I need to hang a light fixture from my ceiling some distance away from its electrical box. The fixture weighs less than 10 lbs and my ceiling is made of drywall.
I'm generally comfortable using drywall anchors for shear loads on vertical walls, but I'm unsure about how much weight the various designs of wall anchors can handle for pull loads. I've done some internet searches but haven't found anything definite.
Can someone tell me how much pull-force the various common designs of wall anchors can handle?
EDIT: To clarify what I am trying to do, see picture below. It's not my light, but it illustrates the concept.
