Leatherman Serac series review, for consideration for the flashlight review subforum
by carrot

Full disclosure: I was contacted by Leatherman and asked if I were interested in reviewing the Leatherman Serac series of lights. I received the lights free of charge directly from Leatherman on the understanding that I get to keep the lights if I allow them to use my review/photos freely. I was never advised as to what the content of the review should be. Despite receiving these specimens for free I have attempted to be as unbiased as possible in my review.

(more photos coming soon)

As many might know, Leatherman entered the flashlight world last year with the Leatherman Monarch series of lights, to little fanfare. They never got very popular, probably due to their large size and usage of multiple AAA batteries instead of the more popular CR123, AA and single AAA form-factors.

Leatherman learned their lesson and went back to the drawing board. This year, Leatherman introduced the Serac series, designed to appeal better to the outdoorsman and flashlight enthusiast, and hopefully the general public. The Serac series is truly worthy of the Leatherman name, a company that built its reputation on premium multitools.
Today I am reviewing the Leatherman Serac S1, S2, and S3, which currently represent the entire Serac line, as of October 2008. The style of this review will cover an overview of the entire line (when possible) on several key points and then "drill-down" to examine the different features of each light where the product features diverge.

Quick rundown:
Serac S1 -- 1xAAA, Nichia GS LED, 6 lumens*, 11hrs
Serac S2 -- 1xAAA, Cree XR-E 7090 LED, 5/35 lumens*, 10.5hrs/45mins
Serac S3 -- 1xCR123A, Cree XR-E 7090 LED, 7/43/100 lumens*, 36hrs/4hrs/1hr
* manufacturer estimate (using alkalines for S1 and S2 and a regular CR123A for S3)

Independent verification
CPF user Chevrofreak independently tested these lights and got the following on primaries (alkaline AAA and lithium CR123).
Serac S1 -- 7 lumens, 12.8 hours
Serac S2 -- <8 lumens, 6.4 hours / <55 lumens, 17.7 minutes
Serac S3 -- 6 lumens, 57 hours / 47 lumens, 5.5 hours / 110 lumens, 1.3 hours

For the S1 and S3 this corresponds to Leatherman's estimates favorably, actual tests performing better than Leatherman's estimates. For the S2, runtimes seem grossly overrated.

I found in my own experiences that the S2 does appear to run for at least 30 minutes on high with alkalines in an informal test so maybe Chevrofreak's sample is a fluke, especially when considering Leatherman's other two estimates were spot-on.

You can see Chevrofreak's detailed runtime graphs here: https://www.candlepowerforums.com/threads/212996

Measurements:
S1 - 3.23in / 8.2cm
S2 - 3.48in / 8.84cm
S3 - 3.2in / 8.13cm

Light Output and Operation:
I have no light meter with which to verify the manufacturer's claims on light output but based on experience it appears that the estimates are not far off from reality, and in fact are probably fairly accurate. Leatherman's quoted runtimes also seem fairly viable, which I've listed above. Hopefully Leatherman will send a sample to Chevrofreak so he can independently verify their claims.

The Leatherman Serac lights are extremely easy to operate and should be easy to figure out for anyone, from grandma to "Joe Sixpack" to a flashlight aficionado. On the multi-level lights (S2 and S3) a light press or half-click on the clicky switch allows the user to switch brightnesses. Contrary to some rumors, both the S2 and S3 always on the lowest mode and each subsequent half-click cranks up the output, or reverts back to lowest once the highest level is reached. They DO NOT, in fact, save the last used level, to the relief of user interface experts everywhere.

I have a wooded area that is pretty devoid of light that I went to go test the Serac lights in. I walked around for a bit with each one and I can say that I would not feel naked or insufficiently illuminated if I only had one of these lights on an outdoor expedition.

The S1 is quite sufficient for walking around and reading, but the Nichia GS LED can only put out so much light and I often wanted to see out just a little further. However, its long runtime and useful output makes it an excellent backup light.

