Familiarity: I've used it several times
This lamp is a great answer to those looking to save weight! I use this around the campsite. It provides plenty of light for finishing up cooking, setting up the tent, and cleaning up. It is not for night hiking. Not bright enough. I have used it on one battery for approximately 8 hours. I'm not sure how much is left.
