A quick chime-in on a rather old post.

I did a LOT of winter hiking last year, and plan to do it again this year. One thing I did learn as the group I hike with enjoys night hikes. Carry lights powered by lithium batteries. The end

Seriously, we would see non-lithium powered lights die below 30 degrees. Lithium lights would keep going strong without a problem.

Below 10 degrees, you want to go with LED lights (Luxeon preferably, they put out more light). Xenon lamps below that temperature (and espescially below 0) start fading slowly after exposure. They still output light, but it gets dicey.

Really, though, I hiked in temperatures down to -10 (although I don't recommend it) with my trusty Streamlight Argo HP headlamp, and it never failed me. There were several times that it was literally frozen - like the outside of it had ice on it - and it was still outputting stupid amounts of light.

Good luck!
