The slim vertical body of the lamp is grafted onto a truncated conical base and extends with an initial cylindrical-section segment that gives way to a long terminal profile in extruded aluminium with a flanged section in which the LED circuits are positioned, thus making it possible to screen the light emission generated by the high-efficiency sources. The body freely rotates on the base for an easy orientation of the indirect light. Equipped with switch and dimmer on the cable, the lamps of the Compendium family are available in the finishes black, brass and aluminium.
