Put light together, plugged it in...did not work!  My husband who is very handy took the switch apart, the light socket apart, did a bypass on the switch and still the light did not work.  We finally decided to take the entire lamp apart after reading the other reviewers who complained that their lamp did not because the wire was spliced! After taking the lamp apart found the wire had been spliced midway in the arc!!!  My husband repaired the spliced wire and the lamp works but we were so disappointed that the lamp should of been working after the quick assembly.  Instead it took 2 hours of our Sunday afternoon to figure this out!  Assembly was easy and quick until we determined that light would not work.  Directions came with the lamp.  Agree with many other reviews that the shade is cheap.
