Attach light to uneven stacked stone.

How do I solidly attach the large, flat, back plates for light fixtures to an uneven stacked stone wall?

I need four screws into the wall for each. Do I drill mortar and rock or just put two screws in mortar and skip the other two that position over rock?

I don't want to permanently flatten portions of the wall because eventually the lights will need to be replaced and the new ones may be a different size. Do I use styrofoam or something else to even the gaps in the wall?

Welcome to the forums! You may can find some rubber mounting or spacer disks in different thicknesses to bring the case into a proper position while allowing you to fasten it properly.

I saw those stone guys on DIY put lights in. They said you can drill into the stone or use liquid nails. The used liquid nails for that particular instance.

same way we'd attach signs/letters to uneven surfaces,,, ' stand-offs ' - alum tubing cut to rqd size fitt'd over the lead anchor stud.

this way the lamp'll appear to float on the wall.
