Nitecore NU25 MCT UL Headlamp

For backpackers counting ounces. At 47 grams with its shock-cord headband, it weighs about half as much as most lamps here, yet still reaches 400 lumens and runs up to 45 hours at its lowest level. The built-in 700 mAh battery charges by USB-C and is the catch: it cannot be swapped, and its capacity is small, so on a multi-night trip you will be topping it up from a power bank. The red light has two brightness levels, so you can drop to the lower one for reading while a tentmate sleeps. IP66 handles a downpour. Choose it when weight matters more than a long run on high.
