I frequently walk my dog late at night in the woods, it’s maybe a 1.5 mile circuit on a trail that I cut or spliced out of game trails. I find a decent headlamp that is on the weak/wide beam side to be most useful, and have used everything from 100-250-500-1000 lumens hand flashlights to light up the various critters of the night that I encounter. If it’s anywhere near a full moon I might not run a light at all, except the one clipped to the dog.
500 is more than adequate most of the time although I have recently used 500 + 1000 to light up a small herd of deer running right past us. You get some light splash back from the closer trees, this is the primary drawback of going with the more powerful lights while in the woods. This would be less of an issue in more open areas.
