I have an MT2A Pro, and have just ordered a HA11. Rechargeable lights are handy at home when the power is on, or you have a solar panel or other means to charge them up. But having AA battery lights and other gadgets, plus a pile of Energizer AA lithiums is the way to go for me.
MT20A and HA11 have been very good to me. I even had to get HA11's for some family members. They get the job done, even if you own 21700 lights. Very portable and lightweight for backup lights.
And can someone explain using the example of Fenix E12v2 and E20v2, which are powered by AA batteries. E12v2 glows for about an hour with a power of 160lm. But E20v2 shines for over 5 hours with a power of 150lm. Yes, this is real data - I have both. It seems that in practice, a single AA flashlight is not a waste of energy. Apparently, increasing the voltage causes large energy losses. Unless something else has an influence.
I own the Fenix E20 V2 and it's amazing how much run time it has in the low and medium modes and its also the most compact 2AA on the market. I have a few other 2AA flashlights and they dont have such efficiency. The LED is an SST20 I believe which is a really efficient LED, they must have made a really efficient driver for it. One thing to note is that when you draw the same current from two different battery sizes it's not the same power consumption. A larger battery will last exponentially longer not creating as much heat loss in electronic resistance. Low modes in a flashlight will always be much more efficient and sustain output closest to the ANSI FL1 rating. Most modes if not regulated will start to sag the battery voltage over a short time causing the flashlight to slowly dim. I've done many rundown tests and this is always the case unless you have a constant current driver like in the new Wurkkos FC11C.
I have 3 AA powered: Olight i5tEOS, Fenit WT20R and Fenix HP16R. For some reason, all the fishermen i know want 3xAAA, no 2xAA headlamps. I guess they are cheap and willing to pay only 10 euros for the flashlight.... My 4xAA Fenix HP16R is a monster. Its not lightweight but its comfortable enough, with a huge throw for a headlamp. And 4xAA or ni-mh will last forever in low level flood. I owned an AA Nitecore headlamp but the ratcheting system never lighted where i needed, it was too low or too high. It needed more little steps.
I love flashlights that take a single AA battery and 14500s lith ion
I use Eneloop rechargeable AA with a Maha charger/conditioner. 😮

Yeah I agree. AA is the best choice. I tend to prefer the diameter for pocket carry over an 18650 flashlight.

Theoretically, the E12v2 should be half as bright on one battery as the E20 on two. However, this is not to the detriment of e12v2.
