Overview
- The switch-on took place Sunday at 6:30 p.m. with patron Léa Seydoux in attendance and a performance by Charlotte Cardin.
- The display runs nightly through January 4, lighting up from 5 p.m. to midnight and until 1 a.m. on Fridays and Saturdays.
- About 400 trees are decorated with connected LED garlands that change color via an AI system.
- The production is credited to designer Thierry Reboul with lighting by Thomas Dechandon and technology from Blachère Illuminations.
- Organizers say the setup uses power comparable to two average French households per year, and the avenue was pedestrian-only for the ceremony with the next car-free day set for December 7.
