The HA29 UHE uses a 2,500mAh battery rated to -40°C. For context, Petzl says their batteries start degrading at -5°C. Black Diamond rates theirs to -17°C.
The HA29 holds roughly 75% capacity at temperatures where most headlamps are already dead.
1,200 lumens. 112g. Three colour temperatures so fog doesn't turn your beam into a white wall. IPX8 submersible (the entire Petzl lineup is IPX4 splash-resistant).
Takes 3x AAA as backup from any village shop on the trail.
The math: a guided Annapurna or Kinabalu trek runs $1,200-$2,000 SGD. T
he summit night is the whole reason you went. The HA29 UHE is $119, and it was actually tested for where you're going.
