-I will change its duty cycle to adjust its appropriate brightness.
-It has 19KHz frequency, I don't know how much is suitable. Audioguru was saying that a LED swithing less than 30mS will start dim light. If we turn the LED on 30mS and turn it off in other remaining time then we get same high brightness but but from less current drain (turning OFF the LED maximum time). So worrid about output frequency.
-I hope on resistance of the darlington will give series resistance for the LED. Analysis needed.
I can post .asc for LTspice too.
Regards
