Thread: Nitecore TM15 (3xXM-L U2, 4x18650, 8xCR123A/RCR) Review: RUNTIME, BEAMSHOTS, VIDEO +

  1. #1

    Thumbs up Nitecore TM15 (3xXM-L U2, 4x18650, 8xCR123A/RCR) Review: RUNTIME, BEAMSHOTS, VIDEO +

    Warning: pic heavy, as usual.




    The TM15 is a latest member of the ‘Tiny Monster’ series from Nitecore. It is a high-output, 3xXM-L, 4x18650 (8xCR123A/RCR) light with a built-in recharging dock for 18650. Let's see how it compares to other recent lights in this class that I've reviewed recently ….

    Packaging is a cardboard box with built-in packaging foam. Inside you will find the light, belt holster, extra o-ring, simple wrist lanyard (with threading wire), manual and AC charging cable. My sample came with the standard North American 110V AC charging plug.




    From left to right: AW Protected 18650; Nitecore TM15, TM11; Sunwayman T60CS; Thrunite TN30.

    All dimensions are directly measured, and given with no batteries installed:

    Nitecore TM15: Weight: 450.6g (634g with 4x18650). Length 158mm, Width (bezel): 59.5mm
    Nitecore TM11: Weight: 342.6g (526g with 8xCR123A), Length 135.3mm, Width (bezel): 59.5mm
    Sunwayman T60CS: Weight: 338.9g (est 477g with 3x18650), Length: 145.0mm, Width (bezel): 60.0mm
    Thrunite TN30: Weight: 468.2g (est 620g with 3x18650), Length: 179mm, Width (bezel): 64.3mm, Width (tailcap): 49.0mm
    Xtar S1 Production: Weight: 876.0g (est. 1028g with 3x18650 protected), Length: 240mm, Width (bezel): 83.4mm
    Olight SR51: Weight: 405g, Length: 190mm, Width (bezel) 62.0mm

    The TM15 is definitely a longer light than the TM11, but otherwise looks very similar in build. In fact, the battery handle appears to be virtually identical – the difference is all in the head.





    As with the TM11, anodizing is a flat black, and seems in excellent shape on my sample. There is some knurling on the head and body, of reasonable aggressiveness. Overall grip is certainly decent, despite the cylindrical shape.

    Body labels are rather extensive as before – in additional to the usual maker and model information, you also have a 5-point series of warnings about the light (in a very tiny, but legible, font). The light can tailstand.

    Battery handle is quite compact, and easily houses 4x18650 or 8xCR123A/RCR. The battery compartments are molded right into the aluminum, with a common negative terminal contact plate. You don't need to fill all the wells for the light to work, but should expect lower runtime (and Turbo mode is not recommended on anything but the full complement of cells). Again, scroll down for more info.

    As before, screw threads are anodized for lock-out.

    Inside the head, there are two raised contact rings for the positive and negative current paths. These appear the same as the TM11, and are quite solid (likely gold-plated brass?).

    The switch design has changed a little bit from the TM11. It is still a two-stage (two-pressure) electronic switch, but the button projects out a little further now. The ring around the switch now uses a blue LED instead of red to signal the state of the light (i.e., battery status, voltage, and standby modes). Scroll down for an explanation of the interface.




    The TM15 has an AC charging cable that connects on the back of the head. The connection point has a small rubber cover, held down with a screw. Not sure how durable or water resistant this will be long-term. Note the charging solution is to be used ONLY with 18650 cells.

    Nitecore estimates it will take about 7 hours to full charge the cells this way, which seems a reasonable estimate (i.e., it took just over 6 hours for my relatively low capacity 2200mAh 18650 cells). My somewhat used cells all came out ~4.14-4.15V in my testing, which is a nice conservative level (i.e., just ~0.01-0.02V less than my Pila charger on these same cells).

    There is also a tripod attachment mount nearby, with uses the standard tripod screw diameter (presumably 1/4-20 UNC). Note that I found some of inexpensive tripod mounts were a bit loose when screwing into the TM15 (e.g., gorilla-pods), but seemed stable enough in the end. Professional tripods mounts fit stably and securely. The mount seems a little far forward on the light, given that a lot of the weight is in the battery handle.




    TM15 has the same size bezel opening as before, and comes with a stainless steel bezel ring, slightly scalloped. The screw-on bezel diffuser from the Eagletac M2- and M3- series lights works as before.

