In line with the global recognition of light pollution, developed countries enact laws to control public lighting. The Republic of Croatia also acknowledges the importance of this issue and introduces legislative measures for protection against this type of pollution. The aim of this research is to examine the compliance of public lighting in Fužine with the regulations prescribed by the new law. Hypotheses are formulated regarding horizontal illumination, light intensity regulation, and the placement of lighting fixtures in accordance with regulations. Luxmeter, a device for measuring illumination, was employed to test these hypotheses during field research. Additionally, a rangefinder was used to measure precise distances between measurement stations. Other methods utilized in the field research include discussions, observations, and photodocumentation. Preceding all these, a method of collecting and studying data on light pollution and the functioning of the lighting system in the Fužine area was employed. The mapping of measurement points was conducted using the "OruxMap" application and processed in QGIS 3.24.3, while data analysis and synthesis were performed in MS Excel. Finally, an inductive-deductive method was used to summarize the entire research. This work contributes to understanding the issue of light pollution at the local level, evaluating the compliance of public lighting in Fužine with regulations, providing a basis for further measures to preserve the nocturnal environment and ecological balance.
