In broiler production systems the use of lighting programs proper is a factor that directly influences the welfare and birds productivity. The objective of this study was to evaluate two artificial lighting systems used in broiler poultry house, as to its allocative efficiency of luminance. The study was conducted in Iporã Pr. Evaluated the lighting of two aviaries with different lighting and building systems. One barn was closure with conventional system of black raffia bag (dark house), not being thermally insulated (N.ISO) and its lighting system consisted of incandescent bulbs, compact fluorescent and LED. The other barn was with extruded polystyrene panel (XPS), and thermally insulated (ISO) and its lighting system was composed entirely of compact fluorescent lamps. Was analyzed the extent of influence of external natural Sunshine, inside the poultry through the exhausts, and the degree of distribution of illumination in the poultry with statistical analysis and study of the distribution uniformity coefficient (CUD). Contour maps were produced showing the degree of internal luminance distribution for each set of lamp technology, in the area that did not suffer interference of external natural Sunshine. The results showed that the external natural Sunshine influenced the indoor lighting to distance of the second pillar (18m) from the bottom to the front and there was a better luminance uniformity in ISO aviary.
