Flashlight and Headlamp Round-Up: Burn Time

Whether you’re venturing through a covered cave, braving through a forest during the dead of night, or hiking through a canyon under the stars, when it comes to using a flashlight, the last thing you want is the battery dying, leaving you in the dark. This means you want a light source that will have the longest burn time as possible. 

Below are some of our favorite flashlights and headlamps with a very reliable burn time.

What is Burn time?

Burn time is how long a flashlight can operate without replacing or recharging the battery. This is usually measured by how long it takes for a flashlight to get noticeably dimmer.
