Well I came across some high current drivers today that should do the job of powering the XR-E LED’s. They are capable of running a string of 3 at 1A per led, but I am only going to run 2 LED’s per driver. So thats two drivers in total. Each driver is able to be dimmed individuality, but in the interest of simplicity they will both be controlled by a single knob.
Also dug around and found a suitably size box to mount the parts in, cables and a 16V AC plug pack transformer.
Its all slowly coming together.
