After buying one very similar to this at Lowes, I got it home and out of the box , not very impressed by the craftsmanship ,only because of the price. I put it up in a pinch, I was even more depressed once it was up, the cheap plastic really cut out a lot of the light. This was why I kept the big ugly lamps in the first place, Anyway I took it back and made this one. The dimensions are 52 long, 22 wide and 6 inches tall. Save some cash and make your own or let me make one for you. Of course all options and sizes available.
