Thread: NiteCore Extreme Review - RUNTIMES, BEAMSHOTS, COMPARISONS, etc.

    Grinser2 NiteCore Extreme Review - RUNTIMES, BEAMSHOTS, COMPARISONS, etc.

    REVIEWER’S NOTE: This is a two-part review – the first part is a build overview of the EDGETAC NiteCore Extreme. The Second part is a detailed comparison of the Extreme to other lights of its class, including earlier NiteCore Defender Infinity (NDI). Both NiteCore lights were provided free of charge by EDGETAC for review. They are currently available in Canada at photongears.com and fenixtactical.com.

    PART I: Extreme Build Overview



    As you can see, the extreme comes in the same sort of packaging as the other EDGETAC lights. Included in the sturdy box (with foam inserts and metal closing clasp) are the warranty card, manual, and spare parts (including two extra forward clickies, mini-Allen key and some o-rings).




    Overall design is similar to the NDI, although bulkier and more substantial. This extra mass (and heatsinking fins near the emitter) should help to dissipate heat fairly well. The light features the same “anti-roll” rings as the NDI around the head and tailcap, but the attached clip is really the most useful anti-roll device. The bezel-pointing clip is a new feature on this light, and feels quite substantial. It is removable, attached by a couple of hex screws (mini-Allen key wrench included with the spare parts).



    Build quality is top-notch on my sample – no visible machining marks, anodizing is flawless and smooth. Anodizing is a very dark slate gray natural finish (HA-III), almost black. There is diamond pattern knurling around the main body portion of the light. Lettering is clear and sharp (I'm guessing laser etched). Note the general lack of identifying labels (early version NDIs and RaidFire Spears were a little over the top ).

    Like the NDI, this version of the Extreme features a crenelated bezel with 3 points, allowing you to tell if the light is on when standing face down. Note that this introduces something of a “triangulation” of the spillbeam pattern up close (i.e. looks like a rounded triangle at close range). An alternate version of the light is sold with a smooth stainless steel bezel ring that doesn’t produce this pattern.



    I haven’t tried accessing the head yet, but you can see it uses a fairly substantial heatsink below the emitter (I’m guessing brass). This is very reassuring given the very high output the light is capable of on max.



    There is no separate tailcap portion to this light, so no tailcap lock-out is possible (switching occurs through the head, so no lock-out is possible there either). So, you may ask, how do you change the forward clicky switch if you need to? There’s an exterior switch retaining ring located around the switch boot cover. An interesting design I haven’t seen before.



    One issue with this design is that there is no way to “push” a tight-fitting battery out of the tube – you need to “pull” it out by the positive end. It would therefore be ill-advised to force a protected battery down the body tube. All of my black-label AW protected RCRs fit fine (although the earlier ones are a bit snug). Unfortunately, my blue-label AW protected RCRs seem to be too thick to fit down the body tube. I’d recommend those with blue-labels consider upgrading if you want to use RCR in this light. My gray Ultrafire protected also seems to be too tight a fit. YMMV…

    The forward clicky has the exact same feel as on my NDI, although I haven’t disassembled yet to confirm whether or not they are identical.



    As you can see above, the Extreme uses the new “silver” version of the Cree Q5 emitter (i.e. the area outside central die is silver in color, instead of the standard Cree yellow). My understanding is that there are no output differences between the silver and yellow versions, and these simply reflect different manufacturing plants. Light uses an aluminum reflector with modest texturing (i.e. I’d consider it a medium orange peel, MOP).

    The lens supposedly has a “diamond coating” exterior and anti-reflective interior coating. Obviously, I have no way of testing that, but it looks clear and clean, like all my EDGETAC lights.



    The o-ring between the head and body is fairly thick, making it stiff when tightening the head all the way to the body. Resistance is higher than any of my NDIs, and definitely requires use of two hands to switch modes (scroll down for a discussion of the interface). This may be done on purpose to improve waterproofness. Note the light ships quite “dry” – little or no lube on the threads and o-rings. I know from experience with NDIs to avoid getting any lube on the threads in the head, as this can cause contact/mode-switching problems due to the interface.

