This is a cast brass wall light with arm.  We’ve also added a 10 inch brass cover to dress it up a little.  The light measures a total of about 12 inches long and will extend down about 7 inches.  The triangular mount plate measures 3 inches on each side.  There are three mount holes.  Because this mount plate will not cover most standard junction boxes, we recommend adding our 6 inch brass plate for an additional $20 each.  The light weighs just over 4 1/2 pounds.
