About five or six years ago, I bought an LED flashlight that ran on one CR123 cell. It had a deeply crenelated bezel, was flat black, had a square beam (perhaps dedomed?), and I think it came out of a smaller shop in California. I remember it costing a couple hundred dollars. I wish I never sold it, but now I can't figure out what it was. Do you have any ideas what this mystery flashlight was?
