I used the recent Memorial Day sale to try out one of the new 4sevens smart lights, I went for the QS2L-X.
Here are some brief thoughts and a few pictures:
1) I was hoping to use a 16650 cell to run this light. Even though the spec clearly states 4v minimum, I was still hoping. Well, as others have discovered, the light pretty much shuts down with a 16650 cell. (I get moonlight and a flashing red low battery alert)
2) I was not expecting the unusual tailcap design. It requires more force to function than I prefer. The force required to activate the tailcap pretty much ruins all momentary modes for me. I do wish the tactical interface would latch on after short clicks, and just stay on momentarily for long clicks.
3) I use an android phone, and the app is not out yet for android. I stole my wife's phone long enough to try the app, but that ship has sailed and I'm stuck now in tactical mode... (see next item)
4) Pulling the batteries switches me back to the tactical UI. Doesn't matter how fast I do it, I'm always back to tactical. Is this because I'm no longer syncing with a phone? (I see there is away to switch the UI without a phone now, need to find that info again)
Those are some negatives, now to some positives:
5) The side switch is really nice. I like how it can be configured to stay lit 24/7.
6) There are several very low moonlight levels. Press and hold the side switch from off, and there are something like 3 moonlight modes.
7) The phone interface seems pretty good, I am looking forward to the android app...
8) Finally, there was almost no thread lock on my light. I was able to open it by hand, between the body and head and between the bezel and head.
Here's my light with a nichia 219C installed. (sorry for the dusty lens)
