— Groups of seven timed pregnant rats were exposed to equal illuminances (75 ftcandles) from high‐pressure sodium vapor bulbs (202 μW/cm 2 ) or sunlight‐simulating fluorescent bulbs (309 μW/cm 2 ). Offspring raised under sodium light weighed more during early development and had larger adrenal glands at autopsy (days 26 or 28 for males; day 48 for females) than those raised under fluorescent light. These data provide further evidence that the spectral quality of artificial lighting is a major determinant of its effects on mammalian growth and development.
