I’m still doing research on how to do this with the V2… missing those 4 wires throws me off a big time :frowning:
Maybe I should just send the thing to Lexel…

I did explain here how to modify the MCPCB to 2S/9P

Received mine today - thanks, Lexel!

Still saving up for a decent soldering station though, so it might be a while before I check in here again for advice.

I just unscrewed the bezel, and removed the brass contact ring from the inside. Now I’m wondering if I can just pull the grey wires off the MCPCB, or do they need to be unsoldered?

Also, I don’t understand what’s going on here:

Can someone please explain (for dummies)?

you can unsolder the leads from old driver

if you have 6 its V1 and you can solder 3 of each kind to new driver

if you got only 2 you have V2 and you need to modify the MCPCB as well
cut in 6 places as shown
and
wiring the red circles together
wiring the black circles together

Please correct me if I’m wrong - if I understand correctly, for V2 you basically sever the traces on the star that connect the LEDs where the straight black lines are, and the squiggly black and red lines are where short pieces of cable are soldered onto the star?

Since this is my first ever project, I’m now wondering whether I should dare to rewire the LEDs, or whether I should keep the V1 configuration. I’m assuming I can just make the cuts with a carpet knife?

Thanks for the help. This is all new to me, and I really want to get it right. Got my rework station today, but I’m not even sure if the solder that I bought has a sufficient diameter … I’m eager to get started though once I’m sure I understand everything! :slight_smile:

for V1 star no changes needed, not even opening up the head front

for V2 6 cuts on the marked lines are needed and all same color dots need to be wired to the driver adding bridges and 4-6 more leads (3 or 4 pads on driver), as you should increase the gauge of the wiring by 3 as the current goes up 3 times compared to V2

each wire should share 6 diodes current balanced
you don’t need to follow my painted wiring

I contacted banggood and they are supposed to be sending me a v1 mcpcb.

I wired according to diagram and all leds are working except for 2 leds at mateminco label when you hook up positive wire for the two leds the 2 at mateminco come on an all others go off.If anybody has any ideas let me know.

In the pcture on the bright area the traces are not really good visible, maybe the real trace is there different and another ground wire needed


Looks a mess but got all leds working.

Everything was working nice put it in light box with fresh charged vtc6’s and got 15000 lumens . But something has went wrong light still works it ramps up to about 4500 lumens the shuts off if you let go and ramp down it will come back on at 4200 and ramp down to moon.

Sounds like the FET died or its signal connection is broken
Should go to pin 3 of MCU

Yeah been gone gonna check it out tonight.

Did some checking there is zero voltage on pin 3 when light is on .when you ramp up and light turns off or you double click for turbo there is 5.11 volts on pin 3.Anybody got any idea.

I changed the fet and light is working now nearly 17000 lumens on turbo .

I got today also a light from Canada v2, so modding the MCPCB as well
I connected it the was it lights up with central connection, but I will place the main current cables to the spots where the resistance is optimized

What size wire did you use ? I used 20 awg . I bypassed all te springs on the driver and carrier and got 19100 lumens on startup, it stepped down before 30s with a 60c temp setting.

I wired the briges up to connect 2 leads for V+ and V-
I used 0.35mm² for the small bridge wires, as they only carry one 2S LED pair
so if I get this straight not reducing the mm² to the driver I would need 9x0.35mm€ so 3mm²

The leads to the driver I can go with 2x2 1.0mm² or barely fit 1.5mm² leads, so 2-3mm² each combined wire


I have now his light fully modded
leads are soldered to spots to get lowest resistance
