I can't understand what all the fuss is about, run your LED with the correct resistor, switched by the mosfet (or BJT your choice) and change the PWM duty to alter the brightness - Done!
So if I only need to connect just one colored 10 watts led per driver do you think it's better to just have R1 and Q1?? Something like that?One thing I noticed is that with a low width PWM (when the color should be off) it blinks a little. What do you think about that?
