you're climbing outdoors or camping at a climbing spot, chances are you will be
outside in the dark at some point. Whether it's early starts to get to crags,
or late finishes on challenging projects, a headlamp is an invaluable piece of
equipment. The latest headlamps have energy-efficient LEDs and are powered
either by disposable or rechargeable batteries. The lamps attach to an elastic
and adjustable strap that can be optimally fitted to the helmet so it doesn't
slip. The intensity and width of the beam can often also be adjusted.
