I keep running into alternative theories and facts about what specification of light to use in sun lamps for light therapy treatment.
Many actual afflicted people seem to just swear by just pumping as much light as humanly possible onto a person's eyes. I am talking up to thousands of watts, commercial LED flood lights. Other articles seem to place more importance on the color, and sometimes even on the exact frequency graph. And all consumer products seem to be small tablets you place about 6 inches from your face.
What, according to research, is the best setup for treating SAD? Is there an optimal color and intensity or is it just about increasing light available?
