I received (3) of these several weeks ago and have been EDC'ing one of them ever since. My primary intent of the LF2X is for its ability to produce low level lighting. I keep this unit set at the lowest setting on P1 and something less than 50% (I'd estimate 20%-25%) on P2. For these tests, I used the default settings (P1 @ 15% and P2 @ 50%). None of these (3) lights arrived with any type of instructions or directions. I had to ask around on CPF and someone finally pointed me to a downloadable .PDF file. I must be honest, even with the instructions, I had one hell of a time programming this thing. With a bunch of help, I now know how to program P1 and P2 and how to reset the light to factory default. That's about all I'll ever need this light to do for my needs.
As others have already mentioned, the packaging was pretty nice, with a nice little supply of extras, including o-rings, split-ring, neck chain, pocket clip and key-chain connecting device. I love the pocket clip setup and have been using it from day one. The key-chain connecting device is a bit less impressive, mostly because it can (and will) come detached too easily. I've already mentioned the programming of this light was a mess for me. I know I'm not the sharpest knife in the drawer, but don't consider myself stupid either, but even after having the directions I was a bit confused. Now that I know how to set P1 and P2, I"m happy. That's the only thing I'll ever be configuring in this light. As with all my AAA and AA based lights, the Energizer E2 lithium (L92) is my preferred choice. I don't want or do I care for rechargeable cells, so the fact that the LF2X will run nicely on 10440's cells is pretty meaningless for me.
Here's the output of some of the testing that I've done so far. I've color-coded the legends so that each light has the same legend color in each for consistency. For example, Unit #1 is RED in each chart and even during multiple tests in a single chart. It better allows you to focus on a single light to see how it performs for each test.
This 1st chart shows how each of the (2) lights perform on the default P1 setting. P1 represents 15% output, per the folks at LiteFlux.
This 2nd chart shows how each of the (2) lights perform on the default P2 setting. P2 represents 50% output, per the folks at LiteFlux.
This 3rd chart is a blend of both charts, showing all the captured data up to this point. It should be easy to tell which plot in the chart represents alkaline vs. L92.
What really drew me into even getting the LF2X was its ability to produce low light. It's not the lowest I've even seen in a multi-level light, but it is for a 1 x AAA based light. Using that lowest level for dark-conditions is really nice for a variety of tasks. On P2, I'm set a bit brighter, but low enough where I have quite a bit of run-time available.
