Just a heads up for anyone looking for a headlamp for serious night hiking I can personally recommend the LED Lenser H7. LED Lenser is a German company that I only recently learned about.
I used this headlamp for night hiking on the Foothills Trail this week and it's the brightest headlamp I think I've ever seen.
This is it: http://www.zweibrueder.com/ENG/produ...e/h7.php?id=h7 and I picked it up off Amazon for $44.25. The package includes 3 lithium batteries and they recommend that you only use lithium batteries with the unit.
The package says 150 lumens but the website says 170 - all I know is that it lights up the trail like nothing I've ever seen. One of the neat things about it is that you can adjust the beam so that it projects light over a large area (more diffuse) or focused tightly on a small area (very bright).
Weight 4.0 oz exactly with 3 lithium batteries on my scale compared to 2.7 for my Petzel and 2.5 for my Princeton.
Definitely a keeper - I guess it could even be considered dual use gear because you could use it as a headlight on your car if you had to.
