    The constant increase in egg production year after year creates opportunities for new technologies. In this way, the lighting programs have been renewed, with different colors, in order to increase the production and quality of the eggs. The objective of this research is to evaluate the effect of the red LED lamp compared to the white LED lamp on the production of commercial laying hens with more than 70 weeks of life. 1920 commercial laying hens of the Lohmann LSL lineage with 70 weeks of age were used. The light sources used were: Red LED, White LED. The variables egg weight, production percentage, feed intake (g/bird/day), feed conversion (kg/kg), feed conversion (kg/dz), albumen height, Haugh unit, yolk color, peel strength, percentage of peel, thickness of peel. The birds received a continuous lighting program of 16 hours per day. A completely randomized design was adopted, with 480 birds per repetition, totaling 2 treatments and 8 repetitions. The variables were initially submitted to the Shapiro-Wilk test to verify whether or not the data have a normal distribution. Variables with normal distribution are presented as arithmetic mean and standard deviation. For comparison between treatments, the T test for independent samples was used. Productive and egg quality indices did not suffer any influences (p > 0.05) between the evaluated lamp colors. It is concluded that the color of the white or red LED lamp has no influence on the performance characteristics and egg quality of commercial laying hens with more than 70 weeks of life.
