    Cool Spartanian II Review: BEAMSHOTS, RUNTIMES, COMPARISONS, etc.

    Reviewer's Note: The Spartanian II (S2) was supplied by CPF user neoseikan for review. This is a pre-production sample. For more information on this light, please see neoseikan's announcement thread, or his new pre-order thread in CPFMP.

    Part I: Build Overview of the Spartanian II



    The Spartanian II is a new custom-light supplied by CPF user neoseikan. The sample reviewed here is the near-final version. There are no expected changes to the circuit or UI for the shipping version - just some build/anodizing improvements. According to Neoseikan, here are the current and final stats:

    Sample version (with expected final updates):
    • CREE Q5 emitter
    • 6061 Aluminum (final version ALCOA 6061-T6 or 6063-T6 or 7075-T651)
    • HA (type III), "Zebra" two-toned finish (final version will offer choice of Zebra/Black/Olive/Gray with improved HA and better finish)
    • Throw reflector (final version with improved focus)
    • 96% UCL (final version 98%)
    • Single o-ring in tail (final version double o-rings in head and tail)
    • Gold-coated tail spring (final version improved spring/coating, may improve runtime due to reduced resistance)
    • 13 brightness levels from 0.4mA to 700mA, bidirectional adjustable
    • 2 separate adjustable temporary/constant ON positions
    • Battery voltage indicator
    • Low voltage warning and protection
    • Basic knurling (final version with improved knurling)


    Note that the light uses RCR (16340) batteries only - primary CR123A are not accepted. But the light features reverse-polarity protection, so you don't need to worry about frying your light if you accidentally put your battery in backwards. It also features a low-voltage battery protection system, so you can safely run unprotected Racers in this light. There are a few other interesting features to the circuit that I will discuss in the User Interface and Discussion sections.

    Also note that this light is not a traditional twisty - it actually sports an innovative spring-activated switch in the mid-section of the light to control all its functions (see User Interface section later in this review).

    My review sample came alone, in a padded envelop. I don't know what the final packaging will look like.



    Above is a comparison pic up against other 1xCR123A/RCR lights. From left to right, the Spartanian II, JetBeam Jet-II PRO IBS, Lumapower D-mini Digital (Q2), Novatac 120P, and NiteCore EX10.

    Characteristics:

    Weight (without battery): 68.0g
    Length x Width: 89.5mm x 30.3mm (bezel) or 22.3mm (thinnest portion of body)



    As you can see, the light has a fairly unique build and design. The "zebra" pattern on these pre-production samples is due to limited availability of anodized components, AFAIK. I believe the final shipping version will have a choice of the various colours, including the zebra option.

    Fit is very good on my sample, although the anodizing has some imperfections (i.e. mottling on the natural portions, a few chips on the black). These are expected to be corrected on the shipping versions. There is no obvious clip or lanyard attachment point, so you will need to carry the light in a pocket or a suitable pouch.

    The light fits comfortably in the hand and it is easy to carry out all the functions one-handed (either left or right hand). See below for a discussion of the interface.

    Although Neoseikan considers the knurling "basic" on these samples, it is more aggressive than most other lights I've come across. I suspect most users would be happy with it as is.





    As you can see from the head shots, this light has a deep smooth reflector that should produce considerable throw. My sample features the new "silver" backed Cree that comes from the Asian Cree assembly plant. There is some discoloration at the base the reflector near the emitter (at about 3 and 9 o'clock in the full frontal pic), but this hasn't affected the beam pattern.





    The light has a twisty tailcap with anodized body threads in the tail (allowing tailcap lock-out of the light ). A thick gold-plated spring provides the battery tension. Tailcap threads are smooth and clean, although they were shipped dry and needed a little lube. You will need to twist the tailcap to save default output settings for the light (see below for a UI discussion).



    Here's an over-exposed shot showing you the circuit components in the head (picture taken down the barrel of the body tube). Note that neoseikan recommends not removing the head, since damage to the circuit board could occur (not sure if this will be different in the shipping version).

    Features:

    This is where it gets interesting. The Spartanian has 13 discrete output levels - and uses both current-controlled and PWM to produce its low modes. See Part II for a list and graph of the relative output levels.

    From L4 through L13 (i.e. the 10 highest output levels), I can detect no sign of PWM flicker by eye or through my setup. Neoseikan confirms the light uses a standard current-controlled mechanism in this range.

    On the lowest three output levels (L1 to L3), PWM is detectable (although not overly obtrusive) at a measured freq of 127Hz in my sample. This is an interesting hybrid design - current-control is known to be more efficient than PWM, but typically can't go to as low output levels. By combining both into one circuit, the Spartanian II gets the best of both worlds. This is the first time I've come across with this interesting combination.

    User Interface:

    Although the novel UI may seem complex at first, it is actually quite simple and quickly becomes intuitive.

    Simply put, the light has two set states that you can reprogram - and either one can be accessed directly from off. The light uses a spring-activated control switch, accessed by twisting the middle section of the light.

    For momentary-on at either of the two set levels, simply twist the mid-section to the left or right and hold. The left and right positions are the two set-able states of the light. Release the mid-section, and the light shuts off.

    If you hold the light in the on position for more than a few seconds, the light will flash briefly to indicate it is set to remain on once you release the switch. The time required varies for two sides - about 5 secs for the left position, about 1-2 secs for the right. This is apparently deliberate so that you can set one level for momentary on without an immediate lock-on (i.e. to the left), and one level to quick lock-on (i.e. to the right).

    Once the light is in the remaining-on state (for either the left or right positions), you can alter the light output by doing a do a quick twist-and-release switch to the left to reduce the brightness level a step, and a quick switch to the right to raise the level. Apparently, neoseikan can provide lights with circuits customized for left-handed use (i.e. reversed hand-operation of switching).

    To set a new default level for the left of right states, simply unscrew the tailcap once the desired level is reached. This will turn off the light and activate the memory for that side (i.e. whichever side you turned the light on in). Note that you can do this maneuver single-handed: just pivot the light so the reflector opening is toward your palm, and you can twist the tailcap loose/tight. I found this quite easy to do by simply grasping the thinnest part of the light between my thumb and index finger, spinning it around, and then re-grasping so that my thumb and index finger can access the tailcap.

    To turn off the light, twist the mid-section switch to the right and hold for about 2-3 secs. It's necessary to hold it that long so the circuit knows you are not just trying to do a brightness step increase.

    Finally, the do a battery check, twist to the left and hold. It will flash a number of times to let you know the relative battery life remaining.

    I found it quite intuitive and easy to use once I got used to the rapid twist needed for switching.

    Part II: Comparison Review


    From left to right, the Spartanian II, JetBeam Jet-II PRO IBS, Lumapower D-mini Digital (Q2), Novatac 120P, and NiteCore EX10. Although not shown, I'm also including the RCR-only Horus FD-1.3 in the runtime comparisons.

    Comparison Beamshots:

    Both lights are on 100% on AW protected RCR (3.7V, 750mAh), about 0.5 meters from a white wall.





    I've only chosen the Jet-II PRO IBS and D-mini Digital for the beamshot comparisons since the Spartanian II is a dedicated thrower, just like those lights. As you can tell from the hotspot, it clearly throws as well as the competition (scroll down to the summary tables for detailed center beam lux values).

    Beam profile is somewhat ringy, which is not surprising for a thrower with a smooth reflector. Personally, this has never bothered me in the least, since it's not noticeable in actual use. Spillbeam is fairly narrower compared to the other two, but there is an additional dimmer corona of light outside the main spill beam. Although not noticeable in the pics, the center beam has a more definite "spotbeam" appearance than most reflector light. Tint is very white on my sample, if slightly on the cooler purplish side.

