This is so light and so small and great as either an emergency light, a light to use in the tent or around camp. It will help you see what you are doing. What it is not so good at is seeing where you are going. Range is not really far enough. I would suggest carry the extra 7 grams and get the much brighter and similarly small Petzl Bindi if you want to walk anywhere in the wilderness at night.

Ultralight weight emergency headlamp.
This an impressively light and very compact emergency headlamp. Great as a fall back light if you find yourself accidentally still out at dark after a day walk or as an emergency back up. At 50 lumens, it's not the brightest headlamp you will find but it's size and impressive 26 gram weight mean it will go unnoticed in your pack until you need it. Although I've not tested the endurance of its battery life it does seem to outdo its competitors with a suggested battery life of 10 hours. If you need an emergency back up light that won't break the scales then I can't recommend this highly enough.

Great ultralight headlamp
Very good light headlamp.This update gives more lumens,without adding weight.
The cordlock-whistle can be removed with some effort.
I put a lighter simple cordlock.The headband is narrow of course,and the batteries are not very common.
But it is probably the best option in terms of weight and size to brightness.
