Spherical Petto pendant lamp: a modern eye-catcher over the table The the opening on the underneath side of the circular shade of the Petto pendant lamp is reminiscent of a stylised eye, which subtly emphasises its trend awareness. The lamp is fitted with a halogen bulb, the bright, direct light shines downwards & can, for example, brightly illuminate a table. With a diameter of just 15 cm, using more than one Petto is also a decorative lighting solution.
