I can't believe how much light you can get out of such a tiny weightless package. I was wearing it in the tent and the person I was with did not need a light of his own. The same can probably be said for all LED headlamps but the unique strap on this one makes it extremely compact for when it's not on your head. As well, you can easily attach it to your pack's shoulder straps for immediately accessible light at all times. Great purchase!!!
