I’ve been using the biolite 800 pro for night touring. Works great, plenty of light for night skiing, especially in the 30 second burst mode. Fits great over a helmet.
keep in mind when you’re looking at headlamps for night touring that run time is less important than you’d think. Most nights there’s enough ambient light to walk uphill with the headlamp on an extremely low setting or completely off. Youll only need to run it at the highest setting when you’re actually skiing downhill.
also be aware that headlamps are useless if it’s nuking out.. a super bright headlight will illuminate all of the snow a few feet in front of your face and make it impossible to see where you’re going. Similar effect to when they hit hyperspace in the millennium falcon lol
