Headlamps

For early starts and general use, 200–350 lumens is plenty. If you’re navigating glaciers or mixed terrain, 400+ lumens helps cut glare and illuminate texture. Adjustable brightness lets you stretch battery life without losing visibility.

Rechargeables save waste and money over time but need reliable power access. Disposable batteries are great for long expeditions or cold environments where charging isn’t practical. Many climbers carry one of each for backup.

Cold kills batteries fast. Use lithium cells, keep spares in your jacket pocket, and avoid storing your lamp on your helmet overnight. A little prevention goes a long way toward avoiding a dark descent.
