LUCI, the Lighting Urban Community International, is an international association of cities of light founded by Lyon in 2002. The association aims to create an atmospheric nighttime urban environment by using illumination and to share experiences between cities. Additionally, LUCI acts as an active discussion forum for its 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 the association in 2006 further strengthened Jyväskylä's position as the City of Light in Finland, and during the term of 2019–2020, Jyväskylä was the 1st Vice-Chair of the network board. In the upcoming 2020–2021 term Jyväskylä will serve as the President of the Network. International networking brings publicity to Jyväskylä and creates new opportunities for cooperation. The city aims to learn from the lighting solutions of other cities and gain a new perspective on developing its 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.
