The studies took place in 2001-03. The analysis involved 480 standard chinchilla. In chinchilla sheds, 12-hour light regime was applied: average illumination was 5 W/square m, while intensity was 0-90 lx. In 2001, at a selected part of the shed, new lamps were installed, which were of higher power, i.e. 10 W/square m, with 91-270 lx intensity. The whelping interval decreased with an increase in light intensity. The highest number of litter and total offspring from female per year were obtained under the higher range of light intensity. The range of light intensity between 150 and 240 lx was the most optimal