The S2 is definitely an excellent contender for a primary EDC (every day carry) as it is capable of cranking out a surprising amount of light when you need it and also offers a long runtime when high output is less important. I was able to comfortably walk around the forest with the S2 running on low and even identify "landmarks" by the patterns in the trees. Being able to quickly jump to high mode with a half-click was great and comforting when I heard barking off in the distance. My only concern is that with the S2 it is all too easy to want to kick into high mode and burn the battery down (only 45 minute runtime) so I felt continually conscious of the slowly depleting battery. Carrying a few spare batteries would certainly alleviate this concern.

One caveat with the S2 is that if the (alkaline) battery has been sufficiently drained it can still put out light but if you turn it off then turn it back on it will refuse to light until the battery has recovered a bit. A little disconcerting, although expected on a high-drain AAA flashlight. This effect should be far less pronounced on other chemistries like NiMH and Lithium. The other problem is it uses PWM for low. It is not as noticeable as some other lights I've used, so it doesn't bother me too much, even when moving, despite the fact that I am fairly sensitive to PWM.

The S3 is a beast of a light, as far as tiny pocket lights go. It has no problem reaching out and lighting up distant objects thanks to the deep reflector and offers three very useful brightness levels. Low is excellent for close up tasks, medium is great for navigating around and high is good at spotting distances when you hear noises or want to impress your friends. This is probably my favorite of the three Serac lights and gives my $450 custom a run for the money as far as being the perfect EDC light. CR123A batteries are a "funny battery" for anyone not a flashlight aficionado, however, so hopefully Leatherman can exercise its brand and sales prowess to make CR123A a more mainstream battery.

-- S2 and S3 --
When I first turned the Leatherman Serac S3 on, I was extremely impressed at the quality of the beam. It features a fairly tight hotspot for better throw (ability to light up objects at long distances) and a nice gradual transition to spill (the dimmer area around a hotspot). This gorgeous beam pattern is thanks to the textured "orange peel" reflector that is used in both the S2 and S3. When I turned on the Serac S2, I was equally impressed. For the record, my particular samples of S2 and S3 had a fairly neutral cool white tint.

Why is a good, smooth beam important? Artifacts in the beam can make weird shadows or make the user "see" movement where there is none. A smooth, gradual transition from hotspot to spill is more useful for a general purpose flashlight because the smooth transition makes the flashlight easier and more comfortable to work up close and read with, as well as navigate trails and paths more easily, without sacrificing too much throw. Simply put, such a beam makes for an excellent and versatile flashlight.

Design and Build Quality:
Each of the three lights is hard anodized 6061-T6 aluminum (commonly called aerospace-grade) with a stainless steel bezel and features a clicky switch located on the back for quick activation and ease of use. Each light also comes with a reversible pocket clip and offers some form of keyring or lanyard attachment. The pocket clip is an often overlooked feature on many competitor's flashlights but Leatherman nailed it with theirs, well-designed and perfectly executed. Since these lights are so small (but not underpowered!) a pocket clip becomes one of the most convenient methods of carry. They are an aesthetically pleasing silver and black, and should age (wear in) gracefully. The lights have a nice sturdy feel and the matte finish makes them easier to grip. I had no problem drawing and using the lights with or without gloves on. Another neat feature of the pocket clip on all three lights is that they are strong (stiff) enough to be used on a baseball cap in lieu of a headlamp.

The tailcap, which contains a reverse clicky switch, is user-removable for easier cleaning of the interior of the light or for switch replacement. The clicky switch has a very robust feel and forms a silicone rubber seal for water resistance. All three lights are capable of tailstanding for use as a "candle" of sorts. You can replace the battery by removing either the bezel (head) or tailcap, but it is easiest to replace through the bezel, which is textured for grip. To reduce the chances of accidental activation, you can unscrew the bezel partially.

