For those dark nights spent in the tent, Garry has a Petzl Tikka headlamp which is suitable for proximity lighting and movement over short distances.
It has two lighting modes, mode one is for proximity work. Garry generally uses this when in the tent. Perhaps when cooking supper. Or when he wants an early start before sunrise and needs to pack his gear away.
Mode two is for movement and comes in very handy when Garry gets caught short in the night and needs to pay a visit to the bushes!
