    Surefireís legacy products the M500 and M900 had separate led navigation lights (I think the options were red or dim white). They were intended for low light navigation with appropriate muzzle discipline like El Cid referenced. The Aviator light also had a color LED option for when some close in work or minimal illumination was necessary without messing up oneís night vision. I have also read that red and green lighting is better for fine detail, but I also believe thatís true mostly at close distances, like reading a map or other ďadminĒ tasks, as opposed to across the room or down the alley distances.

    Predator hunters have used green light for years. The theory is that the green light is not as recognizable to many animals (coyotes and pigs?), while again, preserving the hunterís biological night vision and situational awareness. Itís not better light, in its purest sense, itís sufficient illumination for the task at hand while offering some ancillary benefits.

    For defensive purposes, white light has been king for a while. Reason being, white light is typically brighter, allowing the user to not only make out the subject, but distinguishing features, like facial features, clothing, objects in hand, etc. Predator hunters donít have to have that level of specificity in target identification, normally; they arenít looking to distinguish a pig from a pig with a gun itís hand, or a coyote from a different coyote with a goatee. If theyíre after a specific animal, like culling a nuisance predator, white light might be more appropriate.

    Back to defensive use. White light illuminates a possible subject better. It allows for better recognition of fine features at a little more distance, objects, etc., and may or may not provide an advantage by blinding the subject or offering a psychological advantage. White light also, in my experience, also provides better depth perception. The downside is that bright white light also degrades your own night vision. I tend to think that in most circumstances thatís an acceptable trade.

    One of the truisms of CQB is that the most dangerous room is the one that youíre in. In its most basic sense, you can consider a four walled room with you and the subject in there. There MIGHT be a dude waiting for you outside the spill range of the white light. I acknowledge that, but tactics and other factors have to mitigate that risk. I also extend the concept of the ďroomĒ to the cone of light originating at you and extending to and beyond (4th rule) the subject youíre illuminating. There IS someone in that room who you have to deal with first, before the hypotheticals. White light gives you the best illumination, and therefore the most information, so you can make the best decision in that moment.
    The advice above is worth exactly what you paid for it.

    I have a Streamlight Weapon light on my night hunting rifle. I use a reds lens cover on it. Between that and the navigation mode on the light. It barely lights up anything, and that's exactly what i want. I have to walk over a mile in pitch black, up a big incline. I used it just to get me back and forth. When i get to one of the stands, I flip the cover off and I get full lumens. Its the only weapon that gets a lens filter on it.
