ABSTRACT
Cluj-Napoca is an over 2000 years old city in North-Western Romania, rich of historical and architectural monuments. With its 500,000 inhabitants, it is the fifth largest city in our country. Since 1906 the lighting network of the city of Cluj has operated from the electric distribution system. At the end of 1950s, following the application of discharge lamps, the evolution became noteworthy. Unfortunately, before 1989, due to the extremely wrong policy of the former communist government, the theoretical required illumination levels were only a third of what was recommended by European standards; the real illumination levels were even worse. Today, a great deal of effort is made to refurbish the public lighting networks of the city. The paper presents the historical stages of public lighting in Cluj-Napoca, a proposed project for the enhancement of lighting system and the efforts related to its accomplishment. Measurements done proved good photometric and economical results; energy quality aspects of the electric network concerned with unbalanced and harmonic distortions on distribution system have to be managed in the future.
