Illumination of the Historic Centre in the Case of Tarnów, Poland, as a Source of Light Pollution
This study comprehensively assesses light pollution in Tarnów's historic Old Town, identifying key sources such as decorative and globe-type fixtures with high Sky Glow Contribution Index (SGCI) values (up to 0.62). Measurements revealed significant inconsistencies, with some areas under-lit (<1 lx) and others over-illuminated (>100 lx) on façades, far exceeding recommended thresholds. Only suspended street luminaires met CIE standards. The analysis projects 50-67% energy savings and substantial CO2 reductions through modernization with full cut-off LED luminaires and intelligent control systems. This provides a transferable model for sustainable lighting in heritage cities, balancing environmental protection, energy efficiency, and cultural preservation.

Uncontrolled Upward Light Emission
100% ULORPavement uplights and milky globe fixtures were found to contribute most significantly to skyglow, with ULOR values reaching 100% and 45.82% respectively, far exceeding the 15% limit for urban areas (E4 zone). This highlights a critical need for 'full cut-off' solutions to minimize environmental impact.

Tarnów's Heritage Lighting Dilemma
Tarnów's historic Old Town, a representative medium-sized city in Central Europe, faces a unique challenge in balancing heritage illumination with environmental protection. The study confirms that traditional lighting, while preserving architectural character, significantly contributes to light pollution and energy inefficiency. Modernization must sensitively integrate advanced LED technologies and intelligent controls without compromising the city's unique cultural identity.
