Hey guys and gals...hope everyones weekend was well. Got a new client and they want some cast deck lights mounted to a dry stacked wall. The wall is about 6 ft high then capped off with a brick topper. Unfortunatly to get the effect we want the lights would need to be mounted directly to the walls and not the brick. I have open accsess to the back of the wall to run wires and it just so happens the trans is post mounted behind the wall. Have any of you mounted lights to a wall light this... Its similar to flag stone and just stacked. Little wiggle room to get wires in but hanging the lights has me baffled.
