LUCI, the Lighting Urban Community International, is an international association of cities of light founded by Lyon in 2002. The aim of the association is to create an atmospheric nighttime urban environment by using illumination, and to share experience between cities. LUCI acts as an active discussion forum for members. The association is also responsible for promoting the importance of lighting globally as a tool for urban development and environmental planning.

Jyväskylä was the first Finnish city to join LUCI. Joining in 2006 further strengthened Jyväskylä's position as the City of Light in Finland, and during years 2019-2020, Jyväskylä will be the 1st Vice Chair of the network board. International networking brings Jyväskylä publicity and creates new opportunities for cooperation. The city aims to learn from the lighting solutions of other cities and gain new perspective on developing its own urban lighting.

In addition to Jyväskylä, the association includes more than 70 cities around the world, including Lyon, Gothenburg, Tartu, Glasgow and Shanghai. From Finland, Helsinki and Oulu have also joined LUCI. In addition to cities, members of the association include various partners, such as educational institutions and companies.
