I found these lamps at a customer's house. They sure look nice from the front, but a side view shows that there is no direct connection between the fixture and the box.
The lamps had UL labels- but my knowledge of UL standards made me doubt that UL would accept such a product...and, no real surprise here, the UL label turned out to be counterfeit, with a non-existant "file number" on it.
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.
