:huh: PWM can be easily seen by pointing your light at your shower head, with water running of course! The water may look like separate drops depending on the PWM frequency. My Pelican 9410 does use PWM for the lower mode, but it is of sufficient frequency that it's only noticeable in the way described.
Try this with your lights, let me know what you see.
A ceiling fan works too
The explanation that was given for the blinking on the Quarks involved graphs and such to show that, while it looks like PWM, it has a different signature on an oscilloscope (or whatever that neat machine is called).