    Dimensions:
    Length: 94mm
    Max width (bezel): 26.0mm
    Min width (body): 21.1mm
    Weight: 65.4g

    Size of the light is a bit bigger than I expected, but quite reasonable. Scroll down to Part II of this review for a photo comparison to other lights of its class. But for now, upon request, here's a hand reference shot:



    Since I have rather long hands and fingers, I’ve elicited the help of Mrs. Selfbuilt below (she is petite with small hands).



    Interface:

    Like the NDI, the Extreme uses PWM at an undetectable frequency (i.e. >1 kHz). No signs of visible flicker at any level in my testing. Strobe freq is 9Hz.

    User interface is exactly the same as the NDI. You can set your own user defined mode through a continuously variable brightness mechanism. The light is controlled by a forward clicky switch with momentary on, followed by a click to lock-on. Sequence is as follows:

    • With the head in the fully tightened position, momentary press or click on the switch and you get maximum brightness.
    • To get to the user defined (i.e. lower modes), simply slightly loosen the head a quarter turn from fully tightened.
    • To change the low mode brightness level (i.e. to set user defined level), while in the user defined mode tighten and then loosen the head within 0.5 sec, and the light will ramp up to the maximum brightness (takes about 6-7 secs to run the whole range - see graph below). Loosen and tighten again to get the light to ramp back down to minimum. Switch the clicky off to save whatever output setting you desire (memory mode feature means the light will come back on at that level).
    • To get strobe, start with head fully tightened (i.e. on Max). Loosen and tighten the head within 0.5 sec to enter strobe mode. Note that the light has a memory feature, so it will come back on in strobe if you click it off in that mode. To get back to max, loosen and tighten the head again.

    And that’s it. The whole user interface is quite simple and straight-forward. I’ve always found it very intuitive. Note that due to switching-mode nature of the light, there will be a slight lag if you want to simply go back and forth from user defined to max (i.e. it waits 0.5 sec after you tighten/loosen the head, in case you were in the middle of performing a switching cycle)

    Variable Output ramping time



    Update: I've just done the ramping sequence analysis for the Extreme. As you can see, performance closely matches the NiteCore Defender Infinity (NDI). On primaries, the Extreme seems have a virtually identical ramp to the NDI on 14500. On RCR, I would say my Extreme ramps up about ~1 sec faster. Note that the EDGETAC offerings are lot more visually linear than the Novatac 120P (although that is intentional - the Novatac steps through half-values of 120 and 85 lumens as it ramps).

    Note that unlike some makers, the ramping sequence is very linear in EDGETAC lights.

    For beamshots, throw/output, and runtime comparisons, please see Part II of this review.

    PART II: Comparison of the Extreme to other lights

    For this part of the review, the NiteCore Extreme will be compared to the Fenix P2D-Q5, Novatac 120P, Lumapower Incendio, JetBeam Jet-II IBS, and original NiteCore Defender Infinity (left to right in photo below).



    Beamshots:

    On AW Protected RCR or 14500 (on Max/Turbo/100%) at ~0.5m from a white wall.







    First thing to notice is the somewhat triangular spillbeam of the Extreme, due to its 3-point crenelated bezel (although this less noticeable at further distances, so really isn't an issue in practice). Tint on my sample is very white, with a slight purplish tint. Despite the OP reflector, Cree rings are still noticeable at this range. Note the Novatac 120P uses a SSC emitter, but all the other lights are Crees.

    Despite how it looks in the camera pic above, in real life the Extreme is noticeably brighter than the NDI (confirmed by lightbox and ceiling bounce, see below).

    Testing Method: All my output numbers are relative for my home-made light box setup, a la Quickbeam's FR.com method. My relative overall output numbers are typically similar to his, although generally a little lower. You can directly compare all my review graphs - i.e. an output value of "10" in one graph is the same as "10" in another. Ceiling-bounce tests are done in a small windowless room, with my light meter on the floor near the base of the light (which is shining upward in candle-mode). Throw values are the square-root of lux measurements taken at 1m using a light meter.

    Summary Chart:



    In terms of estimating max total output, I believe the ceiling bounce numbers are the most accurate (my milk carton lightbox tends to underestimate at the really high-end of outputs). As you can see, max output of the Extreme on RCR is considerably more than the NDI.

