Estadio is a family of luminaires that pays tribute to functionalist industrial architecture and public lighting, with glass block as its defining element. Widely used in Spain between the 1950s and 1980s—especially in public and communal buildings—this material offered an affordable solution during times of brick scarcity, while allowing natural light to pass through without compromising privacy—thanks to its translucent quality. Its modular repetition, sober geometry, and durability connect it to an urban and popular aesthetic rooted in efficiency and formal clarity.
