The original. The design that set a trend in the lighting industry. But never equaled for the combination of design, performance, and quality provided by Classica. The difference is in the details -- a unique, slotted reflector to smooth and control perforation brightness while providing a widespread, efficient distribution of light. Classica's coordinated use of aluminum extrusion, perforated steel, die-cast joiners and end caps, and acrylic diffusers deliver a superior indirect lighting solution. U.S Patent No. D363,805
