The Tolomeo Classic Lamp without Base by Artemide combines the advantages of LED technology with those of the Tunable White technology, enabling numerous variations of white light to be obtained, with different intensities and varieties of color temperature, with a range from 2,500K (warm light) to 10,000K (cool light). It features fully adjustable, articulated arm structures in extruded aluminum; joints and tension control knobs in polished die-cast aluminum; tension cables, internal tension springs, and external tension control cables in stainless steel; and a tiltable diffuser in aluminum with an incorporated touch dimmer and color changing control. The fixture rotates 90 degrees in both directions, and the base is composed of weighted steel with stamped aluminum cover. The table in-set pivot and table clamp come in die-cast aluminum. A switch is on the lamp holder body.
