Headlamps are essential tools for outdoor adventures. They allow us to see where we're going while keeping our hands free to do other things.
When shopping for a headlamp, you should consider how long it last. Some headlamps can run up to 2 hours on a single charge. Others only last 20 minutes.
A headlamp is better than a small flashlight for lighting up dark places such as caves, tunnels, or other areas where you cannot see well enough to find your way around. They are often carried in a pocket or clipped onto clothing, though some larger models can be worn like a hat. Some headlamps use batteries while others use rechargeable cells (also called "batteries"). Most headlamps come with two types of batteries: one for continuous flashing and another for steady light.
Rechargeable lights are usually smaller than non-rechargeable ones. This makes them easier to carry around, especially if they do not require any charging. In addition, rechargeable lights tend to last longer than their non-rechargeable counterparts, since they do not need to be recharged after every use. However, rechargeable lights can be more expensive than non-rechargeable.
