I guess it's because of wavelenght or some physical theory I can't be arsed to research.

But basically red light doesn't "go very far", let's you see what's directly in front of you (1/22 metres tops) and because of that, people further away won't be able to see anything but the source itself (LED or light bulb). really useful for night games if you can't afford a £2k NVG set.

I use red lights when camping for when I still want to retain my mk1 eyeball "night vision sight" but at the same time be able to read a map or look what I'm stepping on.

So,

TL;DR

to be able to see and still remain somewhat stealthy

The best way to describe it is that the light "dies" a lot sooner than white light.

So a red torch will help you see the immediate area, but won't illuminate around the corner and down the corridor to tell potential enemies where you are.

Same thing with my green torch, but green is a bit brighter than red.

(I might be wrong!)

Cheers guys,  
looked cool in CPD, but sure they are using some surefire $500+ torch with infinite batteries!  :lol:

 

Red is also the colour that fades first underwater.

When I dive and go past 15/16 metres of depth all the red coloured thingies like corals and starfishes become grey-ish until i shine a torch on them.

Red light is used by the military as it doesnt affect your natural nightvision in the same way white light does.  It takes 45mins for your natural nightvision to adjust to the ambient light conditions.  

I've just bought a red torch because I didn't have a red torch.  Interesting to see that there's some science (or at least technobabble) behind it.

Apparently its called the Purkinje effect.
