Do not buy these!!!!  They are so cheap.  What they consider shades, come rolled up like scrolls with 4 pieces of metal.  The "shades" have several plastic clips on top and bottom that you have to click on to make the shape. They took me over an hour to get the correct shape.  The bulb sits on top of the metal frame with no protection around it.  My box came with enough nuts and bolts to put together a tractor trailer but no directions.  Wayfair told me that I have to pay for a new box if I don't have the original one  and then they want to charge me the $10.00 for the Fedex return!
