The Ferrante Aporti Offices project required a ceiling mounted lighting fixture for illuminating the lobby with diffuse light but without the necessary space in the ceiling, the common recessed light fittings was not an option. As a consequence, the surface mounted ceiling lamp, was decided to become a design feature, yet satisfying the necessary illuminance, and avoiding glare. The idea was to create a large uniformly luminous disc aligned to the scale of the space. After multiple tests and mockups, the Manufacturer provided specific high-power LEDs and custom made lenses. The final product satisfied the initial intentions with a significantly high performing ceiling lamp, yet assuring the visual comfort.
