On a positive note, these lights are terrifically good looking on the wall. Quality is generally good and they have a sense of class. Downsides. 1st - Delivered late. 2nd - give the prices I would have expected the connection wires to have been stripped back (instead I had to faff around cutting through the cord). 3rd - again given price (paid partly due to aesthetic appeal) the lights did not come with fixing screws, which I find very disappointing. 4th - I think an enclosed fitting instruction re-confirming need for trailing edge dimmer would be appropriate.
