... Curious, Why not Blue? because it's opposite of red and therefore more prone to mess with your dark-adjusted vision?
It absolutely destroys your night vision -especially blue LED. With red you can leave the lighted area and travel into black with almost no adjustment time needed, and your peripheral view of dark areas still works when in the red lit space.
Of course within reason, 100's of watts of blinding red LED will wipe out vision too, but not as badly as with the equivalent power of blue.
I'm thinking that blue light for our eyes is the same as 1k to 5k for our ears!
Since they invented blue LED's, everybody in theater seems to think that is now the best backstage, but the last show I was on the blue LED rope light they chose to use on the back of the set was just awful -hard to describe but it actually kinda "hurt" to look at in that pitch black space.
-Of course nobody wanted to listen to the sound guy, what does he know of lighting?
