The Halo Table Lamp’s ingenious design consists of glass, metal, & marble parts. The double glass pendant (our Halo design) rests on a metal plate, which is in turn balanced on cone-shaped metal attached to a round marble base. The lamp is connected to the outlet by a fabric cord that also carries the tube-shaped metal switch. The switch was specially engineered to be controlled by touch: through touching it, the lamp can be either turned on or off or even dimmed to the desired brightness.
