OK this may sound like a silly question, and I think I have answered itself by searching, but if someone could chime in and let me know if I'm on track, I'd appreciate it.

Lets assume I had a single Phlatlight SST-50, and I wanted to drive it at 3A from a 9.6V NiMH battery pack.

If I were to get a Shark Buck 3A model, connect everything up and heat sink everything, would the shark buck deliver whatever voltage that the LED required to get 3A flowing through the circuit?

What I have read so far, leads me to believe the answer is "yes", and that my LED would not be damaged in the process. Am I on track?

I realize that other things may limit whether this is possible like wire gauge and the ability of the cells to deliver enough current to the driver. Is there anything else that I might have overlooked?

Thanks for helping me to see the light
