    Wink2 Thrunite TN30 Review (3xXM-L, 3x18650): RUNTIMES, VIDEO, OUTDOOR BEAMSHOTS and more!

    Warning: even more pic heavy than usual!




    The TN30 is a new high-output, 3xXM-L, 3x18650 flashlight from Thrunite. Let's see how it compares to other recent lights in this class, including the new TN31 (a high-output singe-emitter "thrower" light based on the same battery handle).

    The production version sent to me came in the full presentation case, with metal hinges and closing flaps. Inside were the light, belt pouch, wrist lanyard, manual, warranty card, and extra o-rings and spare boot cover.

    Note the cut-out foam had a faint acrid smell when the case was first opened, likely due to some sort of outgassing that had built-up inside the sealed case. Leaving it open for a few days allowed it to fully clear up.




    From left to right: AW Protected 18650; Thrunite TN30, TN31, Catapult V3; Xtar S1; 4Sevens S18 Maelstrom; Nitecore TM11.

    All basic dimensions are given with no batteries installed:

    Thrunite TN30: Weight: 468.2g (est 620g with 3x18650), Length: 179mm, Width (bezel): 64.3mm, Width (tailcap): 49.0mm
    Thrunite TN31: Weight: 572.1g (est 723g with 3x18650), Length: 203mm, Width (bezel): 79.0mm, Width (tailcap): 49.0mm
    Xtar S1 Production: Weight: 876.0g (est. 1028g with 3x18650 protected), Length: 240mm, Width (bezel): 83.4mm
    Nitecore TM11: Weight: 342.6g (476g with 8xCR123A), Length 135.3mm, Width (bezel): 59.5mm
    4Sevens S18: Weight: 700g (800g with 6xCR123A), Length: 233mm, Width (bezel) 63.0mm, (tailcap) 25.6mm
    Olight SR51: Weight: 405g, Length: 190mm, Width (bezel) 62.0mm
    Olight SR90: Weight: 1.6 kg (with battery pack), Length: 335mm, Width (bezel): 97mm
    Olight SR92: Weight: 1.15 kg (with battery pack), Length: 271mm, Width (bezel): 98mm

    The TN30 is a substantial light, but it is not as large as some other lights of this class. Probably its closest size comparable is the SR51, which is only a 1xXM-L light.

    Let's start with the case:





    And now the light itself:




    Anodizing is a glossy black, and seems to be good quality – no chips or damage on my sample. Labels were sharp and bright white against the black background. Knurling is fairly aggressive on the handle, helping with grip. Scroll down for a discussion of the control ring feel and use.

    Screw threads are anodized for head lock-out. Threads are standard triangular cut, but seem of good quality.

    Light has a scalloped black aluminum bezel. For more details on the reflector, scroll down to the beamshot section of the review.

    Here are some close-up shots of the control ring:




    There are slight indents on the control ring to help with feel. There is a label mark on the control ring that lines up with the labels on the head. The six constant output modes are not individually labeled, but there is a graded output bar pictogram over the first four levels (i.e., shows the direction to turn to raise or lower the output). There are firm detents at each level, with a slight click as you enter into each one.






    There is a metal battery carrier that holds 3x 18650 cells. The positive contact plate is slightly raised, so all types of 18650 cells should work fine (i.e., true flat-tops, wide and small button-tops). Longer cells may be a bit tight, but my protected 3100mAh cells all fit. The carrier can be inserted either orientation into the handle. Note that particularly wide cells may be a tight fit into the handle.



    The light can tailstand stably, and the tailcap cut-outs facilitate access to the switch. Switch is a forward clicky switch (i.e., press for momentary, click for locked-on). Switch feel is fairly typical, with a definite click. But there's more to it than meets the eye ...



    There is a double set of springs in the base, in addition to the spring in the head. The double-set of springs in the tail is a tip-off that something interesting is going on with the tail-switch and the battery carrier. Here is what the tail switch looks like in detail:




    There is clearly a circuit along with the forward clicky switch. This is presumably to provide some sort of assist to the switch, modifying the load on it. The dual springs is how it draws power from the battery carrier, irrespective of the head. Scroll down to my Standby Drain section for more info.

