Flashlight Collection Organization

So, for those fellow collectors out there, how do you organize your flashlights? By color, brand, size, power, or something else? Do you keep them in a glass case, drawer, protective case, or other?
I just picked up 2 of the red cases shown the photo. I've got a few other smaller cases and some extra pick and pluck inserts. I'm probably going to do all of the soda can and larger lights together, then the rest of my favorites in the other, but I'm not entirely sure.

What do you all do? Is there a functional advantage, or just satisfying the organization bug? Just curious 🤔.
