To keep the magic of the night but also to not impact the day view of the park, the challenge was also to hide the installation. We solved this constraint by gathering the maximum of luminaires with only two masts, located very carefully to reach all our targets with RGB LED flood lights and gobo projectors. The rest of the luminaires have been adapted and integrated in the architecture and landscape almost unit by unit, with an intense period of mock-up and tests on site. We experimented the integration of LED strip light in concrete mesh tubes to illuminate the 180 m of stairs of fibre optics in concrete rocks ceilings, of flood lights U.V. in real trees and of the bulky gobo projectors in a decorative fake tree. The client told us that she was really satisfied to have finally found a lighting designer that can deeply be involved and understand the specificity of her wishes, far from the standard lighting solutions that she has been tested in the past.
