A surface-mounted wall bracket for spotlights that are otherwise installed in suspended ceilings.
You can either mount it with a screw or stick it to the ceiling with Nano Tape, as I did. Holds wonderfully.
I have used the following spotlights for this. However, they should also work with most other models.

The author marked this model as their own original creation.
