I have an E11, myself; and it’s not a bad light, for something of that size. But - comparing apples with oranges doesn’t make sense. I don’t think there’s a Fenix light made that is compatible with 14500 batteries, or any other battery, for that matter, in that same form factor, that’s capable of that kind of output.
You know what they say about “the candle that burns twice as bright”… it’s certainly true here; but the output on this thing is tremendous, and is worth the sacrifice in reduced run time. The feature set is very impressive, as well.
Bottom line - the other poster doesn’t like the Nitecore brand. He happened to pick the smallest, most powerful light they make, but didn’t to take into consideration there are very few light companies mass producing a light of this power and form factor, anywhere close to this price range. I think it’s a positive step, for Nitecore, to offer such a light - and no, I’m not a Nitecore rep lol. I just happen to like their lights - enough to own nine of them, in various models/sizes/battery platforms.
Just out of curiosity @wolf359, what is it that you don’t like about Nitecore lights (aside from this particular model)?
