I too like the Petzl e+lite. The batteries can be exensive, but can be purchased in small bulk via the internet for a lot less, and these little lithium batteries have very good shelf life.

I throw away the hard shell protective case the light comes in, just store it sometimes in a snack sized ziplock so the headband doesn't tangle with other stuff.

Note the choice for winter or shoulder-season hiking or night hiking, but when the days are long and you mostly use your headlamp for puttering around in your tent at night --- perfect, IMO.
