Strange things happened in Burnett Park Zoo in Syracuse, N.Y., when sunlight-simulating lights were installed in an effort to stop vandalism. The following article first appeared in The Los Angeles Times paper in February 17, 1980. At a speed of 186,000 miles a second from a source 93 million miles away rates with food, water and air support system on earth. It is light from the sun. But light also comes from manmade sources, and therein lies the problem.
Artificial light can make students irritable in school, and reduce production among factory workers.
That kind of light can interfere with calcium absorption in the elderly and contribute to brittle bones, scientific studies show. Incandescent bulbs and most fluorescent bulbs do not produce full-spectrum light. The science of photobiology is a recent one. Some photo biologists say doctors showed little interest in the subject until about five years ago. The American Society of Photo biology was founded only eight years ago.
