Tikka XP Rocks
I've owned a lot of headlamps, including Petzl, Princeton-tec, and BD, all of which have proven to be great. However, I think the best little lamp I've ever owned is the Tikka XP. When lying down in the tent to read, the absence of a battery pack in the back is appreciated. The ability to switch from spot to flood is awesome. Battery life is great too. Petzl is a great company and they got this one right.
