I'm not sure which forum is best for this topic but here it is in electrical...
I have a detached 2-1/2 car garage. The facing of the garage is ~3/4" thick deco-stone applique mortared onto mesh lath, and then grouted. The contour of the stonework is quite irregular; below you will see my iPhone perched on a ledge to give you an idea.
I would like to add some supplementary lighting around the garage door openings. Some location options include at the keystones, in between the window and left hand side door, or central (underneath where you see our Christmas wreath currently hung).
My wife favors the central location although I am not 100% sold on this yet. She imagines a wrought iron-looking decorative lantern fixture to match the faux carriage hardware on the overhead doors.
My question here is regarding the best way to mount such a fixture to the irregular stone surface. What's the best/right way to do this? I was thinking about building up an area with some mortar so that it was in fact flat, then mounting an outdoor box to it. i was also thinking that i could simply use NM conduit w/threaded fittings into the box and not securing the box at all to the wall–– the conduit would hold it in place. This would only entail a ~1" hole in the stonework. I'm not convinced of this idea.
Any ideas and/or thoughts on mounting location and attachment method appreciated.
In just about any mounting location, the interior area directly behind where the box would go is open for access.
I have used google images and found a couple of photos of this type of application and honestly I think that having such a gap around the mount is a little bit hack-ish...
