Does any flashlight use A23 cells?

Does any flashlight use A23 Energizer type cells? I am new to flashlights so forgive me if this is a dumb question. I thought I saw somewhere on youtube where a guy was putting TWO batteries in his LOD Fenix, but don't remember if they were this size or not, or if there was any advantage to doing so over a "normal" AAA type battery.

He was using a couple of half size NiMH AAA batteries (1/2AAA). This configuration is not recommended, but the L0D seems to cope well and output nearly doubles.

The original Glo-Toob uses this battery. It is a 12V, but not capable of delivering much current. Not suitable for most flashlights. Usable for marker lights or low output devices.
