Even bettervthan expected since the 14500 battery included was at a full 1000 mAh, an improvement over the 920 mAh battery privided the past several years.
I also have the Tool AA 2.0 and the 3.0 has much improved runtime at the medium level of 130 lumens, which is what I use the most.
And not least: the lamp head uses the same thread as the Lumintop EDC15, so I can now have a very short Tool AA 3.0 head on an EDC15 body/battery container, with a twisty user interface. Perfect to live deep in my everyday pants.
Great improvement, Lumintop.
