I have some older Luxeon high power LEDs and bought some drivers (spec below) to power them. They work fine for what I need. However, I am going to be controlling these using TIP120 circuits (one to one) from an Arduino and it occurs to me that I don't know if I should be controlling power flow to …

Should I control the high power LED or its driver?

Thanks for the replies!

Good point about destabilizing the circuit - makes sense now that you point it out.
