Great... drywall anchors failed.

I attached a wood beam to the ceiling 2x4's and then attach the lights to that. I could swing off of it if I wanted.

I wonder if the drywall is actually plaster. If I use those self-drilling anchors, they crumble right out of the wall :( Big toggle bolts was all i could figure out for my lights. The ceiling seems to be made of the same crumbly plaster. I bolted the t-slot in 4 different places. Hoping the wight is better distributed since the lights are not directly in the ceiling. Had some heavy Orphiks up there for a week or two... seemed fine. Not sure about long term though...

ignore that extra piece of t-slot. That was just a test lol

Horsehair plaster, drywall, wood paneling, regular plaster in mixed layers and varying amounts of air gaps in between is what I have to deal with. The alligator anchor is the only one that I’ve found works relaibly. The plastic plug is soft, so it expands like a masonry anchor for a compression fit or toggles open if there is enough space.
