    Default Surefire Stratum (S2-BK-WH) Review

    I received my new Surefire S2-BK-WH from batteryjunction.com yesterday and thought I'd post my initial thoughts and, of course, photos. When I first opened the package, I immediately set the light beside my old 6P for comparison. It obviously looks and feels totally different, but I can already tell that the S2 could quickly become the new standard, dependable, go-to Surefire.

    5 > 50 >160 Lumen Output. You can 'bump' the tailswitch to cycle through or turn the light on/off within two seconds to cycle. The S2 always initiates on the low setting.




    Standard, sharp looking Surefire packaging.




    A00017. I'm not sure what I think of the "FC CE" stamp on the bezel. It seems a bit unnecessary.




    Switch:




    The bezel is designed with numerous small teeth that show up in the beam pattern. However, the spill on the S2 is incredibly broad, so the pattern doesn't show when using the light outside.




    The Stratum feels really nice in hand: well balanced, notched for grip, and built like a tank. It's mil-spec hard-anodized aluminum body feels smooth, heavy, and gives you that sense that most Surefire lights do: this thing is going to last forever (and if it doesn't, SF will stand behind it).

    The clicky switch stands out most on this light compared to my other SF's. The S2's switch is so well balanced in that it's easy to 'bump' through the three modes, but it's definitely resistant enough that it won't accidently bump or click on in pocket. Low: 5 lumens @ 75 hours / Medium: 50 lumens @ 15 hours / High: 160 lumens @ 2 hours.

    The beam pattern is definitely a big change after being so used to the TIR optic. The spill on this thing is ridiculous, and the spot is actually quite tight. I wouldn't call it a thrower by any stretch, but it's tighter than the pattern from my LX2 and E2DL, for sure. I was surprised the bezel felt quite warm after running the Stratum for about four to five minutes on High. By no means is it uncomfortable, but I expected it to take longer to reach that warmth level considering the extra aluminum on the S2 compared to the LX1 or E2DL.

    I hope this has given a little insight into this brand new light from Surefire. This is my first review, so feel free to drop any questions below and I'll try to answer. Thanks.

    BEAUTIFUL!

    Thanks for posting it.

    Can you see what kind of LED it has inside ?

    I have no clue how to get this over to the "reviews" thread, so feel free to weigh in here if you know.

    Nice review!

    Nice job on the low SN! Yeah, I agree the big FCC/CE could be placed smaller on the side, or not at all.

    Not a thrower, but tighter than the LX2? To me at least the LX2 is one of the tighest, farthest throwing lights I've seen. Anyway, I'm a big fan of lights with reflectors with a decent amount of spill, so this light looks great!

    I assume the head is one piece. Is it compatable / lego-able with any other SF lights?

    Would love to see some beamshots of this thing.

    The important thing: what do people think of what appears to be SF's new logo?

    Good thought about the LX2....it is a tight beam pattern and I would call it a thrower as well. The Stratum has an even tighter spot, but it has so much spill that the spot itself isn't near as hot/intense as the LX2. Does that make sense? I guess it's a thrower in the sense that the spot is tight, but my guess is the lux rating wouldn't be too impressive.

    The new logo...hmmm...I'm just noticing that. It's amazing how many detailed changes SF's made to the new line up.

    Yep, that's a K2. I would assume it's a K2 TFFC.

    Yes, the K2's have been discontinued.

    Was there a press release issued on this? I can not find it on their web site?

    I had all the Z2-S press info, but nothing on this.

    Yes! Thanks for that clarification. This light sounds (and looks) very cool. I may have to add it to my ever-expanding "to buy" list.

    I wish they found a better way to switch then by using this "cycle through the modes" nonsense that many other brands are already working past.

    I wish they would find a better way to let us know of these things.

    Still, it seems like a great light.

    Thanks for the post and review!

    Please tell us what the LED looks like. Is it hexagonal also?
    I wonder if they're using the K2's consistently across the line?

    Low, medium and high, nice black finish, reflector. I might have to buy one of these. This seems as if Surefire has actually made a light for me!

    Why is this light not on the Surefire website? Where can I buy one?

    So on high it is 2hrs and not 1hr? For some reason I was thinking this was 1hr, maybe I read that on some specs at a website.

    Runtime on high is 2hrs according to the owners manual, 160 lumens output on high.

    Trippy, i was going to lookup the Stratum model in CPF search but saw this thread. I saw it listed as a new product in knifecenter. I don't remember seeing this model mentioned before.

    Is the Stratum a new type of SF flashlight? Does it replace an existing model?

    Makes you wonder how many they have. The new Z2-S houses a K2 as well.

    Wow, Seems like an updated 6P doesnt it?

    I know SF must have an inventory of those K2 leds and intends on using them all up in their new product lineup but isnt the K2 from about 2 years ago?

    I like the looks of these new lights but I also love SF knurling and feel kinda sad its gone. Also no more modularity with the P60 platform with the dedicated sealed heads and new style body means no more cost effective upgrades which is a bummer also.

    I still want one but I am a bit melancholy

    As long as SureFire continues to offer their incandescent line there will drop-in hosts. But these new models are smaller brighter better than dragging on with backwards compatibility with incandescents.

    the FC/CE seems to exist on the bezels of the new lights, the Z2-S review had the same style and location. I don't recall seeing it on my older lights, on the A2 its tiny

    When surefire decided to break compatibility in the circuit designs in their KX heads I'm beginning to notice the entire style to which these new lights are designed have changed entirely...I can't speak for others but I think I'll stay on the wall until my existing surefire's wear out or if there are any good deals on surefire's old line of lights

    I'm interested to know whether the flat part of the reflector makes any difference in the spill beam, especially when considering the height of the reflector and the viewing angle of the K2. And how is the tint?

    Considering that typically a "reel" of LEDs consists of about 1000, if their R&D bought a truckload of reels it would take quite some time to finish the supply, and by then they could discontinue it to merge into newer LEDs and update the specs without discontinuing the light. A good example would be the shift from LuxV KL4s into SSC P4 KL4s

    Thanks for the review. I'm interested in what the tint is too.

    It looks like the Z2-S and Stratum may share the same bezel. Certainly, the reflector design looks the same as does the bezel retaining ring and markings.
