Connecting cities with light

Since 2002, LUCI is the international network of cities on urban lighting. We bring together local authorities worldwide that sustainably use light as a tool for social, cultural and economic development.

Cities are joined by associated members from the urban lighting ecosystem including the lighting industry, design agencies, light artists and light festival organisers, research institutes and more.