    User Interface

    Turn the light off/on by the tailcap clicky – press for momentary, press and release (i.e., click) for constant on.

    Change output modes by turning the control ring in the head. Arranged from left-to-right (looking down at the light, held in traditional flashlight carry), the modes are level 1 (moonlight) > level 2 > level 3 > level 4 > level 5 > level 6 (max) > standby > tactical strobe.

    No light is produced on standby, but a miniscule current will be drawn to allow the circuit to respond to a ring turn (see below). As always, I recommend you store the light clicked-off at the tailcap, or locked-out by a head twist.

    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.



    Strobe is an oscillating frequency strobe, switching between 6.9Hz and 14.6Hz on my sample. Each frequency lasts for about 2/3 of a sec. Here is a blow-up of each strobe frequency individually:




    There is a bit of a ramp-up to the peak strobe output, but it is not something you could see in practice. Strobe is quite blazingly fast to the eye.

    Standby Drain

    The "Stand By" mode on the control ring is just that - due to the electronic ring control, the TN30 will always be drawing a small current when the tailcap switch is clicked on.

    I measured this current as 114uA. Since the cells are arranged in series, for 2600mAh 18650s that that would translate into a little over 2.6 years before the cells were fully drained. Note this is slightly higher the 67uA standby current listed in the manual, but that may just be natural variation (e.g., my TN31 was 96uA, in comparison). This is quite reasonable for a standby current.

    There is a secondary circuit in the tailcap that has its own standby drain. You don't often see physical clicky switches in these sorts of high-powered lights, likely due to their inability to handle the typical current flows. In this case, the physical forward clicky is connected to its own circuit that presumably provides some sort of assist to the switch, modifying the load on it.

    I tried to measure the current draw on the tail switch, but my DMM's uA/mA port seems to have gone on the fritz since my earlier measures of the head standby draw were taken. While I'm waiting for a replacement, HKJ reports between 20-50 uA standby drain on the tail switch (scroll down this thread for commentary).

    This means that whenever the battery carrier is loaded with cells and in contact to the tailswitch, a miniscule current will be drawn (i.e., it would take at least 6 years to drain the cells, even at its highest point). But to break this current, you would need to remove the carrier from the handle.

    Beamshots:



    Each emitter was well-centered in its own reflector well – but the wells overlap with each other considerably. Expect a lot of peripheral artifacts in the spill, due to the overlapping wells.

    And now, what you have all been waiting for. All lights are on their respective max battery sources (3xAW protected 18650 for then TN30/31), 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.













    Output is slightly greater initially on the TN30 than most of my other multi-emitter lights. Scroll down for a comparison of estimated lumens.

    Also as expected, the overlapping emitter wells produce visible patterns in the spill. This is particularly noticeable at close-range distances.

    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).



    The TN30 produces a lot more light than the TN31 (1xXM-L), with a wider spillbeam. But it lacks the dedicated throw of the more focused TN31.





    The TN30 has more output than my other 3xXM-L lights (at least initially). Scroll down to my Summary tables for more details on relative output and throw.

    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).



    UPDATE AUGUST 20, 2012: I have revised the summary table above to reflect the results of my new NIST-calibrated lightmeter.

    Initial max output is measurably higher than other 3xXM-L emitter lights I've tested – possibly due to the fact that the 3x18650 cells are in series instead of parallel. You would have to ask a circuit/battery expert to explain this further – but I suspect it has to do with how many amps can be drawn from the cells in series as opposed to parallel.

    Given the estimated output, it seems the TN30 is able to drive the XM-L U2 emitters to their maximum level. Note the output doesn't stay there for long – the light has a step-down after one and half minutes (see my runtimes for more info).

    Peak throw is quite reasonable for the depth of the reflector and the degree of overlap of the wells.

    Lowest output is lower than 1 lumen in my testing. In fact, here is a breakdown of the estimated lumen values for both the TN30 and TN31 in my testing:



    As you can see, the reported output and throw specs from Thrunite seem remarkably consistent with my testing. I suspect Thrunite did indeed get these tested in a properly-calibrated integrating sphere.

