So i was wondering what driver can power all 23X M140 Japan Version Diodes at the same time, or will 3X M8 drivers work to power 7 diodes at the same time 🤔

You won't like the factory lenses but you can power it up for fun.

You can use this driver and power the three rows of 8 diodes in series/parallel.

The factory ribbon has K for cathode and A for anode, I cut between each line and solder on wires, you can then power any string of 8 or all 3 strings together.

So each string of 8 in 3 parallel strings around 35V @ 1.5A for each string so if all 3 strings in parallel you can go to 4.5A

Thank you this is amazing i have the same diode block 👀
The CC for Amp, And the CV for Volt.
I'm using mirrors and it will be 1- beam and 1X lens i hope, i will post pic's tomorrow or when i get the driver :alien:

I have bought 4 of these drivers and one came already turned all they way up, so test the driver on a light bulb, don't power the driver without a load connected.

Use an incandescent light bulb as a load and set the driver for say 20V then when you connect your laser diode bank you can simply slowly adjust it up with a volt meter in parallel and I use an inductive meter to check/set the current limit.

If you use the default mirrors you can get a perfect point not far from it i post some pics tomorrow its amazing
