The 2 Pack of Builders' Choice collection 1-light wall-mounted lantern is made of cast aluminum in Matte Black finish. This material is a good choice for exterior lighting since it does not rust and resists corrosion. The classic design of this fixture lends itself to many architectural styles. Complementing its clean design, this lantern features Clear Beveled glass panes. Beveled glass has edges that are cut at an angle for a traditional look. The bevel adds definition to the fixture and has a prismatic effect on the light.
