This is a great headlamp, the dual lenses are awesome. The lower lens is great in the tent when reading or just sitting around. The high light lens is great at night, for an LED it is great. The only draw back is that the battery life isn't great with the high light lens, I've been left without light twice because the batteries were dead.
