Primary Fluorescents – Cast Edition is a minimal light series created by Eindhoven-based designers OS ∆ OOS. Aluminum was chosen as the final material for a number of reasons. A lost wax casting method made extremely precise copies of the prototype foam molds and retained all the detail of the original material. Aluminum – the way it is used in these new lights – also shares with the foam that it replicates the look of stone or concrete. It has the same size to weight ratio as marble, which pays homage to the initial prototypes.
