Single AA and 14500 flashlights
AA flashlight have been around for quite some time, and will stay around for quite some time. But at the meantime, they are becoming less and less popular. The main reason for it being their output. Lumen addicts tend to neglect these flashlight. I for myself enjoy using single AA lights a lot!
A very, very popular light from back in the day. This is a review of the classic version of the Sunwayman V11R. The review includes the use of the extender in order to use it with an AA battery.
Lumintop ED15 is an older model with XM-L2 led, but still a nice EDC.
2/3/4* AA and 14500 flashlights
There are tons of multi AA flashlights that can be very useful for families and people who want to use powerful flashlight but are afraid of using lithium batteries. Lithium batteries powered flashlight will always be more powerful, but the multi AA lights can be a very good alternative.