    Testing Method: All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlightreviews.com method. You can directly compare all my relative output values from different reviews - i.e. an output value of "10" in one graph is the same as "10" in another. All runtimes are done under a cooling fan, except for the extended run Lo/Min modes which are done without cooling.

    Throw values are the square-root of lux measurements taken at 1 meter from the lens, using a light meter.

    Throw/Output Summary Chart:





    As you can see, the Spartanian II is indeed one of the best 1xRCR throwers in my collection. It exceeds my D-mini digital, and matches the Jet-II PRO IBS (which, to be fair, is driven at a higher output level than the other lights here).

    But even more impressive is its low mode - it can actually go slightly lower than my Novatac 120P (which has a lowest setting of 0.08 lumens). In fact, based on the calibration of my lightbox using the 120P, I'd estimate the Spartanian II's lowest level to be ~ 0.06 lumens!

    Output Levels:



    As you'll recall from my UI description, the Spartanian II has 13 discreet output levels, and uses PWM for the lowest 3 (current-controlled for L4 and up). As you can tell from the graph, there's a bit of a jump when you switch from PWM to current-controlled (i.e. from L3 to L4), but otherwise all levels are well-spaced and visually linear overall. For resolution purposes, I've blown up the lower PWM output levels in the insert graph on the top left. Note that this visually linear relationship is in contrast to the Novatac 120P, where output levels are directly based on lumens (and hence visually curvilinear to human eye).

    This hybrid of PWM and current-controlled is very interesting, and should net the best arrangement of output/runtime-efficiency and lower low modes.

    Output/Runtime Comparison:

    To begin, below is a graphical comparison of five output level runtimes (L3, L4, L7, L10, L13 - counting from the dimmest output levels on up). All runtimes are on AW protected RCR (3.7V, 750mAh). I've also included one L13 run with an unprotected Ultrafire battery (3.7V, 880mAh) to test the built-in low voltage battery protection feature. Note that L3 and lower (still pending) are PWM-based, while L4 and higher is current-controlled.




    Below is how the Spartanian II stacks up to competition. Also included in these comparisons is the direct-drive Horus FD-1.3, since it was also RCR-only.






    Output/Runtime Comments:
    • The Spartanian II circuit produces one of the best regulated output patterns I've ever seen - at all the output levels tested so far.
    • There are no surprises in output/runtime efficiency at any level I've tested so far - performance is good to excellent across the board.
    • The hybrid PWM and current-controlled circuit is very innovative, and seems to deliver on the best of both worlds.
    • Performance is generally on par with the best regulated multi-power 1xCR123A lights. Perhaps a bit less on max, but the Spartanian II seems to match or pull ahead of the crowd on medium-low modes.
    • In comparison to the other RCR-only light in this review (Horus FD-1.3), the Spartanian II holds its own well. Although the direct-drive Horus runs longer on max (as you would expect), performance of the fully-regulated Spartanian II seems to match or even exceed it at the medium output levels.
    • The low-voltage protection feature for unprotected batteries works well in my tests - and nets you extra runtime, since unprotected batteries typically have higher storage capacity.


    Part III: Preliminary Discussion

    As you can probably tell, my initial impressions of the light are quite positive. I find the interface intuitive and easy to use. The spring-activated switch is novel and interesting (I see some have started calling it a "jog-dial"), and worked well for me. My personal preference would be for a slightly stiffer spring (i.e. so it wouldn't move so easily and potentially come on accidentally), but this is a minor point. Overall ergonomics fit my hand size well, and I have no difficulty performing all features single-handed (including setting default states), with either the left or right hand.

    Strengths

    The throw is excellent - although it could probably be slightly improved given the size of the reflector. But it is great as is, and is one of the best throwers in my collection - better than the D-mini, about the same as the Jet-II PRO (which, to be fair, is driven harder, so the S2 performance is quite impressive). The Cree rings don't bother me at all, but they are somewhat more pronounced than most lights (in keeping with its smooth, deep reflector).