-- S1 and S2 --
The S1 and S2 feature the same pocket clip and keyring attachment, which makes sense considering that the S2 is just .25" longer than the S1. The pocket clip is extremely well-designed and allows the light to ride low and discreet, allowing for excellent pocket retention. The minute size and excellent clip on these two AAA lights make them well-suited towards discreet carry in dress attire and would be practically unnoticeable in a suit or summer shorts. You can also reverse the pocket clip if you desire to carry the light bezel-up.

The lanyard ring, or keyring attachment is also detachable -- it clips into a ridge on the light and allows you to remove the light from your keychain quickly and easily. Should you choose not to use the lanyard ring, it smartly doubles as a retainer for the pocket clip, preventing it from sliding off.

dsc00828mh6.jpg


A cool thing about the S1 and S2 is that despite having having a clicky activation switch on the back, they still can tailstand. One problem I foresee is that the S1 and S2 actually tailstand on the silicone rubber button, so over time as the button wears down it may become unable to tailstand. As the lights are new, I cannot say whether this will actually be the case. Still, some tailstanding is better than none at all.

dsc00832xy2.jpg


-- S3 --
The S3's pocket clip is equally impressive in design -- it is a wire clip similar to that which has become recently popular amongst knife enthusiasts for the discreet carry and comfort during use. A small metal ring gives the wire clip tension to hold onto the light and allows the user to easily switch the light from bezel-up carry to bezel-down, which I prefer on most flashlights, again, for greater discretion and better pocket retention.

Conclusion:
Before I got the Leatherman lights I was readying myself to tear them apart in my review ("Leatherman makes flashlights now!?") but -- when I actually received them I was extremely impressed with the careful attention to detail and thought that went into designing these lights. I really like the three Serac lights and I'm glad I got the chance to review them. To those of you thinking of passing over the Leatherman Serac series because Leatherman hasn't traditionally made flashlights -- don't overlook these excellent lights!

They are every bit as good as established competitors in the same price range and add some unique features that make them worth a second look. There are quite a few lights that are similar to the Serac series but the excellent design sensibilities of this Oregon-based company really make them shine. When Leatherman decided to make a new series of lights they really took it seriously and have a compelling product to show for it.

I would really like to see Leatherman offer a 1xAA light seeing how AA batteries are the most commonly available and offer quite a bit more power capacity over common AAA batteries.

I brought the Serac trio to Photon Fest 11, an East Coast flashlight aficionado gathering, and the response was positive. Many jaded flashaholics showed interest in the Seracs and for good reason -- they offer an attractive set of features at a reasonable price.

TL;DR version:
What makes the Leatherman Serac lights special and stand out over the other competitors is: stainless steel bezel, pocket clip, innovative keyring attachment (S1 and S2 only), clicky 1xAAA light, great beam quality, extremely simple to operate. Highly recommended.

Pricing:
MSRP lists the S1 at $30, S2 $55, and S3 at $80. However a quick search reveals that the average price is $25, $50, and $70 respectively. I think this is fairly priced and within the same range as competitors. As of the time of this review, Serac lights have not yet shipped to online retailers but may be found in some brick and mortar stores.

Great reviews - looking forward to the pictures.

I think, however, that the "full disclosure" statement should be at the top/beginning of the review. When I read the post, I saw nothing besides a couple of *reservations* that was really negative about the lights....and then read the disclosure...ahhhh...perhaps they are as great as you have described, but I would have read the review differently. Just my opinion.

Good point, but even more than "full disclosure" I look at the output shown in the threads here and Carrot does rate quite well in those regards.

Honestly, I can't find anything to really dislike about these lights. Simple UI, seemingly durable, bright, pocket clips, tailstanding... all of the things I like in an EDC light and these have them.

FWIW, I moved the disclaimer to the top. I would, of course, hope that my reputation for (mostly) reliable information supersedes any doubts as to my bias. Perhaps my viewpoint is biased because I received complementary lights, or perhaps Leatherman sent me the best of the batch, and if anyone believes criticism or comment is missing from my review I will be happy to take it under consideration.

