My wife and I decided to purchase headlamps after a couple of camping trips and doing without. We bought two different brands, not knowing which would be best, but by far this is the better. This lamp has an incredible 'high beam' that is a true spot light and several settings for different lighting needs. We do a lot of hiking and now that it is winter do a lot of night hiking and having this incredibly bright lamp makes the experience even more fun. Not sure what brand others are using but this lamp by far is the brightest that I have seen. I have logged several hours (5 or 6 hrs) already and there is no indication that the batteries are running low (still getting the green batteries are fully charged light on). The lamp is light weight and adjusts to different headgear easily. I have also hiked with it in the rain and have had no problems. Excellent light.
