Hello,
I'm looking into buying a nice flashlight. This one peaked my interest:
SureFire 6P

I won't be getting it from REI though because I found it on-sale for $62 on SureFire's website. Anyway, this flashlight looks really great. In the reviews the people recommended getting one of the filters that SureFire offers because the beam will kill close-range night vision.

Here are two filters I'm debating between:
Red Filter

White

Does anyone have experience with filters? In the description of the filters the red is used to improve night vision and animals can't see it very well because of the red. I'm wondering if the white does the same thing only, the light comes out white. If that is the only difference between them I will get the white, but if the red improves night vision significantly over the white I will get that one. If anyone could shed some light, that would be great!
