Hmm, so what makes leds have an issue with higher frequencies then, I'd
have thought this was of no concequence , but maybe its to do with the

I've driven LEDs (very high brightness types but not full on mental Cree
types) at upto about 10kHz with no apparantly ill effects. At that frequency
there will be no strobe effects that a human could detect.
