Nama saya Chris (I had to learn Indo at school)!
Any preference in output? What are your input numbers? There are a few drivers you can buy for this task depending on how much you want to spend? The XHP50/70 will be the brightest and probably the easiest to work with. How big are the LED boards inside? If those maglights are running 4s 18650 using some thing like an LD3 driver would work very well. I am not sure about running multi XHP35 because they are sensitive to high amps. Some one with more experience then me will have to chime in? You could also use the LD3 to run 12v XHP50/70 or you could go with a direct drive setup.
