In this paper we are focusing on analysis of spectral power distribution (SPD) LED's lamp impact on botanical light pollution, described in relation to full moon light. We introduced new index RMPI which is called Photosynthesis Index in Relation to Moon. We found that in the case when lighting are realized by using LED luminaires instead of high pressure sodium (HPS) or metal halide (MH) lamps, light influence on plant vegetation process amplifies. Additionally our research shows that lamp's CCT is not a sufficient indicator of botanical light pollution and only SPD should be used for this purpose.