    The TM15 uses 3x cool white XM-L emitters as before. However, the TM15 has much deeper reflector wells than the TM11, as illustrated below:

    TM11 on the left, TM15 on the right:


    Scroll down for beam pic comparisons.

    User Interface

    The TM15 uses an updated version of the TM11’s innovative two-stage electronic switch.

    Like before, for Turbo output, press the switch all the way and release (for constant on), or press firmly and hold for momentary on. What's new is that this "Turbo" set also has a slightly lower Hi mode, which you can switch to and from (when locked on in Turbo) by half-pressing the switch and releasing. There is no mode memory on this mode set – the light always comes on in Turbo. Turn off by a full press and release.

    For the lower "Daily" modes, only partially press the switch from off (again, hold for momentary, release quickly for locked-on). Light will come on in the memorized lower output mode. As described above, to switch modes when on, simply half-press and quickly release the switch again. The light will advance to the next output, in repeating sequence of Lower > Lo > Med > Hi. The light has memory on this mode set, and will retain the last lower output used. Turn off by a full press and release.

    Along with the raised switch, the pressure required to activate the various modes has changed slightly from the TM11, but you quickly get used to it.

    The light will read-out the voltage of the cells when you first connect the head, by a series of blue flashes around the on-off switch. After the initial voltage read-out, the light will then flash once every three seconds (when off), to let you know you are in standby mode. The indicator stays constantly illuminated when the light is on. It will start to flash as the batteries begin to drain, at increasing frequency.

    A "hidden" strobe mode can be accessed by two rapid full presses of the switch from On. Turn off or double-click again to return to constant output modes.

    There is a switch lock-out mode that prevents accidental activation (and lowers the standby current, see below). Press the switch all the way down and hold for more than one second. When you release, the light will turn off and enter the lockout mode. To exit the lockout mode, simply press and hold the switch firmly for more than one second.

    The charger plugs in under the rubber cover on the back of the head. The blue indicator light comes on during charging, flashing twice a second. Once the charge is complete, the indicator shows solid blue. My sample charged to a reasonably full level.

    For information on the light, including the build and user interface, please see my new video overview:



    As always, videos were recorded in 720p, but YouTube typically defaults to 360p. Once the video is running, you can click on the configuration settings icon and select the higher 480p to 720p options. You can also run full-screen.

    PWM/Strobe

    There is no sign of PWM on any level – I believe the light is current-controlled, as expected.



    As you can see above, the TM15 has a true variable frequency strobe. In my testing, the time between pulses varied from ~75 to ~200 msecs (or 5 to 13 Hz).

    Standby Drain

    Due to the electronic switch, the TM15 will always be drawing a small current when the body/carrier is connected to the head. I measured this current as 790uA (although it would periodically spike every couple of seconds to ~3.6mA for a fraction of a second, when the signal flash occured).

    Going with an "average" current of ~1mA, and assuming four times 2600mAh capacity batteries, that would give you a little over 1 year and 2 months before four fully charged batteries would be completely drained (given the parallel cell arrangement). This is about twice the current of my TM11, but it's certainly not bad.

    Note there is always an electronic lock-out mode, to lock-out the switch and reduce the standby current. I don't know how much this lowers the current, but it likely to be significant. You can also break this current completely by turning the head a quarter turn (due to the anodized threads).

    Beamshots:

    And now, what you have all been waiting for. All lights are on their respective max rechargeable battery sources (i.e., 18650s), about ~0.75 meter from a white wall (with the camera ~1.25 meters back from the wall). Automatic white balance on the camera, to minimize tint differences.













    The TM15 clearly has a much narrower spillbeam than the TM11, due to the deeper reflectors. In fact, both overall output and throw have increased on the TM15, compared to the earlier TM11.

    Despite how it may look above, there is no artifact near the hotspot on my TM15 (rather, that faint line seems to be a mark on my white wall ).

    In my experience, these sorts of deep well 3xXM-L lights tend to have a lot of "daisy flower" artifact effects in the spillbeam. But the TM15's reflector design is remarkably good – I see very little evidence of artifacts in this case. Much better than most lights in this class.

    To show the spill a little better, here are some side shots on my famed "integrating carpet".





    Again, the TM15 is far more focused for throw than most other 3xXM-L lights.

    For outdoor beamshots, these are done in the style of my earlier 100-yard round-up review. Please see that thread for a discussion of the topography (i.e. the road dips in the distance, to better show you the corona in the mid-ground). Please ignore the red-tint in the lower-right corner these shots (I was wearing a brighter-than-usual red headlamp during this excursion ). Zoomed-in pics of the hotspots are also included.




