The project is the result of a competition proposed by Beliris, whose preliminary studies were carried out by B. Fondu (at the request of the King Baudouin Foundation) for Le Cinquantenaire, built in 1880 to mark the 50th anniversary of the Belgian Revolution.

A partnership between the urban planning office JP Majot, ACTLD and Vitech was established to develop the lighting plan for this historic site, equipping it with two lighting scenarios (evening and night) specifically designed for reasons of consumption, aesthetics and light pollution.

The old lighting, which dated from the 1970s, was obsolete and inefficient, consuming between 500 and 1,000 watts per lamp. They have been replaced by LED lighting, which reduces energy consumption by more than 50% and provides greater variety and precision in lighting.

The new lighting creates a subtle alternation of light and shadow, emphasizing the rhythm of this classical style monument, a play of color tones between the interior spaces and the facades, reinforcing the perception of depth and perspective, and adds very focused accents that beautifully highlight the copper sculptures. This new lighting generates a balanced, coherent and impressive visual impact for this major monument of the Brussels landscape.

LED Linear™ luminaires of the KALYPSO family were used for the inner vaults and the architraves (the beams that rest on the column capitals), thus highlighting the smaller details of Cinquantenaire.
