I agree with Greg, the Tikka is great for most situations but not all. I had a heck of a time using it skiing last winter. I wouldn't suggest it. It got a bit dodgy. But for night hikes and camp use, you can't beat it. It doesn't hurt your head to have it on for long amounts of time, doesn't weigh you down to have it on your helmet either. I also found that the on/off switch wasn't easy to use with gloves and it does get a bit testy. Still a great lamp though!
