title: The effect of high pressure sodium vapor lamps on the rat.
abstract: The effect of high pressure sodium vapor lamps and daylight-simulating fluorescent lights on the growth, hematology, and behavior of Sprague-Dawley rats has been investigated. Rats weaned under the sodium vapor lamps had slightly heavier adrenals than those exposed to the daylight lamps when the two lighting systems were equalized either for total irradiance or for scotopic illuminance. However, no differences were observed in the tail-flick response, hot plate response, or swimming endurance of rats housed under the two lighting conditions. No consistent differences were seen in the hemoglobin, red and white cell count, hematocrit, and mean cell volume between rats weaned under the high pressure sodium vapor lamps and daylight-simulating fluorescent lights.
