I'm not aware of what lights out there that accommodate AA and AAA and will hold up at those depths. But if you are willing to use NiMH output should become much better. There is a driver available that can provide 800ma to the led off of a single NiMH cell (Keep in mind that it must draw 2000+ma from the battery to do this). It is now sold as Deal extreme SKU 7880, but it was once known as the RV7 driver. It was made buy a guy here on the forums, RV7. As far as I know it's probably the best driver available for 1xNiMH. It can also be modified for a single mode, I think I've got an old thread link somewhere.
I guess 14500 and would work as well with the right driver.