    The Extreme is in fact one of the brightest 1xCR123A/RCR lights in my collection – second only to the continuously-variable JetBeam Jet-II IBS. FYI, note that output of the Jet-II is underestimated slightly by my lightbox, since it doesn't like really strong throwers. The Extreme is also slightly brighter than the direct-driven Fenix P2D-Q5.

    In terms of minimum output, the Extreme is unfortunately a bit brighter than the NDI, but close to the continuously-variable Jet-II. Note that nothing compares to the Novatac for a truly low low mode. The Extreme also has greater throw than most of the other lights here (except for the Jet-II, of course). I will need to play with the Extreme more at night before I can make any judgements about the usefulness of its beam (typically, I don’t like a pronounced hotspot on low-output lights).

    Weights:
    NiteCore Extreme: 65.4g
    Fenix P2D-Q5: 38.8g
    Novatac 120P: 72.6g
    Lumapower Incendio: 31.3g
    JetBeam Jet-II IBS: 58.5
    NiteCore NDI: 44.1g

    As you can see, the Extreme is second only the Novatac in overall weight.

    Runtimes:

    Note:Like the NDI, the Extreme does NOT have defined medium/low modes – rather, the light uses a continuously variable digitally-controlled brightness level. For the purposes of this review, I’ve manually set the Extreme to a number of output levels for comparison purposes. I’ve labeled these as “-ish” settings, since they are only approximate.

    Note as well that there can be a pronounced difference between RCR and primary CR123A on any one specifically-set User Defined mode. At the higher end of the range, CR123As are just a little dimmer than RCR. But at the low end of the range, CR123As show quite a bit less output.












    *NOTE: Although the Novatac 120P run was started at 15 lumens (level 16), the light output quickly dropped in half to 7.5 lumens (level 14) for the entire run. Not sure why this happened, but I've left the trace in since it gives you a good comparison to the Incendio low level.

    Output/runtime observations:

    • No doubt about - the NiteCore Extreme is one of the brightest 1xCR123A/RCR lights in my collection.
    • Efficiency at maximum output level on RCR is excellent, as good as I've seen. Only the JetBeam Jet-II IBS is able to produce to more light (with lower runtime, of course).
    • On max, the Extreme is noticeably brighter than the NDI when both are run on Li-ion rechargeables.
    • Efficiency on RCR in the user defined modes is also quite good - typically as good or better than the other regulated lights. At the lowest output intensities, the Novatac 120P is only one that beats it.
    • A similar pattern is observed for CR123A primaries – the Extreme is the output/runtime king.
    • At lower output levels, the Novatac is again the best performer – but the Extreme is still quite good up until its minimum setting (runtimes being re-checked, will update when done).
    • In terms of absolute lows, the Extreme doesn’t go quite as low as the NDI or the continuously-variable JetBeam Jet-II IBS.
    • The Extreme features excellent regulated performance on all battery types at all settings tested so far. Note the interesting little output spike on both battery types just before dropping out of regulation.
    • Ramping sequence is relatively linear and very close to the NDI (virtually identical on primaries, and about ~1 sec faster on RCR)
    • Unlike the NDI, I haven’t seen any evidence of a low battery warning on Li-ion on the Extreme. As usual, I don’t recommend unprotected cells in lights that aren’t specifically designed for them.

    Preliminary Discussion:

    Initial impressions are that the Extreme is a very impressive light. Output and runtime are top-notch, judging by the performance on the tests I’ve run so far.

    Build-wise, it is not quite as substantial feeling as the Novatac, but it is certainly hefty and solidly-built. EDGETAC seems to have paid a lot of consideration to proper heatsinking, and the design makes sense to me. The clicky switch access on the exterior of the light near the tailcap switch cover is fairly unique, and the inclusion of two extra clicky switches is generous (forward clickies are known to have a greater failure rate than reverse ones).

    The only body issues I’ve noticed is the fairly tight fit with some protected batteries (e.g. my blue-label AW protected RCRs won’t fit). The o-ring around the top of the battery tube is also a bit thick, increasing the resistance when you try to fully tighten the head to go to max output or perform a mode switch. It is still manageable, but it is stiffer than my NDIs (and I know this was a sticking point for some on the NDI, pardon the pun ).

