Do AA flashlights last much less on full charge than 18650 flashlights? Say 4xAA versu 4x18650? my flashlight on 4x18650 could only last about 40 min on high, and maybe just twice on low, so although I hope to get an AA flashlight (more common battery, and less weight), I'm concerned about how long it will last on a full charge.
