Recommended Headlamps 

For XC Skiing, Hiking, Running

I've tried many, many, many headlamps over the years and none are as good as the new 3 Watt LED Headlamps. These new headlamps use a LUXEON LED - which is MUCH MUCH brighter than other LED headlamps.

I own the Princeton Tec Apex LED Headlamp. It is FABULOUS for cross country skiing, snowshoeing, running and hiking at night.  I would use this on my bike too if they had a way to mount it on your helmet, but they don't.  It's a little less bright than would be optimal for mountain biking.

The Petzl Myo XP LED Headlamp is another 3 Watt LED Headlamp which I suspect is also good, but I haven't tried it.

Don't bother wasting your money on cheaper headlamps!

For Mountain Biking

Coming Soon...  I'm trying to find a 5W Luxeon LED model that can be mounted on my handlebars or helmet.  I actually bought a tiny 5W Luxeon LED flashlight which I thought I could strap on my helmet, but the beam - although incredibly strong and bright, is very narrow so I can't recommend that yet.
