The amazing this about the E0 is it`s regulated for around 9 hours, The ARC AAA is not regulated and cost so much more.

I tried an discharge Eneloop AAA discharged to 0.9v in my Fenix E0 and it did not light-up at all, then i tried it in an Fenix LOP which lights up bright and my ARC-P that also light up bright, So it looks like an Fenix E0 is not the keychain light to have in an emergency.