    Here is how the TM15 compares directly to the TM11:




    I know it can be a bit hard to compare, given the slight variation in angling of the lights and the tint differences. But as you can probably tell, the TM15 is a greater thrower than the TM11. The TM15 is generally comparable in throw to the Thrunite TN30.

    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 any extended run Lo/Min modes (i.e. >12 hours) which are done without cooling.

    I have devised a method for converting my lightbox relative output values (ROV) to estimated Lumens. See my How to convert Selfbuilt's Lightbox values to Lumens thread for more info.

    Throw/Output Summary Chart:

    My summary tables are reported in a manner consistent with the ANSI FL-1 standard for flashlight testing. Please see http://www.flashlightreviews.ca/FL1.htm for a discussion, and a description of all the terms used in these tables. Effective July 2012, I have updated all my Peak Intensity/Beam Distance measures with a NIST-certified Extech EA31 lightmeter (orange highlights).



    Turbo output is quite high – similar to my other recent 3xXM-L lights (i.e., the Sunwayman T60CS and Thrunite TN30). Throw is higher on my sample than the Nitecore specs indicate.

    Here is how the TM15 compares to the TM11 in terms of relative level spacing.



    Nitecore's lumen specs seem to be pretty accurate.

    Output/Runtime Comparison:

    Note: All my 18650 runtimes are done using AW protected 2200mAh.




    The TM15 shows excellent efficiency for this class, in keeping with the current-controlled circuit. Output is flat-regulated at all levels, very similar to the TM11.



    There was a step-down from Turbo to Hi on 8xCR123A after ~20 mins runtime. I suspect this was the thermal sensor kicking in to limit output. Note that primary CR123As tend to get a lot hotter than 18650 under high drive currents, which may be why I didn't observe any step-down effects on the 18650 runs (all runs above done under a cooling fan, as always).

    As you will recall from my earlier TM11 review, there was some variability initially in the thermal sensitivity of the step-down control circuit of that model, even on 18650 (i.e. that light always stepped down eventually, even with cooling). I'm guessing the larger head of the TM15 has also allowed from improved heatsinking.

    Since most of you are not likely to be running your lights under a cooling fan, I did an analysis of what happens if you run the light without any cooling whatsoever, on 4x18650. I also attached a thermal probe on the surface of the head of the light, just above the switch.



    As you can see above, the rise in temperature triggered a step-down from Turbo to Hi on 18650 after about ~20 mins of runtime. The surface of the light was definitely quite warm by this period, but cooled down quickly once the output stepped down.

    With 4x18650, the output remained stably at this Hi level for the rest of the run. This is in contrast to the gradual partial recovery of output on 8xCR123A as the temperature dropped, but that may reflect differences in the internal resistance of the different chemistries. I am happy to report there is no sign of the rapid cycling in output I observed on the early TM11 samples.

    In case you are curious, here is how the TM15 compares to other lights in estimated lumens:



    Potential Issues

    Due to the overlapping reflector design, there are bound to be some artifacts in the periphery of the spillbeam. However, I find them to be surprisingly minor in this case. The light is a lot "throwier" than the TM11 (by design), with a much narrower spillbeam.

    Due to the electronic switch in the head, the light has a stand-by current when waiting to receive a button press. This current is reasonably low (~1mA, on average). You can lower this standby current further by locking out the switch. You can also completely break this current by loosening the head from the body.

    The charging dock cover feels a little flimsy, but has held in fine during my testing so far. Note the charger is meant only for 18650 cells - do not attempt to charge other kinds of batteries inside the light.

    The raised switch - and increased sensitivity - may result in greater accidental activations on the TM15, compared to the earlier TM11. I do find the new sensitivity easier to use in practice, though.

    Preliminary Observations

    The TM15 is an impressive update to the Tiny Monster series of Nitecore lights. As many of you may recall, there were a number of initial circuit and soldering issues at the time of the TM11 launch. Nitecore seems to have these now well in hand, judging by my one TM15 sample – it performed consistently and reliably throughout my testing.

    There are some minor circuit and user interface tweaks from the earlier TM11, as described earlier in this review. These are relatively minor, although I personally prefer the new raised switch and feel. I am glad to see they have kept the standby current to an acceptably low level, and have provided a variety of lock-out options.