    There has been some confusion regarding overall output of the Extreme compared to the NDI. In my case, I would tend to trust my ceiling bounce numbers, since I know my milk carton lightbox underestimates output at the very high end. My 3 NDIs all perform very closely to each other, and this Extreme is at least a good ~45% brighter than any of them on max on Li-ion. I typically try to avoid lumen estimates, but if you believe the NDI is around 130 lumens on 14500 (which I think is reasonable, compared to my Novatac 120P), then I would say 190 lumens for the Extreme on RCR is believable. To my mind, this is a perfectly reasonable engineering decision, given the much better heatsinking designed into the Extreme compared to the NDI.

    My only other minor quibbles are the somewhat triangular spillbeam at close quarters (solved by going for the smooth stainless steel bezel version), and the somewhat higher minimum output setting compared to the NDI (although still quite low and pretty close to the Jet-II IBS).

    Personally, I find it a very attractive looking light, somewhat more akin to a custom-built light than a mass-produced one. When you consider the price (<$90) and all the features, it seems to be a good buy in this space. If you want a solidly-built, continuously variable, forward clicky 1xCR123A/RCR light with good throw, very high overall output, and excellent runtime, then this light could be the one for you.

    I'll be updating this thread once I'm back home next week and can play with it some more!

    UPDATE June 2, 2008: Variable output ramping results have now been added to the review above.

    Having played with the light a little more, I find the "triangulation" of the spill beam is not really noticeable in real-world use (i.e. only pronounced at close distances on white wall ).

    In terms of the lowest output mode (which I use the most at night), I find the sharply defined hotspot of the Extreme to be less than ideal. This leads to a bit of the "follow the bouncing ball" effect as you are walking (similar to my comments for the Jet-I MK IBS).

    In this regard, I prefer the smoother hotspot/spill transition of my Novatac 120P and my NDI. I also like the 120P for its much lower low modes. However, I like the proportionally brighter spill area of the Extreme and NDI over the dimmer spill of the 120P.

    The end result for low mode use is that I find the NDI has the best characteristics of spot/spill brightness and transition of all my lights so far. But I'm still playing with all of them, and will keep you posted if I notice anything else.

    For high mode use, the Extreme is definitely the brightest light of those mentioned above, with the best throw (although the Jet-II is clearly the throw king on the 1xCR123A/RCR format).

    UPDATE June 17, 2008:

    EDIT: Just completed the Min output mode runtimes, and my results seem low on primaries. I've checked this EDGETAC, and they are looking into whether its an issue with my specific sample or the final circuit in general. Once they get back to me, I will update this thread with the results. Stay tuned!

    UPDATE October 28, 2008:

    The low mode runtime issue has turned into a rather complicated problem, and one that goes far beyond Edgetac and this one light. Please see my post #216 in this thread for a detailed commentary.

    Nice review selfbuilt. The head looks a little too big for the body. Looks kind of awkward. Have you tried putting the head onto a Surefire E series light? It'll be nice to know which one it's compatible with. Thanks for taking the time for the review.

    Yeah, it would be tough to choose just one.

    The Extreme has a more generally useful beam, since overall spill width is wider. It still maintains very good throw, but nowhere near as good as the Jet-II. Extreme also comes with a forward clicky. And it also looks like the Extreme should have better heatsinking capabilities (although I haven't tested heat measures). But the Jet-II has three memory stages instead of two, and a fairly good beam defocusing feature with locking ring.

    Both are very nice lights.

    thanks, i already emailed my local distibutor about getting one....look like ill just have to get both...the extreme just cos it looks so good,and im an edgetac fan... and the Jet-II cos ive been looking for a pocket thrower after all the fun im having with my tiablo. the moment i saw the head of the jet-II, i wanted it......i could probably sell either on BST well enough if it doesnt work out..

    question, is the throw of the JetII impressive? like " wow, i cant believe something this small throws that far" impressive...

    Thanks for the EXCELLENT data. While I like the Extreme, also confirms the overall great design of the Fenix lights such as the P2D. 2nd smallest, and yet one of the most efficient and very close in total light production as the two latest and greatest. (Extreme & Jetbeam)

    Super review. Thanks.

    I would say yes. It throws further than my T1 did, and nearly as far as the first batch of Regal WT1s. For that matter, it throws about as far as the first P4 version of the MRV did! Very impressive in such a small size.

