CATANIA's housing elements are precision-machined from billet aluminum, then satin anodized for a clean understated look. Spun aluminum disk is satin anodized to match housing, and produces a corona-like effect, while the translucent acrylic cylindrical lens creates a soft ambiance. Prismatic end lens adds an illuminated focal point. Optional flashed opal end lens totally conceals the lamp image. All hardware is stainless steel. A 24" trim disk is optional.
