The Theorem cylinder glass table lamp explores light and its propagation through a sculptural design. Featuring a luminous source housed within a wooden base, light reflects on a borosilicate sphere with dual finishes—glossy gold and milk white. The sphere can be manually rotated to alter the direction and diffusion of light beams. Topped with a laser-cut opaline PMMA diffuser, this piece combines innovative materials and craftsmanship for a dynamic lighting experience.
