Finally another man of culture.
I'd go a step further and recommend the Zebralight SC5c or SC5w. They are slightly thicker but they are designed to give 14500 output on a AA sized battery and still smaller than most. The SC5c would be my choice as it's a 4000K tint with a CRI of 93-95 but you're giving up some over lumens (476 max vs the 550) the UI is predictable, intuitive and the newer versions are entirely programmable so if you really just wanted to make a single mode light you could.

My other favorite AA light is the Eagletac D25A Mk2 as it's the slimmest AA light out there period that's still worth a damn and it has a pretty good UI with a good. I have one with the Nichia emitter which reduces the overall output but it has the nicest tint and CRI of the options. If you don't care about tint you can get 400 lumens out of a single AA

One of the best budget AA out there is the Thrunite T10 II as it's $24 but it's only pushing 160 lumens

If you're willing to go to Lithium Ion batteries you can get the Zebralight SC64c which isn't much bigger than the SC5 but it does put out 900 lumens and has the same UI and all that:

Or you can go crazy with this little pocket rocket the Lumintop FW3A that will out 2800 lumens out something not much thicker but it will get super hot and might burn you.

If 2800 lumens isn't enough you can step it up to the Emisar D4V2 which can put out 4200 lumens with a slightly thicker head. Be careful if you go this route though as the Emisar D4 on full power will get so hot it will burn through pants pockets, bags or anything else you have near it. It will light paper on fire and it will eventually get so hot that it will desolder the LED itself but don't worry as it will get way to hold to old before then.

If that isn't enough you you can even put a 18350 tube on it (compatible with a CR123a) and get the same output with a reduced runtime in a tiny little package like this:
