Petzl Swift RL

Petzl's trail-running and alpine lamp, and the one with Reactive Lighting: a sensor reads the scene and adjusts output on its own, which stretches the max-power runtime from a fixed two hours to anywhere between two and forty-five. Standard mode gives three plain levels and a six-second 1200-lumen boost, reaching 168 metres. The 2250 mAh pack is removable and charges by USB-C in five hours. It is IPX4, not submersible, and unlike the CORE models there is no AAA fallback.
