Actually, it is quite possible that dargaud saw frequency modulation. It is possible to over-power an LED but to pulse it such that the overall average is within the power limit. This is more of a guess on my part as I haven't played with overpowering LEDs much, but I would guess that the manufacturer had to power the LED so high (to get bright enough) that the frequency rate came within dargaud's visible range in order not to have the average power beyond the limit. I also wouldn't hold it to the maker to presume that anything above 60Hz is fine.
Odd about the dimming the light that way; IIRC the LEDs I've used can be extremely dim with low enough voltages without having to flicker it on/off.