    Even more impressive is the lowest level - it is even lower than the lowest output of my Novatac 120P. As I estimated earlier, I would say the S2 goes as low as 0.06 lumens. Very impressive.

    I'm also impressed by the innovative dual current-controlled and PWM-controlled low modes. This gives you the improved output/runtime efficiency of current-control for the lo-medium output modes, and the ability to run truly ultra-lo low modes with decent PWM efficiency. I hope more makers think to try this sort of hybrid approach (although I would personally like a bit higher PWM freq - 127Hz used here is ok, but really only minimally acceptable IMO). The combined 13 output steps are visually linear, which is useful.

    Runtimes are quite respectable at the higher levels - and excellent at the lo-medium range (at least as good as the Novatac or NiteCore Extreme, but of course those are multi-power lights). I get even better runtime on unprotected batteries, and the low-voltage cut-off feature of the circuit works well. And I am sure the members here will be particularly happy by how well regulated the light is at all levels - better than the competition, frankly (although again, it is RCR only).

    Potential Issues

    The main limitation right now is the inability to run primary CR123A batteries. Hopefully the makers will be able to add this feature to future revisions. The spring-activated control ring is also a new design, so time will tell in regards to its long-term stability - it certainly worked consistently well during all my detailed testing this past week.

    The only other issues revolve around some of the build and finish aspects of the sample - but as indicated at the top of this review, these will be revised in the final shipping version (e.g. anodizing quality). I'd also recommend some more interesting styling around the grip ring (knurling is good, but it doesn't need to be fully knurled). A hole in the tailcap for a lanyard, or some other attachment point for a clip, would also be a good idea.

    (Preliminary) Conclusion

    I'm still doing runtimes of the ultra-low PWM modes, but so far I'm impressed with the output/runtime efficiency and regulation at all levels. A lot of thought has obviously gone into the design of the circuit and UI, resulting in an innovative new design for the flashlight world.

    Although continuously-variable lights seem to be all the rage these days, the 13 discrete levels here certainly give you a wide enough range to play with. And in addition to being accessed sequentially and visually linearly (i.e. much like a ramp), you also get two set-able default states you can easily program. Personally, I tend to program my multiple saved-state lights to run in a Low-Med-Hi sequence anyway (e.g. JetBeam IBS lights, Liteflux LF5XT, Novatac 120P, etc.), so the S2 design suits me well.

    With the promised fit and finish improvements, the final shipping version of this light should be a popular addition to a flashaholic's arsenal.

    Thanks for a great review. Also thanks for taking a photo of the butt of the light, which I did not see on any other reviews so far and was curious about.

    A couple things mystify me:

    #1 - this is a thrower, so why is there a need for such a low level of output? The lower levels are needed only for EDC purposes, so a thrower would not really require an ultra low setting. IMHO the thrower is not as well suited for EDC than a floodier light, for most people. So the lower outputs will be mostly unused in most cases?

    #2 - The low level is even lower than the EX10, which I find to be super low already. Is it really necessary to have it go that low? I find the lowest level on the EX10 / D10 to be very low, and any lower would really not be that practical.

    Thanks again for the great photos and review.

    Thanks for yet another good(perfect) review.

    I would also like the light to support primary CR123 cells, but the problem may be the under voltage detection. The light probably need some way to switch it on or off.

    Is the low voltage protection the reason that it cannot run with CR123A primaries? If not what drives that restriction?

    That's a good point - in practice, I find the EX10/D10 is about as low as I normally want to go for normal use. But the major exception is middle-of-the-night waking, where I have completely dark adapted-eyes. Then, I must say that my nightstand light - a SSC-modded CPF multi-level (basically a rebranded VB-16) - is useful for its exquisitely low low modes. It can go even lower than this light (although I don't typically need its absolute min for navigating my bathroom in the dark ).

    That would be my guess. I believe Horus had a similar issue with their RCR-only light. But I will leave it to neoseikan to provide further info - there may be other factors at play that I am not aware of.

