I needed a head lamp for a recent camping expedition in conjunction with climbing Mt Kilimanjaro. This lamp was the perfect item! I used it in the tent at night (and on late night/early morning 'long drop' visits). Additionally, I had it on for 6 hours from midnight to dawn climbing for the summit. No issues whatsoever! It's lightweight with great adjust-ability for the beam angle. I'd recommend to anyone who needs something like this for camping or climbing. I'm looking forward to using it for early morning runs this spring.
