Petzl Tikkina Headlamp

The inexpensive spare, usually around $20, and the lamp to hand a child or a guest who forgot theirs. One button, no menus to learn, and three AAA batteries that last for around 100 hours on the lowest setting. It is honest about what it is: no red mode, no lock and modest output, which is plenty for cooking, reading and the walk to the restroom but thin for night hiking. If you later want rechargeable power, it accepts Petzl's CORE pack, sold separately. IPX4 covers rain but not a drop in a creek.
