The article is devoted to the study of the influence of different modes of LED lamps color temperature in high-speed lighting conditions 2C:5T:3C:2T:3C:9T on productivity and viability, quality of the cross "Shaver" hens’ eggs. 4 modes of color temperature of radiation were tested: in the 1st group-in all periods of light 3000 K; in the 2nd group-the first and last periods of light 3000 K, the average period of light 5000 K; in the 3rd group-the first and last periods of light 5000 K, the average period of light 3000 K; group 4-the first half of each period of light 3000 K, the second half 5000 K. It was found that in groups 1, 2, 3 and 4 with high bird safety (99-100%), egg production per 1 laying hen was 148.6, 141.8, 155.5 and 140.5 pieces; egg weight-61.2, 60.9, 62.3 and 60.9 g; egg weight yield per 1 laying hen-8.99, 8.55, 9.56 and 8.47 kg; feed consumption per 1 kg of egg weight-3.31, 2.43, 2.24 and 2.40 kg. According to the complex of zootechnical indicators, the 3rd group was recognized as the best, which also surpassed other groups in absolute and relative weight of the yolk (15.04 g and 24.35% vs. 14.16-15.04 g and 23.31-24.35%), absolute weight of protein (40.50 g vs. 38.98-39.88 g) and slightly inferior in absolute and relative weight of the shell (6.73 g and 10.78% vs. 6.83-6.92 g and 11.08-11.39%).
