It all depends. If you already know where everything is... smile

Actually, I tend to use my headlamp rather than a smaller light for those midnight calls. It's not so much that I need to see to go, it's that I need to see to get there. The small light, pointed at the ground, works fine for my footing. It's my heading that's the problem: little twigs and brush at eye level don't become apparent until I walk into them. I've gotten some nasty scratches that way, so I now opt for more light. I do tend to put my hand over it when I'm near other people's tents, though.
