True, but if you do the math you end up with more lumens from blue LEDs than from cyan.[/QUOTE]The information from that link is interesting in that it supports both positions.Other studies have found blue light to be dangerous.
**broken link removed**The ideal wavelength for scotopic vision is 498nm which is cyan. You can get 505nm cyan LEDs which is near enough the ideal wavelength.
I can understand causing retinal damage at the intensities they are doing the tests at. However, it also states that the iris is opened by a preponderance of blue light in the spectrum. That means that more light gets in allowing you to see at lower light levels, which reduces the power consumption and by extension the chances for retinal damage.