    Overall output/runtime efficiency and regulation pattern remain excellent. The thermal sensor-driven step-down on Turbo worked exactly as I would have expected, with a reasonable set point and sensitivity (i.e., there was none of the repeated "cycling" pattern I observed on the early TM11 samples).

    The build is very similar to the TM11, and continues to feel solid and robust. As before, those with smaller hands may find it a bit awkward to carry for extended periods. It is also heavier now, thanks to the greater heatsink and deeper reflector wells.

    On that point, I am impressed with the quality of the beam. The TM15 is much "throwier" than the TM11, but without the usual heavy spill artifacts I've noticed on previous on 3xXM-L designs. Clearly, a lot of work went into this reflector.

    As before, the light has considerable battery flexibility by running the four wells in parallel. You can thus run the light in 1x, 2x, 3x, or 4x 18650 configurations (or 2x, 4x, 6x, 8x CR123A/RCR). Although I haven't tested it here, I recommend you don't try to run Turbo on anything less than the full 4x/8x complement of cells (or Hi on anything less than 3x/6x). Although in a pinch, I'm sure you could get by with an IMR-18650 or two (if you had ones that were long enough to activate the light).

    The other new addition here is the built-in battery charger option. My testing showed this charger worked as expected, with a nice conservative termination level (i.e., didn't over-charge my cells). I can't easily determine if it terminates completely at the end of a charge, but Nitecore assures me that it is "intelligent automatic" like their i4 charger, and will terminate charging immediately. Note that the i4 charger actually has a low uA current once charging is complete, but it is so low as to be close enough to full termination (i.e., it is definitely not a trickle charge). If it is the same here, then there is nothing to worry about.

    All told, the TM15 is a nice addition to the Tiny Monster line. The circuit tweaks are really more evolutionary than revolutionary, and the built-in charger worked well in my testing. But to me, the main advantage of this light over the TM11 is the much greater throw.

    I did contact Nitecore about the cover for the charging port and they replied: "As to the charging cover, is it necessary to prepare a spare
    one? For example, I don't see mobile phones prepare spare covers.
    "

    I have two TM11's Version 3 and I have one of the TM15 too.

    This is a good step in this light's development and NITECORE wrote they plan on continuing making the TM11.

    My (waterproof) Xperia Active actually did come with a spare back cover, which I thought was a very nice touch. The second cover was white, as opposed to the preinstalled black cover.



    And thanks for another epic review, selfbuilt!

    I agree with your comment; I have both the TM11 & TM15 and I am pleased that NITECORE will still make the TM11.

    The TM15 has an advantage of a lower out put, but it extra size makes the TM11 a first choice.

    Fully loaded the difference is nearly 6 ounces. (Might be more or less with 4x18650 in the TM11)

    TM15: 634g with 4x18650).
    TM11: 476g with 8xCR123A
    158g (5.57oz)

    4 18650's @3100mAh weigh more 8 Surefire.

    Default Re: Nitecore TM15 (3xXM-L U2, 4x18650, 8xCR123A/RCR) Review: RUNTIME, BEAMSHOTS, VIDE

    You're right:

    TM15: 634g with 4x18650).
    TM11: 476g with 8xCR123A
    158g (5.57oz
    )


    4x18650: 186.4g (3100mah Redilast)
    8xcr123: 132.8g (Duracell)
    53.6g

    TM11: 344.8g without batteries (slightly more than Selfbuilt's figure)
    +186.4g

    530.2g Total with 4x1850 3100's

    TM15: 634g with 4x18650
    TM11: 530g with 4x18650

    104g (3.7oz)

    So, with 4x18650's in each light, the TM15 is 104g/3.7oz heavier than the TM11. This is still a noticeable but not unduly burdensome difference. (Selfbuilt's 2200 Mah 18650s will be lighter than the 3100s, but I don't have any 2200's available
    for weighing)

    Pretty close - I just went and measured to confirm, and my TM11 comes up as 526g with 4x18650 AW 2200mAh installed. As you would expect - the TM15 base unit is 108g heavier than the TM11. I've updated the review with the weight, to allow you to directly compare to other lights measured with the same AW 2200mAh cells.

    Presumably that is part of it - but Nitecore has taken advantage of the opportunity to extend the reflector depth. It seems a reasonable size, all things considered.

    On a side note, the button now is much more sensitive than the TM11 meaning accidental presses are easy with the holster or in general. Do you see the same thing on the copy supplied to you Selfbuilt?

    Very good review. Thanks.
    TM15 is a very goog light, but Fenix Tk75 on paper seems a lot better, and US100 cheaper.

