Porch light install question


The mounting plate is larger than the existing box and the holes to secure the light are about a bit less than an inch outside the box over the concrete wall. Would it be advisable to sink anchors in the concrete to mount the light on? The light itself is secured to the plate by 2 other screws from the back of the plate out through the front of the light housing.
Thanks.

I usually drill holes in the mounting plate that will line up with the box in situations like this. I don't like to drill holes into the house unless it is the only way.

Installing anchors is O.K.. But, check the electrical parts area at a hardware, HD, etc. for an adapter plate that screws onto the existing box. The plate will have numerous holes and slots in it, so you'll find something to match the lighting fixture mounts. If the fixture isn't tight against the wall, you can always add a wall anchor or two to fasten the adapter plate tighter to the surface.

Sounds like a missing adapter, plate or bar, that mounts across the standard threaded holes in the (octagon?) ceiling box. And then adapter has holes or threaded points in it onto which to mount the fixture. screws. If it isn't a standard North American (or is one of the older sometimes slightly smaller octagon boxes) an adapter could be altered or fabricated out of a bit of metal. Drilling holes in concrete seems to be rather an extreme measure unless absolutely necessary; for example if the electrical mounting box is insecure/loose. BTW I offered to replace my daughters corner roof light with a motion sensor fixture. When got at it there was no mounting box at all for the existing light! So had to finagle an octagon box into the soffit and mount it securely to mount the replacement fixture!. GD cheap original contractor!
