What is the matter with PWM dimming? Would it be resolved by using a higher frequency for PWM? The main reason you use PWM for dimming LEDs is because DC dimming (or filtered PWM) causes color shift. By using PWM, you can drive the LEDs with the same current, but effectively switching them on and off. Driving LEDs at different currents produce slightly different color outputs.
