Magistretti designed this lamp using a section of a sphere as the diffuser, topped with a second geometric piece from the same shape, mounted in reverse with its concavity facing the ceiling.
Cetra is a sculptural suspension lamp that combines pure forms interacting with light through different materials—diffusing, shielding, or reflecting it.
The two metal hemispheres are lacquered in white. The upper half conceals indirect emission, while the lower section holds the opaline glass globe that softly spreads light throughout the space.
The entire collection designed by Vico Magistretti demonstrates how good design results from the synthesis of form, material quality, and technological coherence—bringing quality to everyday spaces through simple gestures.
