Ive discovered that some cfl bubls work with the sensor (550 watt and under home depot about $20) and some flicker when the sensor shuts off the light. IF I use incandescent no problem or if i manually shut off the cfl no flicker. my problem is the cfl bulb that works I found in the house with no package (lol I dont know why) so I am not sure how to buy another of that brand. All the others Cfl bulbs I have basically instead of shutting the light all the way off the light constantly flickers sort of dimly. I notice on the motion sensor package it states for use with rapid start compact flourescent bulbs only! I found some new cfl's bulbs we had at the house which stated new fast start technology. however they flicker also when the sensor tries to shut them off.. can someone tell me why they flicker and wont shuttof when the sensor shuts them down and is fast start the same as rapid start? if not where Do I find rapid start bulbs? Any help appreciated!

I am replacing a light fixture in my bathroom. When I installed the new fixture it does not work, and now neither do my kitchen or patio lights. The people who lived here before me had the old fixture wired up so the neutral wire (aluminum wiring) was connected to the gound wire to complete the circuit. If it is done this way everything works. If it is done the correct way, nothing works. Is it safe to connect the neutral and ground wires together in the new fixture? What could be the cause of it not working when hooked up correctly? Any info is greatly appreciated. Thanks!