    But the Extreme is a surprisingly decent thrower - a bit too much perhaps, since I tend to like a floodier beam in this size light (e.g. Novatac and Incendio).

    It's true, Fenix is always the leader when it comes to output/runtime efficiency thanks to its current-controlled circuit (although you'll see here the Extreme seems to match or beat it, especially at the high end of the output range).

    The problem with the P2D circuit in this context is the lack of defined levels on RCR, and lack of a true low mode. Which also helps explain Fenix's efficiency dominance on regular batteries - it's a lot easier when you don't need to design-in regulated support on a wide range of input voltages. Fenix's efficient current-controlled circuitry also isn't amenable to low output levels either. But if that doesn't matter to you, the P2D is great light.

    The EXTREME beam shots here and elsewhere appear to have the typical Cree Q5 black donut around the hotspot. I wonder if it is obvious in actual usage as is it is the photographs. Its strange but my second NDI from a more recent shipment had less of this than on my earlier NDI, with which the beam shots of the EXTREME look more similar.

    +1 to that!

    Looks like a great little light - I like the stainless bezel version in particular.

    Thank you for your great review.

    Wow looks great. Thanks for the great review! Love those graphs, very informative. I've got the Jet II IBS . Really like the Jet II and I'm looking forwards to trying out the extreme (SS version)!!!!

    Excellent review Self Built

    In my case the runtime on MAX for hot off charger battery is 49 minutes and the same test done after 1 day from fully charged is about 47 minutes. That's more or less closer to your tests.

    Glad you are all enjoying the review!

    I may be a bad one to ask, but I find Cree rings don't bother me at all in real usage. I just don't notice them anywhere but a white wall!

    In terms of degree of rings in beamshots, this often reflects minor focusing difference from one sample to another. If you look at my NDI review, you'll see my pre-production version has much less noticeable rings on the wall beamshot. But in real usage, I can't tell a difference between any of my NDIs.

    The issue with the triangular beam at close quarters is probably more noticeable, but I'll need to play around with more when I get back next week.

    Thanks Viren, I enjoy your reviews as well.

    That's very good battery performance - I presume for an AW protected? I've got 4 AW black-label RCRs (bought at different times), and their performance is all within a minute or two of each other on max drain (e.g. Jet-II IBS). Oddly, I've noticed a lot more variability on my AW 14500 protecteds (some seem to have the same capacity as the RCRs, some are a good 25% or more - one is even 40% longer lasting). So there's definitely some potential for battery variability here.

    All my runtimes are done hot off the charger (TL-100) for all my reviews.

    Great review Selfbuilt! (as always).

    Quick question / request:

    How low is the lowest low? How does it compare to that of the NDI? How about compared to the Lightflux LF2X? Could you post some beamshots comparing the NEx's lowest low with that of the NDI (and maybe a few others - LF2X hopefully?)?

    Thanks,
    -Pete

    This light is really looking tempting. Does anyone know how its total output and throw compare to a SF E1B?

    Hi Pete
    From the first post
    At lower output levels, the Novatac is again the best performer – but the Extreme is still excellent and at least as good as the other regulated competition.
    In terms of absolute lows, unfortunately the Extreme doesn’t go quite as low as the NDI, but it is pretty close to the continuously-variable JetBeam Jet-II IBS.
    Also in the first post, take a look at the Summary chart.
    The second chart has the minimum outputs for all five lights.

    Edit: Hi Selfbuilt,
    On the low test, Was the Novatac 120P at the factory low setting - level 5 (.3 lumens) or did you ramp it down to level 1(.08 lumens)?
    Thanks Steve

    It's all your fault Selfbuit!

    I ordered both Extreme and Jet-II IBS SS head. When they arrive I will compare them with my 120P, NI and Incendio just like your review. The only one is missing in my collection is Fenix: I don't have any Fenix light.

    I just re-read the review. I missed a very important point the first time around. The fact that this light cannot be locked out is a major issue for me. I have forgot to lockout my NDI and had it come on in my pocket. Not pleasant.

    I'm not sure if I can get past this feature missing or not. I believe any pocket rocket like the Extreme should be able to lock out. I can't think of any lights that I have purchased in the last year that don't lock out.

    I will have to give this more thought but a light small enough to be placed in a pocket that you can't lock out doesn't sound right to me. Again I will have to give it more thought.
