My favorite-ever headlamp was the Princeton Tec Scout. It tilted, and had a little lip that, when it wasn't in tilt position, covered the switch, neatly eliminating the chance that you would accidentally turn it on. Bright light, too.

Naturally, being a very good product, they quit making it.

I've used the e+Lite a few times as my primary light, but it's mostly been my back-up light, so I can see to change batteries. (For some reason, my batteries also seem to die at night, when it's dark.)
