For walking at night a torch held low gives better definition than a headtorch. If I'm doing dark night micronav I'll always have a bright handheld spot for occasional use and a less bright headlamp, I find it more useful on rough ground.
But for most purposes a headtorch is more practical. Especially in camp. A piece of shockcord on a microlight is minimal weight.
Or a Petzl E-lite ( neither great for off trail walking though...)
