I have CFLs on motion sensors in the garage and the only PAR I have, outside (the rest are softer light) and I don't see a problem. The triac should be driven to saturation, unlike some dimmers. The dog walking around does trip some of the motion sensors but they are arranged so they don't bother you in the bedroom. I masked the window of the one in the bathroom so it doesn't "see" the dog. It is under the vanity counter.
If I have the real lights on it disables the MD as does daylight.
The lights in the bathrooms are just short pieces of rope under the toe kicks and the hall lighting is rope in crown, about 4" below the ceiling for soft indirect light. In the living room, dining room and kitchen it is rope on the train tracks (another story I guess)
