CONSTRUCTION The Geometric Series offers a variety of construction methods to meet specific application requirements. Each manufacturing method has inherent benefits specific to the luminaires’ appearance, form and function. • Spun – provides a seamless, single piece     housing – ideal for round luminaires • Formed - made from a single flat piece of    aluminum formed and continuously welded to    produce crisp edged rectangles or squares • Extruded – constructed of rigid aluminum    panels allowing for thicker walls and    increased durability
