A big consideration is how well your eyes are adaptd to thee darkness. Way back when we hiked routinely at night using carbid lamps, usually on a low fuel setting in order to achieve longer run times. i doubt they gave more than 50 lumens.

Nowadays I have a great headlamp which can emit 1000 lumens. I almost always run it at a lower setting but it is nice to have the brighter capability.
