I'm replacing some bricklights in a retaining wall. I removed the old ones (little more than piles of rust) and the remaining holes leave about 1/4 to 1/2 inch of space around the new light boxes. How should I secure them? It seems to make most sense to just place mortar around them but I'm not sure if that's best.

(I know brick lights are very problematic and I know they don't usually last. But the last ones lasted almost ten years before they stopped working -- I'd be thrilled with that again.)

Thanks

Replacing brick lights how to secure.

Since the hole now is bigger, I think the best way is to put mortar like you say but the trick is to put a sleeve inside, that is the requirement.

Thanks. What kind of sleeve?

It is a type of sleeve usually rubber or plastic so it serves as insulation. The outside wall is firm within the concrete; the inside wall is a bit larger than the light fixture arm. The main idea is that electrical devices do not touch concrete or bricks. I bet the whole reason is for insulation.
