Key Features
Accentuate your interior spaces with artful angles of the B-4 Table Lamp from GUBI. A 1945 design by Greta M. Grossman, it uses a series of angled panes suspended in a rectangular wireframe to screen a single socket at the end of a slender cord. Each angled panel can pivot outward to dispense a greater share of light around the fixture, offering a stylish modernist attitude to the fixture’s surroundings while blending practical illumination with a sculptural presence.
In 2001, Jacob and Sebastian Gubi took over their parent’s furniture business, transforming GUBI in to an internationally recognized design house for lighting, furniture, and accessories. Based in Copenhagen, Denmark, GUBI is a purveyor of timeless and emerging designs, many of which are iconic and can be found in permanent collections around the world.
