Patera 900 Pendant by Louis Poulsen is the largest format in Øivind Slaatto's Fibonacci-derived pendant family — a 900mm diameter globe pendant that represents the Patera concept at full architectural scale. Slaatto's structural logic, derived from the logarithmic spiral of the nautilus shell and the mathematics of the Fibonacci sequence, places every oval opal aperture at a position and angle determined entirely by this geometric system. At 900mm the full complexity and density of the pattern is most legible, and the pendant becomes a genuinely monumental lighting object suited to the most significant interior ceiling positions.

The Patera 900 is appropriate for hotel atriums, restaurant main dining rooms, cultural institution spaces, large residential living areas with double-height volumes, and any interior context where a spherical pendant at architectural scale is central to the design concept. When lit, the 900 casts a rich, complex pattern of warm light through its many apertures across surrounding surfaces; the overall effect is atmospheric and enveloping rather than dramatic. Unlit, the pendant reads as a large, self-contained geometric object of considerable authority and scale.

For architects and interior designers, the Patera 900 DWG drawing and CAD block are essential for spatial planning and structural suspension coordination at this scale. The 3D model and Revit family support BIM documentation; the IFC file enables full structural and M&E coordination. The definitive specification resource for this landmark pendant in large-scale residential, hospitality and cultural interior projects.

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