> Check out Apollohealth.com. The research they cite points to wavelength, not intensity, as most beneficial for mood. High intensity is higher risk for macular degeneration. The site also has a free circadian rhythm test. I use the M2 light twice a day for 20 to 30 minutes, at 6:30am and 7:30pm. It works for me. Don't buy the box from them, though. I found it elsewhere on line for $90 less.

That does explain the misconception about lux (light intensity) being the important criterion, though. The only lamps capable of producing high lux were also high in blue output.
Thanks for bringing this to the table, Hugo.
