Like the title says, I’m looking for an upgrade to my AAA keychain light, and I’m thinking of a CR123A flashlight, a bright and compact one, with mainly flood. However, I have a cheap chinese 18650 flashlight right now, so I was hoping to find a flashlight that can extend to run on my current 18650s, and then take a CR123A for when I wanted to pocket the light. Does such a light exist? (Hopefully cheapish)
