I want to put a couple of these lights on my garage. It appears that whoever designed this structure planned for some such: in addition to switched floods, there are some blocked-off boxes on the outside wall.
The problem is that all the motion-sensor lights I've seen for sale are built on round bases, and the wall boxes are duplex outlet-sized - the mismatch would let rain in. I haven't found an adapter plate or box at any local hardware stores. As a last resort, I thought of remounting the lamps and senor on a three-hole duplex-sized outdoor cover - but there isn't room between the holes.
Any suggestions? Thanks very much!
