Pistoia regains a new identity thanks to the lighting redevelopment project carried out by Hera. The intervention selected Polis as a key element: a lighting fixture designed to blend elegantly and discreetly into the most delicate urban settings, replacing old systems with high-efficiency LED solutions. Its sober design - simple, flat, and circular in shape - naturally integrates into the urban fabric, enhancing public spaces and the surrounding environment without altering their historical identity. The project focuses on balancing aesthetics and performance: construction quality, LED technology, and attention to the context combine to create a more welcoming and safer urban environment, even at night.
