I'm going to be putting a floodlight on the outside of a garage. There isn't currently any light in the location. The exterior is clad in aluminum siding, and possibly some foam board insulation behind it (not sure yet, as I haven't taken too serious of a peak). Any recommendations on the best/easiest way to mount the junction box? Should I mount the box on the plywood sheathing, and then bore an appropriate size hole in the siding? Or is there an exterior flush mount round box, made for this kind of application, that can attached directly to the siding (with the screws going thru all the way to catch the sheathing)? Thanks.
