Clear lines in the Abacus LED pendant luminaire made of mouth-blown glass The Terzani company is deeply influenced by Italian craftsmanship, which is reflected in every lamp. They combine the traditional processing of materials with a modern interpretation of light and lighting concepts. The Abacus LED pendant lamp is also made of traditional hand-blown opal glass. The handwork makes each lamp unique. The Abacus luminaire is inspired by slide rules, whose clear design stands for purity and functionality. This luminaire is characterised by straight lines and a straightforward design. The white glass spheres are attached to three individual suspensions, which are mounted at different heights. The tidy design integrates easily into a modern environment.
