Patera 450 Pendant by Louis Poulsen is the mid-scale variant of Norwegian architect Øivind Slaatto's mathematically derived pendant, in which the positions and angles of every aperture are determined by the Fibonacci sequence and the logarithmic spiral geometry of the nautilus shell. Slaatto mapped this spiral continuously across a sphere, using the resulting grid to locate the oval opal methacrylate openings that distribute light outward through the pendant's surface. At 450mm the Patera achieves a more commanding presence than the 300, making it the natural choice for use as a single pendant over a dining table or as a principal pendant in a bedroom or living room.

The 450mm diameter produces a pendant that reads at room scale as a complete, self-contained globe — the aperture pattern is large enough to be legible from across the room, and the warm glow of the opal openings creates a distinctly atmospheric light quality in its surroundings. In a restaurant or hospitality dining context, the Patera 450 works effectively as a primary pendant where a spherical, architecturally considered fixture is the specification intent. Its neutral white finish integrates across a wide range of interior colour schemes and material palettes.

For architects and interior designers, the Patera 450 DWG drawing and CAD block provide accurate pendant geometry for ceiling layout and spatial coordination. The 3D model and Revit family support BIM-compliant project documentation; the IFC file enables coordinated project delivery. A versatile and well-considered specification for residential, hospitality and commercial interior projects requiring a pendant of proven geometric design character.

Available as a 2D DWG drawing, 3D model, Revit file and IFC file.