I am glad to hear that. I was worried that it would always start on the next mode. I guess LED Museum didn't wait long enough for the light to reset, which is how that rumor got started. (And I think Doug Ritter's review said the same thing)

Hmm, now who has the best price on the S2.....


PS.
What are the chances of getting a few pics of the S1 and S2 lined up with some other common AAA lights, such as the Arc, E01, LOD, LF2, LF2X, etc.?

Nice review. Does the S3 clip work well for ball cap clipping aka redneck headlamp?

So far the only draw back I see is reverse clickie.
Seems to work fine. Clip is nice and tight, too.

dsc00843rd7.jpg


I tested it with the S2 as well, and it works great.

I don't have an E01 or any LF's. Tomorrow night my friend should be visiting, so I will snap a pic of the Arc, E01, S1 and S2 then.

Edit:
After running down the battery on the S2 I noticed this:
One caveat with the S2 is that if the (alkaline) battery has been sufficiently drained it can still put out light but if you turn it off then turn it back on it will refuse to light until the battery has recovered a bit. A little disconcerting, although expected on a high-drain AAA flashlight. This effect should be far less pronounced on other chemistries like NiMH and Lithium.

I just added that to the main review.

Thanks for the review. The lights are interesting, due to their clips, clickies, and stainless head. It does seem though, that the runtime specs are closer to old Lux lights than anything with a Cree. They do look nice enough to be used as a host, but I doubt I would buy one knowing their specs.

It looks like the runtime specs for the S1 and S2 are for alkaline. Even if they were advertising OTF lumens (who knows, only time and an IS will tell), 35 lumens for 45 minutes is awfully low, and would have to be a hideously inefficient circuit. That is, unless that is the alkaline runtime, which should be spot on. With NiMH or L92's, I would expect at least twice that much.

great review, you need to do these more often :)
I don't like to write reviews about the same light everyone else has written dozens of reviews about and seen dozens of times. I like writing about new things that not many people have seen... Maybe I'll write a review about the McLux PD... or Petzl E+Lite next? Maybe a Milky Mod...

FYI, those are just rebranded Fenix lights... so basically they're kinda the same dozens :p
Not really... I could go on to say Ultrafire and Superfire and Trustfire and Fenix and Olight and Eagletac are all the same but they aren't... I would consider them rebranded if all Leatherman did was take some lights and stamp their name on it but that's not the case here. I consider them better than their counterparts, if only due to small changes.

Why would you call Fenix, Olight and Eagletac the same if they both look and have different circuits?
These on the other hand share the same electronics as Fenix, in addition to looking similar.

Why do I have to argue over things that I already went over in my review?

I consider them different enough from Fenix to be interesting. As I recall, Fenix does NOT offer any AAA lights with clickies, still has NOT released a 123 light with a pocket clip, and insists on including ridiculous modes like strobe and SOS. Does that sound like the exact same electronics to you? Even if they are running different firmware, that is difference enough. If you recall (you probably don't), Henry of HDS lights used to sell the Basic and Ultimate lights for vastly different prices, and the only difference was firmware. Nobody complained. That speaks to me the importance of firmware.

Fenix also does not offer a stainless steel bezel which is better due to resisting deformation, which a lot of people have experienced by dropping their light. To me that says that this is more than a rebrand, which you would have noticed if you'd read my review, and to me, that differentiates them as products in my mind as much as I would ones across completely different manufacturers. Since you seem to have glossed over the details that I paid the most attention to, you are just wasting my time with semantics.

Also, if you ask me, screwing down and unscrewing the bezel to switch modes, while a great UI is just a recipe for disaster seeing how the light engine is screwed into those same threads. I have on several occasion received lights that would refuse to stay in turbo/high mode.

Stop wasting my time.
