FYI, the picture of the guy wearing the orange headlamp is actually of the BD Ion (not one of the ones for sale in this drop). Incidentally, I have the newest version of the Ion and it is my favorite headlamp. Taking only 2 AAA batteries, it is about as lightweight as I can find (2 oz) and still function well enough for night hiking. The only thing I would change on it is a brighter red light (it's good for tasks in camp but too dim to hike with).
