By the way, one hint from me. The electric bill in California is quite noticeable. I've managed to save about 20% every month after installation of motion sensors with timers in place of regular light switches for non critical indoor lights.
Just curious, but are these motion sensors hooked up to incandescent lights? It's too bad that CFL's don't like being turned on/off repeatedly and have a shorter lifespan when you do so, particuarly since the better quality CFL's aren't cheap to replace and are a pain to dispose of so you want to make them last as long as possible.
