It actually depends on how good your night vision is.
Check out how well you'll be able to see on a moonlit night in an open field without artificial light.
If you have a good night vision: Keep the light low & floody, with a brighter thrower handy in case you need to check something out farther away.
My night vision is exellent, so I need very little light to go around safely. If I'd go hiking right now, my Fenix E05 would be my primary choice, with the TK41 as the second long distance light.
If your night vision is pretty bad, go as bright as your lights & batteries allow you.
That's why Richpalm always uses at least 300 lumens, I saw him mention several times in his posts his night vision is very poor.
As an example, I have a friend with very poor night vision.
When we go out together in wintertime on a moonlit night, I can see everything clearly in open fields and such, and even see a touch of color, while my friend is almost blind.
He can only spot bright things a few feet away, without being able to tell if it's a piece of paper, or a light colored rock.
