Flashlight Enthusiast
Since we're just talking EDC on your person, I'd rather carry more lights than spare batteries. Who wants to go fumbling around in the dark changing batteries when you could just pull out another flashlight?
Of course, you are right. I suppose I have in mind a specific set of circumstances involving an extended night hike, two flashlights, and spare batteries for both lights. As for EDC, I normally just carry my Elzetta Bravo with two spare primaries in a delrin capsule. However, I like to carry more firepower when I'm intentionally going into the dark.
