#Preach_Eneloops
Only AA / AAA alkalines I have are cells I have forgotten about, and thus not yet replaced with Eneloop / Eneloop Pro's.
Considering the topic creator seems lost in the nethers and not seen since May, suggesting a 2AA is probably a moot point.
Something like a Sofirn SF15, Wurkkos WK05 or to stay with the single cell form factor, a Manker E02H or E03H.
Though I have always sworn by a bigger light (18650) for emergencies, to ensure there is power on the thing when needed.
It must have a simple UI or preferably 2 buttons for on / off and mode switching, no mode memory or parasitic drain, has an Eco / Moonlight-mode and takes multiple types of cells, including alkalines as a last resort.
I wish I had bought more ThruNite Neutron 2C V3's while I could. It didn't care what you fed it with.
