That triple 219c could handle a lot more current (with more heat, of course). Have you considered a sense resistor swap in that 5A driver? You can dial it in pretty nicely.
I haven't on this light. It's kind of a parts bin light, with a spacer made out of a thin walled copper pex line plug, so I didn't want to throw too much current at it.
I did use your guide to attempt a sense resistor swap on another 5A driver when I was trying to use an SFS75 in the S8. But I only have a soldering iron and wasn't entirely successful. I ended up deciding I didn't like the SFS75 anyway and abandoned the idea.
Yeah, I hear you. I also struggle with resistor swaps with a regular soldering iron. It's a pain.
