I am going to build a light which will run a single xm-l emitter.
I am primarily concerned about battery compatibility and run time rather than extremely high lumens.
I'd rather have a single output mode.
I will primarily use an 18650 battery, but if it comes down to it, I want to be able to use 3AAA in a pinch or possibly 2xCR123 with an adapter tube.
I was thinking about using a single 1.4amp amc7135 driver. Will this work with the above battery configurations? Will I need some kind of buck/boost driver instead?
Thank you kindly for your input.