    Thank you selfbuilt for this great review. I have some words additional

    1. About left handed version
    I myself is left handed and we think S2 should have a left handed version for peaple like me. S2 is left handed compatible (LHC) and we can produce a left handed version easily.

    2. About circuit improvement
    We are making final improments including circuit improvement. Most of them are on overall stablily, reliablity and quanlity control. A few of them are focused on efficency.

    3. About ESD
    Touch the circuit directly without any static protection is STRICTLY FORBIDDEN and may cause serious damage to the circuit.

    4. About runtime
    We are happy to see you got a 49min runtime of lvl.13, which is equal to our record in the lab. It shows the other parts such as tail spring do not make a big power loss. We are making some improment on manufacture technics to assure every part works well. We suggest battery without protection for S2 cause we have a very reliabe low-voltage protection function.

    5. About low level
    The first version of S2 do not have the lowest 3 lvls and start from 50mA driving current. If you never use low level or ultra low level, just do not twist to left so much times

    6. About CR123A compatibility
    There are two different ways for us to go: one is CR123A compatible and without low-voltage protection, the other is CR123A non-compatible and with a low-voltage protection. We chose the second way cause we do not want you ruin your battery without protection. Maybe we can develop a CR123A-only version of S2? I will do some measurement on CR123A and try to give a proposal to evaluate.

    Your already have some place to store data in, would it not be possible to store if low voltage protection was on or off.
    To make it easy your could deliver the light with protection off and automatic switch protection on if your detected a battery with more than 4 volt and require a special sequence on the ring to disable protection again.

    This proposal will only work if your protection is in software, if it is in hardware, it would probably not be possible.

    Thanks for all your detailed input Kurapica - it's always nice to see the circuit designer join in on the discussion!

    As to the CR123A compatibility, correct me if I'm wrong, but I suspect the general issue here is the difference between western and asian markets. I've noticed unprotected batteries seem to be widely available (and widely used) in asian markets. But most people in western markets use primary CR123A, or protected Li-ions. It's the relative advantage of one approach for one market, and the opposite for the other.

    I think HKJ's point about allowing the user to select whether or not the low-voltage protection is on is great - if it's possible (which it may not be, as he pointed out). Otherwise, maybe the option of selling two different circuit models so the end user could choose?

    P.S.: I'm a lefty myself, so appreciate the thoughtfulness of offering the reverse orientation. But I actually find it more natural to use the light left-handed as it is.

    Rats...I was so hoping this light would take standard 123A batteries. I'd be for deep-sixing the low voltage protection and not having to give up standard batteries.

    Just updated the main post with L3 runtimes - almost 29hrs on an AW protected, not bad.

    Oh, and I see neoseikan has just started his pre-order thread CPFM, with tiered pricing depending on order number.

    I'm looking forward to hearing more about possible CR123A circuit development - I think that will be a real winner here. But I'd like hear what everyone else thinks - that's one of the main advantages having these discussion threads continue after an initiall review.

    Excellent review, I'm very intrigued with this new control style and what it means ergonomically speaking. One of the biggest advantages to the rear clicky is that you always know where the switch is. The ring switch of the S2 eliminates that question while still allowing you to carry the light in a more relaxed position. very interesting in concept and I can't wait to see it in practice.

    I definitely agree with you however in the desire to see CR123A support. I use them exclusively at the moment. It may be time to look into some RCR's. It is always a big bonus though to be able to pop in a primary if the rechargeable dies and you don't have time to recharge or have a backup ready.

    The only reason I haven't picked one of these up is because of the lack of primary CR123 support. If it was able to use primary cells it would be unreal!
    For what reason did they build the light around rechargable cells?

    Great review by the way!

    Woohoo! I love these custom lights that give you great build quality, but at a very reasonable price. Spartanian II, meet my other cool custom, the BitZ.

    I'm in for the pre-order. Can't wait to see pics of the final colors.

    Did I miss something, or does it really take 2 seconds to turn this light off? Personally, when I decide to go dark, I want it immediate.

