I'm not 100% sure. But, the motion sensor probably increases the power
to flourescents gradually, instead of instant on.

Or possibly uses some kind of SRC widget (or similar) that is half-wave
rectifying the power. At least, that's my recollection of an explanation
I got way back when. Dimmers do things like this too - hence their poor
performance with flourescents.

I'd get a single incandescent to run off the motion sensor and separate
the flourescents from that circuit. Do you want the motion sensor to
operate the lights all the time?
