The lights in the C-130 on our nighttime airborne missions in SE Asia
were deep red to preserve our night vision, the trip to the jump target
was in the dark. The effect of any light above the bottom end of the
visual spectrum on night vision is dramatic. I'm a monochromat, I don't
really know what "red" looks like to everyone else, and my dim light
vision was really good, but anything higher in the spectrum killed mine
just like all my troopers. The fact that I can adjust the LCD
brightness on my K3 is really cool, I normally run LCD at 2 or 3.
The one problem I have is I can't see the numbers on the keypad keys in
any light. Fortunately, I know what the keypad looks like. [:=)

Kinda reminds me of the red lights we used in the darkroom when developing
film back in the day...
