The municipality of Saldes, located at the base of the Pedraforca mountain, has a privileged location surrounded by mountains that protect it from light pollution from more populated areas such as La Cerdanya, Berga, Manresa or the metropolitan area of Barcelona. Thanks to the new 190/2015 Decree of environmental lighting management to protect the night environment of the Generalitat de Catalunya, Saldes wants to be defined as a reference area of light pollution and give value to the dark conditions that characterize it to turn into an astronomical reference that attracts more tourists.
In order to become the first reference area for the protection of night environment, the municipality has proposed replacing all street lighting for a more efficient one that minimizes sky glow. For this project, Salvi has proposed its blue wavelength filtering solution for LED lights, which are those that have more impact on light pollution. Therefore thanks to the Salvi Amber Diffuser, it is possible that energy efficiency does not adversely affect light pollution allowing the use of the best available technologies in protected environments.