    Not bad, just the size, and the D Battery really...If I were Arnold Schwarzenegger, I would buy for sure... Too big to handle it...

    What D battery? It's not the TK70.

    Excellent review. Selfbuilt! Thanks a lot for your time & effort as always.

    It's certain that TM15 is upgraded light of the TM11. The light shows a better regulation stably in temperature.

    By the way, I'd like to know the test room temperature, the point on the light where the thermal probe were set in pace in detail, and whether you open the window during the test or not.

    Do the LEDs in your unit glow in pitch dark with the light off and on standby? Some reports of this, and my TM 15 does it. The glow is even across all three LEDs, no flicker.

    Interested in NiteCore's response to this; unsure if it is a bug.

    Is this to be a concern? I wouldn't imagine it doing much in the way of battery consumption. I just ordered a TK15 so I'm curious.

    BTW, new here and long time lerker. Tons of great info here. Thank you very much to the OP for the review. Its one of the reasons I ordered the TK15.

    I ordered the T15e even though I have the excellent Thrunite TN30 which appears to have a slightly longer throw The appeal over the TN30 is a shorter body and longer runtime.

    I haven't tried carrying it in the case, but I can believe it would be more likely to come on accidentally (as it protrudes more now). I like the increased sensitivity for handling (i.e. just a light touch for Daily modes now, before on the TM11 I tended to press too hard and get Turbo inadvertently). But it's true this could be an issue.

    Room temp was about 21 degrees C, the surface probe read 24 degrees C at start. Probe placement was just above the switch, but below the fins (i.e., the same as my TM11 review). There is no open window, and my lightbox is in a cramped corner of my room (i.e., no airflow without a fan).

    No signs of that on mine. I would definitely consider that a bug, and would request a RMA if mine did it.

    The difference in throw between the TM15 and TN30 is not significant. I personally prefer the TM15 beam pattern as it is "prettier", with less artifacts (e.g., look at the 1/100sec white wall shots of the two lights). Overall spillbeam width is narrower on the TM15, though.

    Hello Bwolcott,

    We don't think it can be regarded as a bug.

    After receiving feedback, we checked our stock immediately and found it true that there is a small quantity of TM15 have the glow situation. From then on, we strengthened our QC in this aspect. At the same time our Research and Inspection departments immediately looked into the situation, and found that the glow result from one component, as some units from that batch of component is not funtioning stably. But it would not influence the performence and duration of TM15.

    We are sorry to cause inconvinience to those customers who got a glow light, and would be very pleased to make replacement to them if they need. For more information about TM15, customers can write to our service email box, and we will reply in a prompt way. service@nitecore.com

    Here we would like to say "thank you" to all the buddies showing their supports and attention on NITECORE, and wish you all can continuously keep your attention on NITECORE flashlights.

    Skelt11,

    No worries. Please contact our local dealer for a new replacement.

    And we promise that, the glow will not influence the performence and duration of TM15.

    Yep, I think I mixed up with TK75, u r right, 4*18650 for TK70, then it's more obvious TM15's size is... u know TM15 also use 4*18650 even has the rechargeable function...That's the kind I'm looking for, small size but powerful...Save $...

    Honestly I dont know what to think of your QC department, Inspection department, Research department, however you call it.
    Is it true that Sysmax released 3 different versions (also called improved, corrected official hardware revisions or reiterations) of the predecessor product TM11? I got no problem with that. Zebralight does it all the time too, and Nitecore did the same thing with

    • Sysmax Intellicharge i4 V1 => Nitecore Intellicharger i4 V2
    • Nitecore D11 => Nitecore D11.2
    • Nitecore EX11 => Nitecore EX11.2
    • Nitecore TM11 V1 => TM11 V2 => TM11 V3 (exact version number called: v1.12-1111)



    So i am wondering if there will be updated i.e. improved/corrected/official hardware revisions of the TM15, too, in future

    Well, we dont know this kind of info for sure at this early point in time, right? And the integrated charger charges only up to 4.14-4.15V, what's up with that? The Intellicharge i4 V2 charges to 4.20V, exactly. That's perfect and exact. The TM15's integrated charger doesnt work as perfect and exact, seems like!

    That sounds great, thanks! There is no hurry, is there? According to the NITECORE Warranty Terms, users who got a glow light have 18 months time to send in the light under a warranty claim and ask for a replacement, am i right?

    (Btw, sorry for giving you a hard time.. but you're on the line here so. )