    Output/Runtime Comparison:





    Output/runtime performance was quite good for the TN30 when taking into account the 3x18650 battery source. It was certainly well in keeping with other current-controlled lights at these levels.

    Although initially a bit brighter than the other 3xXM-L lights tested here, you will see that the overall runtime pattern is consistent with other lights once step-down occurs (at 69 secs into the run).

    With the exception of the Max output run, the TN30 was quite good at maintaining stably flat regulation across its various modes.

    Although it doesn't show in the runtimes above, the TN30 would flash a few warning flashes shortly before hitting the built-in battery protection circuit shut-down.

    In terms of reported ANSI FL-1 runtimes, the Thrunite numbers seem pretty good, perhaps just slightly inflated at some levels. Remember that my runtimes are done on 2200mAh cells. On 3100mAh cells, I would expect runtimes fairly close to the reported Thrunite specs.



    The above is a comparison of my standard 2200mAh AW cells to the NCR18650A-based 4GREER 3100mAh cells. No real surprises here - the 3100mAh cells perform better.

    Oh, and those little blips near the end of the L6 run on the TN30 are from the low-battery warning system of the light.

    Finally, for those of you have trouble visualizing the conversion of my relative lightbox values to estimated lumens, here is how the TN30 stacks up to the other very high-output lights (note the * ESTIMATED LUMENS * output scale below).



    Potential Issues

    Due to the overlapping reflector design, there are very noticeable artifacts in the periphery of the spillbeam (as with other lights that use a similar design).

    Due to the electronic control ring in the head, the light has a stand-by current when in "Stand By" mode. But this current is very low (96uA), and will not be problem for regular use (i.e. will take about 3 years to drain three fully charged 18650 2600mAh cells). You can break this current by clicking the tailswitch off, or loosening the head from the body.

    However, there is a second standby current due a circuit in the tail to assist the physical switch. The tail circuit draws its power directly from the battery carrier, irrespective to the state of the head (i.e., the purpose of those dual springs in the tail). The current draw is miniscule (i.e., over 6 years to fully drain the cells), but the only way to break it is to remove the battery carrier from the handle.

    Only 3x 18650 Li-ion cells may be used in the light (i.e., doesn't support multiple CR123A primary cells)

    Light uses a battery carrier, and very long or wide cells may be a bit tight. But all cells I tested worked in the carrier, including protected flat-top cells.

    The individual levels are not specifically labeled on the head of the light, so you may need to "count" detents to figure out what level you are set to.

    Preliminary Observations

    The first 3x XM-L high-output light from Thrunite, the TN30 has a lot going for it. It terms of raw power, it is the brightest light of this class I've tested so far (at least for the first 69 secs – after that, it steps down to a level closer to the competition).

    Output/runtime performance was very good, with the current control circuitry providing excellent runtimes at all levels tested. Stabilization was quite good as well, with perfectly flat regulation on all levels, aside from Max output. Note there is a brief warning flash to indicate when the batteries are nearly exhausted.

    In terms of the interface, the control ring worked well in my testing. I particularly liked the clear and firm detents at every level. The six output levels are well spaced (and very accurate to the specs), giving you plenty of output and runtime options. I am also glad to see strobe was placed after a standby mode (i.e., don't need to keep running into it). A good implementation of a control ring.

    I like the use of the physical clicky switch, but its implementation is a little unusual here - there is actually a second circuit in the tailcap that seems to provide some sort of powered assist to it. The standby current draw is tiny though.

    The beam is reasonable for the type and class of light, with plenty of throw and spill. Personally, I am not a fan of the wide overlapping reflector well design, as this produces a lot artifacts, but these are really only noticeable at a close range (i.e., in the near spill).

    The TN30 in an impressive offering. The light performed well in my testing, with little to criticize. I am particularly impressed to see the very accurate output, throw and runtime specs from Thrunite (you would think that ANSI FL-1 would have resulted in more reliable specs overall, but that doesn't generally seem to be the case for many other makers ). Certainly a strong contender in the high-output arena.

