Hello Hjourzt,
have you had progress on your issue? I am curious, in recent projects that I have done (data) on commercial sites the lighting controls you were talking about are becoming popular.
There are DMM's to be had for about 100.00 bucks which will count frequency up to 500k - if you own the equipment you are using you could conceivably go back to a site and make a measurement.
I for one would be curious - got out of ENG years ago and do not have an easy way to replicate your situation.
