Running well on Eneloops is important for me, because I don’t have 10440 yet and I’m not sure yet if I will be able to order the Efest batteries.
According to a review on another forum the Thrunite Ti3 was measure to output a steady ~150 lumens on Eneloops for aroung 17 minutes which is good for what I expect from a small, relatively bright flashlight.
According to this (comparison of Tank E09 vs i3s on AAA) I think I actually prefer the tank’s beam profile as well as the fact that it is brighter…
But probably on 10440 both i3s and Ti3 will be equally bright, direct driving the LED?
