The heat sink of the Rc Controller Power Supply unit is very small 9mm X 9mm and weighs only about 3 gram.

Isacc, is it possible to pulse the LEDs to reduce the power consumption and heat load? Something like 50% duty cycle at one or two Hertz?
Does the LED driver circuit reduce power automatically at a critical temperature?
