Here are some pictures for those you looking to build your own. The regular (non-HP) version is pretty much the same, so you can use these to guide you with it as well.
This driver is awesome in the 1405. I've been playing with one of RMM's four layer buck drivers set at five amps in a 1405 for a couple months now and the driver has held up flawlessly. The four layer MTN MAX combined with a dedomed XM-L2 in the 1405 lights up the treeline out back of my house at 500 yards easily. I'm guessing it will do twice that range but I haven't confirmed that. I've also put one of RMM's two layer MTN MAX drivers at 3.5 amps into a mini mag running triple XP-Ls. That was a cool little light.
That’s cool! I am waiting for my parts from Richard to arrive but I am going to push the dedomed S4 2B at “only” 4.5A for reliability concern. How much candela would you expect at 4.5A?
I think I’ve got it working, but next time I’ll just order the completed driver. I can deal with all the caps and tiny resistors, but I hate these components that have the pins under them.
