The Devonshire outdoor sconce has a charming arts and crafts design with cylindrical seedy glass and a Matte Black finish. Lighting professionals generally agree that outdoor wall sconces should usually be placed at eye level, approximately 65 to 67 inches above the ground or porch. When installing 1 outdoor wall lantern on one side of your door, it should measure about one-third the height of the door. When installing 2 outdoor wall lanterns, each lantern should measure approximately one-fourth the height of the door.
