Oh, this again.
Yes. Unequivocally. The only reason I wouldn't use white light is if I happened to have night vision on my head, so can see with that.
Here's another huge misconception from the Givens article:
"A much more accurate statement would be that 80% of pistol fights occur during the hours of darkness."
NO. Wrong. The original statement is correct because of doors, walls, and roofs. Lots of daytime low/no light shootings occur. Lots.
Otherwise, I totally disagree with the gist of his article. Flip his concept of context around: you are adequately lit so the bad guys can see you, but they are hiding in the shadows, etc. A classic technique from the dawn of time in fact. Ambient light is not consistent over the area, but varies. Also as some mentioned, adjusting to varying lighting conditions is a thing; if you go from bright sun into a room with comfortable lighting like a cozy restaurant, it is so relatively dark you are bumping into things. A white light is a good way to fix that.
I also have never, ever, ever understood the concern about pointing the gun at things to light them up. Just don't do that. The WML is for aiming. The handheld light you also have is for searching. Remember all the OODA loops and that stuff? Finding, identifying, aiming, and engaging are all different tasks so plan for them. Me, I wouldn't even have a gun out of the holster (or equivalent for home defense... low ready?) for most searching. Not a problem unless you make it one.
