You do realize the 520nm diode needs 7.3volts.
A simple linear driver will not work if you are planning on using a single 10180 cell.
You’ll need to use a boost driver.

I picked one up on Amazon. Should be here next week.
Here is a pic of what I have planned.
I will have to open up the inside diameter a bit on my mini lathe before I thread it.
Does anyone know the size of threads on the back of a 12mm module?
I’m trying a micro build where the module just threads right to the body of a 10440 host.
I’m guessing they are M11x .5 but I can’t find my pitch gauge to verify.
