1 - Circadian sensitivity (Melanopsin cells).
2 - Scotopic sensitivity (Rhodopsin cells) peaks at 507 nm.
3 - Photopic curve (Photopsin cells) peaking around 555nm.
4 - 6000K phosphor-based InGaN LED.

I made this diagram to illustrate why there is a concern about the blue LED component. For curve #4, I put the blue LED peak at ~450 nm. I placed #1 peak at ~460nm but now I believe the peak could be a bit more to the right at about ~470 nm.
