I want to replace a wall mounted light fixture. When I took it off the wall I realized the box behind it was a rectangular 1-gang:
The previous circular light was mounted to the wall with three screws into drywall.
The new light I bought is an LED ceiling light with a cross bar:
The screws that came with the cross bar don't fit in the boxes screw holes, and I'm a bit worried the sheer forces on smaller screws might be a problem.
Did I buy the wrong kind of light or is there an adapter I can use? It seems like even "official" wall sconces need round boxes these days, so I'm not sure what to do.
Just to explain the "why" of this, a traditional wall sconce wouldn't make sense here, it's a narrow hallway with flush wall-mounted lights.
