Reno,
What are the chances of being able to trace this "phony" back to the supplier?

Where would you report such a thing?

UL has a procedure known as "field reports," where such matters are initiated.
I would have loved to run these fixtures down, but I lacked some co-operation from the owner. I suspect they were picked up on a trip south of the border.
There was, other than the UL lables and a "made in Mexico" lable, absolutely no identification of any sort on them.

I forgot to mention that they also lacked any means of grounding.

I think those things should be prohibited due to being butt ugly!!

Got to agree on that. They might look at home on the walls of one of our medieval English castles, I suppose.

One has to have SOMEWHERE to hang the servants!
