I'm trying to design a constant current 3amp source for an led. I haven't found much searching around but a few things.
unless someone has a better circuit, I'm going to try to build this here

What specs (exactly) change the current value?
If I want 3amp output, how close to 3amp can I get without worrying about going over?
