Slovenia is a country, which protects its natural heritage and puts real emphasis on ecology and minimalisation of light pollution. Recently we have visited our client in beautiful Bled, for whom we produce LED reflectors with customized light scattering. This kind of illumination has significant economic advantages and minimalizes light "smog", thereby ensuring the ecological aspect of its operation. Visiting Slovenia was also interesting for us to "check" the light advertisements, which are already for several years reliably illuminated with our LED modules in many shopping centers and retail chains, such as SPAR, INTERSPAR, HERVIS or DM.
