On spring 1999, the joint working group of the Italian Astronomical Society (SAIt) and UNI (Ente Normatore Italiano) components, after two years of long debate, settled a Technical Standard UNI10919 for the reduction of light pollution. This Standard limits the upward scattered luminous flux emitted by the lighting devices and defines the technical requirements of lighting installations to that purpose. This Standard regards light and lighting, is mandatory only for outdoor new lighting installations and for renewing the existing ones.
