Are there other ways to mount an exterior lamp to a cinder block wall other than:
a) chiseling out the cinder block and mortoring a box into the hole
b) surface mounting the box and spacing the lamp bezel away from the wall with a wood plaque
A "fixture pan" is an electrical box that is about 1/2" deep and will fit under the canopy of most light fixtures without spacing.
There was a recent episode of Ask - saboteamos.info that dealt with a similar issue in a brick wall, though they did chisel out the brick. Watch it 0nline, it may help you out.
Thanks, I appreciate the help & will watch that TOH episode. If I can fit the box under the lamp bezel it sure will save some steps.
