A friend of mine is getting forgetful in her old age and is always leaving the porch light on all night. I'm looking for a PIR motion detector that will screw into an existing lamp socket. In other words, not one of the dual floodlamp types that you need to mount to the wall. I've seen socket adapters that use photo detectors to turn on at dusk and off at dawn but have yet to find a motion detector in that type of package. I know I could hack one myself, but I hate to cut into my beer drinking time if I can buy my way out of it. Any ideas?
