I've got a fenix p3d and a surefire U2 and their outputs are about the same, really.
The surefire has a better throw and wider corona.
The contest of ~60 dollar fenix versus 280 dollar surefire is a pretty clear victory for surefire.
The fenix is more carryable, except for its lack of a pocket clip.
I like the U2 more than the P3d, in general.
How much of a better throw do you find and how do the run times compare?
I guess I am wondering if there is enough of an improvement to justify the price difference.
