Hmm. Sounds like the sum total of data is 1) your friend, and 2)
stuff you've heard. I'd like some evidence the "problem" is real, not
imaginary and not hearsay.
FWIW, if your friend gets migraines from CFLs and other flourescents,
he must be having them very, very frequently. I've noted that almost
all stores in my area are lit with one or the other. So are all the
hotel rooms I've used in the last several months. These companies are
doing this because the economic sense of it is absolutely obvious to
anyone with a working calculator.
While I can easily detect flicker in ordinary flourescents using a
trick similar to Chalo's, I can detect no flicker from the CFLs in our
house, and I've tried. I'm not sure why that is - I'd have expected
them to be driven at 60 Hz, but apparently they're not. It's possible,
I suppose, that some brands flicker and others do not.

So we can take steps toward avoiding another energy war. I've had one
nephew sent to that big sandbox, and I have one close friend still
stationed there. I know you feel no need to inconvenience yourself
over this war you love, but I feel differently.
