ABSTRACT The spatial illuminance distribution interferes in the commercial production of eggs and electric energy consumption, being considered the second major source of costs in the production chain. Therefore, in this study the objective was to evaluate the spatial distribution of the illuminance level and electric energy consumption in two commercial aviaries for egg production. The first aviary was equipped with compact fluorescent lamps (CFL) and the second, with light-emitting diode (LED) lamps. The illuminances in the aviaries were analyzed using descriptive statistics and their spatial distribution through geostatistics. It was found that the aviary equipped with CFL showed better uniformity in the illuminances distribution and better results in...
