Comments about Princeton Tec Apex Extreme Headlamp:

The light I received from SunnySports.com was different then the one pictured as it had a band over the top of the head.
Used the light for a 6 hour night hike in the White Mountains of New Hampshire. The second lowest setting was sufficient for finding my way. At hour 3 the weather rolled in with 40-50mph winds/rain/hail and the light never moved or stopped working.
I clipped the battery pack to loop on the back of my fanny pack and it never came off. Even when I fell pretty hard on the pack after slipping on the wet rocks.
I look forward to using this light on early morning mountain bike rides and night time XC skiing trips this fall/winter.
