Silhouette is the name of this black table lamp in a classic design - apart from one small detail; The top of the lamp is floating in the air.
What makes this lamp floating is the integrated levitation technology. It consist out of electromagnetic components and a sophisticated control system. Next to the fact that they employ the very latest LED technology, the lamp is low in power consumption too. With a touch of your fingertip, the lamp can be dimmed to the intensity you require.
