Thanks for the +1 Ethan.
I stopped looking at anything other than the 3AAA-18650 combo flashlights after my first one!
I should have added that I have seen 18650 batteries with individual capacities of 1800, 2200, 2400, 2600 mAh.
I got the 2600 mAh -- boy, do these suckers last!
Now, I see 3600 mAh versions are on the market.
