I need automatic porch lights as I keep forgetting to turn them on and off. My light body is frozen. I've read the reviews and the Q&A and several people have said that it works great in matte cases. Unfortunately it isn't. I used a lightbulb during the day. I flipped the switch on, the light blinked 4 times then went off. So far so good, I thought. Once it got dark outside, instead of turning on and staying on, the bulb turned into a strobe light and just started blinking constantly. The light came on, the sensor thought it was light outside, and the light went out. Then when it was turned off, it sensed that it was dark outside and turned it on again. etc. which effectively turned the lightbulb into a very annoying strobe light.
