Flextail TINY Helio 600Z

The Flextail TINY Helio 600Z is built around a swappable 900 mAh battery, which sets it apart from most ultralight headlamps with a fixed built-in cell — on a longer trip you can carry a spare battery and recharge the lamp without a power bank. At 60 g it sits in the lighter half of its class, while 600 lm output and 100 m beam distance are above average for that weight. Six modes are available, including separate spot and flood beams, a red mode that preserves night vision, and SOS blinking. The IPX7 rating (submersible to 1 m) indicates it can handle rain and accidental dunking, not just splashes. The claimed 50-hour runtime almost certainly applies to the lowest brightness setting; at full 600 lm output, battery life will drop sharply — a common trade-off in compact headlamps. It suits multi-day treks and regular camping trips where swapping a battery beats waiting around for a USB-C recharge.
