with Berylliumbronze springs and gold plated button soldered and Anduril flashed onto it, shipped to UK please.

Thanks

Hi Lexel,

Do you have driver to replace the one in Convoy M3 (XHP70.2, side button, Ø26mm 1S battery)

Thanks!

As I know are his boost drivers not ready yet.
That means, he has no driver for a 6V LED in this flashlight, if you dont want to use 26350 batteries.

Hi, do these buck drivers work without the e-switch?

I’m looking for a 3S (12.6v) buck driver to go in an old C cell maglite with an xhp50 6v.

1 switch. Power is either on or off. No press and hold.

Thanks.

EDIT

According to this post from Lexel, the answer is yes, if the components and software can be changed.

Would you be happy to sell such a driver?

I always sell drivers with e-switch or tail clicky assembly depending on how it is ordered

Thanks for the reply.

If you sell a driver configured for a tail clicky, how does the UI change? There is no press and momentary hold option in this config, so … Narsil and Anduril require a hold facility to work to full spec. Do you just omit any press & hold functionality or replace it with something else?

Lexel provides firmware accordingly - NarsilM and Anduril are e-switch versions. You have to use clicky firmware for clicky lights, like Bistro, A6, etc.
