Konstantin Grcic conceived the Noctambule as a study in transparency and structure. Hand-blown borosilicate glass cylinders, each precisely formed, are stacked into a column that reveals its LED light source rather than concealing it. Illumination becomes form. The system is genuinely modular. One cylinder or four, capped with a cone or dome for directed light or left open for softer diffusion, the configuration determines the atmosphere. That flexibility is architectural in spirit, inviting considered decisions about proportion and presence. Hand-blown borosilicate glass cylinders Integrated LED at top and bottom of each module Dimmable via pedal dimmer or ceiling rose power supply Available as a standing or suspended fixture Multiple height configurations through modular stacking Grcic, whose Munich-based practice KGID has long operated at the intersection of industrial rigor and cultural inquiry, approaches each object as a question rather than a solution. The Noctambule does not decorate a room. It reorganizes it, drawing the eye upward through a column of glowing glass that shifts character with the light level and the hour.
