Development of technical lighting capabilities maked it possible for lighting designers to implement any ideas. Although the structure of the human eye as a biological receiver of radiation is still the same despite lighting equipment progression. Many urban lighting design solutions implemented in various cities all over the world leads to promptly considering the issue of lighting quality assessment. A comprehensive study of an urban environment supported by town planning analysis allows to draw conclusions about the rationality of expended energy resources and the quality of realized objects. The relevance of luminance distribution analysis in a night city environment increases every year, especially for cities with lighting strategies aimed at a quantitative increasing of illuminated objects without hierarchy of priorities. By the example of the central part of Tula city an integrated approach to the analysis of evening image of the city has been considered, the luminance ratios were estimated for the facades located on 11 central city streets. This quantitative luminance levels analysis allows to draw objectively conclusions about the quality of existing light environment of the city and to understand possible steps for its further development in a new way.
