Here are all of the ones I'm aware of:
1. PT attitude
2. Streamlight Septor (headlamp)
3. 3-LED "cliplamp"- Streamlight and others
4. Dorcy 1-watt
5. PT Aurora (headlamp)
6. Arc AAA/Peak LED and the many "knockoffs"
7. Dorcy AAA
8. CMG/Gerber Sonic
9. EBay 21-LED light
Two ideas for finding more:
1. go to the LEDMUSEUM sight, where at the menu on the left side, Craig has grouped his light reviews by battery type
2. do a Google search; go to the advanced search page, type in AAA on the first line, and where it days exact phrase, type in LED flashlight. I did thid and came up with A LOT of choices, some "no-name" lights at pretty reasonable prices showed up on this search
