Characterized by its low profile and shallow recessed depth, Limburg is made of hand-blown 3-ply opal glass in convex or flat configurations. Its housing measures just 5 1/2 inches deep to accommodate shallow plenums and is offered in three sizes: 9-, 12 1/2-, and 16-inch diameters for the convex version, and 10-, 14-, and 17-inch diameters for the flat version. The fixture takes multiple fluorescent lamp options and two finishes are available for each glass style.
