Anybody know where to get this kind of thing for cheap? So far, all the replacement modules I can find cost as much as an entire new fixture (light sockets and wall plate included). I guess those cheap metal parts are nearly free and you're paying for the electronics.
I've got an outdoor security light that is showing sporadic behavior. Replacing the cadmium sulfide light sensor cell helped a little but was not a full repair. As I was playing around I discovered that when the light was stuck in the wrong position for no apparent reason, tapping gently on the relay on the PCB would cause it to correct itself. So I pulled the relay and tested it on the bench. It's rated for a 24V coil drive and I tested it at 12V. It clicked very reliably on 12V. So my theory is that some other component on the board is preventing enough power from reaching the relay coil. These things are pretty cheap, so that's pretty much a death sentence for the old PCB. Easier to just buy one than to try a repair.
But I'm perplexed that I can't find one for a few bucks.
