I’m very happy with Panasonic eneloop AA Ni-MH rechargeable batteries in a Zebralignt H53Fw AA 4500k headlamp. I have night hiked quite a bit but that depends entirely on the terrain. Some places like canyon county is near impossible. I’ve used it for all manner of camp cooking and reading as it has a wide range of illumination settings. It is a tool used very often and highly useful around the house, looking into closets, drawers, the garage or under the sink. If mine were to break I’d get another just like it. It has a very smooth floody beam with a pleasant warm tint. They also come with a warmer tint yet or a cooler tint depending on one’s wants.
