All good, but it uses those odd (here in Europe) CR123's. I am waiting for a cree headlamp which can take AAA or AA batteries - although I am very happy with my Petzl Tikka XP (the low setting is enough for the most time in woods), but my brother needs a headlamp too (and I don't want to buy something with Luxeons, when Cree is available) - I hope a Cree Petzl/Princeton headlamp will appear in the near future...
