Nitecore NU33 Headlamp

The Nitecore NU33 is a rechargeable headlamp weighing 95.5 g, built around a 2000 mAh internal battery charged via USB rather than swappable cells. The main beam reaches 700 lumens with a 135 m throw, enough to light up a trail well ahead at night, while a separate flood setting spreads light for close-range camp tasks and a red light mode preserves night vision or avoids disturbing others in a shared tent. Run time stretches up to 147 hours at lower brightness settings, so a single charge can cover a multi-day trip if you dial the brightness down for most of the walking and save full power for technical sections. A lock mode stops it turning on by accident in a pack. Because the battery is built in rather than swappable, it suits trips where you can recharge every few days from a power bank or hut socket; for expeditions with no charging access, a headlamp on standard AA or AAA cells is the safer choice.
