Lightweight and comfortable

Great, good beam. Prefer the band over just the cords, even with a smidgen of extra weight

Versatile and bright

My second time buying this light. First one found a spot on the nightstand for reading and late night trips to the restroom after it got left in the jacket pocket when it went through the washer and dryer. It suffered a slight crack in the housing and even though it works fine I was able to score another one from here when it was on sale. Great lamp, love the 2 button interface. Red light is a little bright inside the tent but good outside. The double click low light mode gets used almost every night for reading. Paired with the NB10000 is a great combination.

Great head lamp and excellent battery life!

I took this on a 9 night, 10 day excursion into Yellowstone at the beginning of October. I never charged the lamp during the trip. I used it for around an hour of use per day, some times more, sometimes less. Super comfortable, easy to use, and battery life for days! I high recommend this ultralight headlamp. It's the best I've ever had.
