>As for PWM -- do you have any source on this? Well, mostly just "duty cycle" related. If you're pulsing the LED half the time (50% duty cycle), for example, you can pulse with twice the current you would normally use if it weren't pulsed. Then you control brightness by pulsing for a lower percentage of the time.