    You read that correctly. As an alternative, you could always twist the tailcap for an immediate off - but that would mean also saving your current state for that side.

    I think the left momentary ON will help.

    I definitely agree with you however in the desire to see CR123A support. I use them exclusively at the moment. It may be time to look into some RCR's. It is always a big bonus though to be able to pop in a primary if the rechargeable dies and you don't have time to recharge or have a backup ready.
    Just a little thought to the logic flaw there. If your primary dies then you have to have a primary battery as backup to keep using it. So either way you need a backup - might as well be a rechargeable so we can quit dumping in the landfills. I've gone almost totally Recharageable and have enough so I've always got a backup and enough chargers that will run on almost anything from AC to 12V to solar so no reason for having a bunch of primaries sitting around gathering dust. Get some RCR's - you'll be glad you did and you've got guilt free lumens

    Now for you selfbuilt - you've really got to stop doing these reviews! They are like a super AD and are doing serious damage to my wallet

    Although I know that was meant as a tongue-in-cheek compliment, I should re-iterate for the newer members here that it's never my intention to serve as an ad for any particular light or company.

    I'm all about providing objective test data in a consistent manner between lights, to let users make their own decisions according to what features matter to them. Although I do make some subjective/personal comments at the end of my reviews, these are just my personal opinions (and are intended more as an aid in helping you decide if a light is right for you). I've yet to come across a "perfect" or "ultimate" light in any category, but I do like to give credit when I see innovative solutions being offered. As always though, you need to be balance that against other limitations or design choices that may not suit your particular use/need.

    FYI, this is also why I don't use a fixed point/star rating system or value-for-money analysis. Those are certainly very useful when trying to rapidly drill down to a conclusion about a light ... but I find it very hard to do those objectively, so I prefer to leave that personal decision up to each of you. And of course, all of this is typically based on n=1 sample light, so you need to take all the results with a great big grain of salt.

    Short version response: I guess you are going to continue to be stuck with my rather verbose descriptions.

    FYI, I also think the real value of CPF is in the all the discussions that ensue following a review. For example, I can give the Spartanian makers personal feedback that I think CR123A support is important - but that's just one opinion. If this is a broader concern to the community (which I think it is), then the responses here and in other threads should make that view clear fairly quickly. Internet democracy in action ...

    I was of course just razzing you about it being an Ad - and we all totally appreciate the hard work you do in putting together some of the best reviews on CPF. I've just been on a buying binge lately and had to find some one to blame it on

    Keep up the great work

    selfbuilt great review as always.

    With the absence of a lanyard attatment,I'm thinking would one of thesefit would the tail tighten down enough for the light to come on

    [edited]sorry I forgot to mention the ID of the ring.
    size is 23.5mm ID x 1mm thick.

    Well, it would fit, but then you wouldn't be able to turn on the light.

    The S2 is only 21.0mm across at the point just below the o-ring but before the raised "lip" of the body (which itself is 26.0mm - and is flush with the tailcap when closed). So yes, it would fit (albeit loosely when tailcap is unscrewed).



    But unfortunately, you would be breaking contact with the tailcap (i.e. tailcap threads are anodized), so you wouldn't be able to turn on the light. To compensate, you would need to put a 1mm contact disc (i.e. equivalent height to the ring) in the tailcap.

    And I should warn you that tolerances are pretty tight - a miniscule unscrewing of the tailcap right now, and it goes off.

    Here's why.

    You have this light with you and something happens and you're in an extreme survival situation where you will be stuck somewhere for days. That's when you'll feel the need for the super low level.

    Situation number two. You run into an emergency thing like above and you really don't have much battery left in the light. The low level CAN be useful and save your butt.

    Personally, I've started rethinking buying lights that are say above 50 bucks each. If they don't have a super low level, I won't buy them.

    Then if I have one or two extra batteries and one of these lights, I can go pretty much anywhere and have workable light for days and if not weeks.
