Produced by Castaldi Lighting and signed by Alfonso Femia, the Bubble Up is the Bubble’s perfect shape replicated in the built-in version for false ceilings or partition walls. Circles of light that chase each other on the surfaces, they draw them transforming them in abstract artworks. Available in three diameters, 300-600-1000mm, Bubble Up offers to the designer the widest choice of composition and an instrument able to imprint a strong personality into the spaces. While the sign is strong the light instead is soft, evenly diffused by the screens in opal polycarbonate.
