New to forum and new to entrainment, (my Kasina is being delivered today), but had a question regarding the conclusions from this paper and their application to the LEDs used in the regular goggles or ganzframes. Does anyone know what the emission peak from the LEDs are? Forgive my ignorance if there is an obvious answer. I did already try to search the forum for the answer. Thanks in advance.

Tosini, et. al, Effects of blue light on the circadian system and eye physiology, Mol Vis. 2016; 22: 61-72.
"Thus, LEDs with an emission peak of around 470-480 nm should be preferred to LEDs that have an emission peak below 450 nm. Although we are convinced that exposure to blue light from LEDs in the range 470-480 nm for a short to medium period (days to a few weeks) should not significantly increase the risk of development of ocular pathologies, this conclusion cannot be generalized to a long-term exposure (months to years)."
