The lamp evolved from the concept of hanging a light source from a transparent structure, creating a certain volumetric form. There is almost an x-ray of the lamp itself, allowing only the light to emerge.
A single halogen source creates a dual light effect: an indirect upward emission and a diffused downward light incorporating a RED filter (blue is no longer available from Artemide although we can source any colour filter. Please inquire for details and cost). The light illuminates and colours the central rod, making it like an incandescent thread that is the true luminous soul of the lamp.
