I am replacing my old outdoor lamp. The new lamp has an X-shaped mounting bracket. However, my outlet does not have an outlet box (see pic), or may be there is one but the stucco has covered it. There is just a horizontal metal strip that I can see.
The old lamp was screwed into the screw in the center. However, the new lamp's bracket does not have such a feature.
Is there a way to install the "X" bracket to the horizontal strip? I don't want to break stucco to install the outlet box.