    I am very tempted with the TN30 it looks like an excellent alternative to the TM11. It looks like it throws fairly well too

    No, it is not part of my usual testing regimen (external probe placement is a non-trivial matter for accurate comparisons between lights of different size/mass/shape, etc.). My subjective impression is that it doesn't get unreasonably hot, although it may be warmer than some of the competition.

    It's really a different beam pattern, thanks to the TM11's much shallower reflector wells. I would say the TM11 is a more a "wall of light", and the TN30 is between it and the Xtar S1 for throw.

    So from what I understand this light can be used as a signal light with the momentary switch? (As opposed to my non-tactical Quark X AA².)

    Thanks! Looks like the TM11 is getting a run for its (my) money. Two more questions: can the TM11 be used as a signal light in any practical sense, and does the TN30 have any kind of thermal regulation (my Quark has overheated in its holster more than once, and I hear doing that with 18650-based lights can be... unhealthy)?

    The Nitecore TM11 can't really be used for signalling, given how the electronic switch responds to presses.

    As for the thermal regulation on the TN30, I note the specs say that it has "intelligent temperature controlled light output for user safety". What I interpret that to mean is that there is a sensor on the circuit to detect excessive temperature (at what set point I do not know), and a current-limiting feature to respond. I know Thrunite has instituted that on some other recent lights as well. I have not directly tested this, though (and all my runtimes are done under a cooling fan).

    But note that in any case, it is a safety feature to protect the circuit. In a confined space (like the holster, backpack, etc.), you could potentially rise rapidly to temperatures that could do some damage to surrounding material before the circuit-limiting feature kicked in. If you are concerned about accidental activation, you should store the head locked-out when not in use.

    That was quick! Thanks, selfbuilt. With three separate ways to turn the TN30 "off" (lockout, clicky, control ring), I should be pretty safe.
    I think this is going to be the one—unless something even better comes along before I have the cash for it.

    Sorry for bringing up the slightly old thread, but I have a question. I ordered the TN30 and I have plenty of AW IMR 18650 (red)batteries are those good to use in this light? Would you recommend something better?

    The red label AW IMR cells are unprotected, which I don't recommend in multi-battery setups with fully-regulated circuits. IMR chemistry is not required for the current draw in the TN30, and you are definitely safer sticking with protected cells.

    Although you should be able to tell by the reduced output on the L6/L7 modes that it is time to charge those IMR cells, at the lower outputs you are likely to damage the cells by over-discharging before noticing any drop in output. I recommend you pick up any of the quality protected 18650 cells out there - there are tons discussed in the batteries subforum here.

    You should read about batteries in the sub-forum. However the short answer is AW 18650 3100 mAh or the cheaper option Eagletac 18650 3100mAh.

    Thank you for the reply. Was hoping to use the batteries I had but oh well. Thanks for the help, I probably would have killed my IMR's. Is the AW 18650 3100mAh the best you can get for this light in your opinion?

    The 3100mAh Panasonic NCR18650A core is certainly the most popular basis for batteries these days. But there are probably dozens of brands to choose from (each with their own specific protection circuit, etc.). One of those would do fine, but again, check in the battery subforum for discussion of individual brands.

    I can not emember which 18650 works best in the Thrunite TN30, but the protected AW 18650 3100mAh worked exremely well. If I can find the test results, then I will confirm which 18650 performed best in this specific model. It will most likely be by PM, as we may start wondering off topic.

    Sorry should have been more specific. I have read most of the battery reviews. I was trying to look into the amperage draw of the light and make sure the batteries I get can do a more than adequate job. I believe the max amp output for a AW 18650 3100mAh is 5.8A (1.75C approx). Does that light draw more than that on the brightest setting. If there was a Amp draw rating on the light somewhere I apologize for missing it. Once again thanks for helping!

    HKJ determined that the TN30 circuit stabilized at around 3A. So the battery with the best performance at a 3A discharge rate is what you would want. But I don't imagine the difference between most 3100mAh brands at this level is very great -any of them would be fine.

    The production version sent to me came in the full presentation case, with metal hinges and closing flaps. Inside were the light, belt pouch, wrist lanyard, manual, warranty card, and extra o-rings and spare boot cover.

    Note the cut-out foam had a faint acrid smell when the case was first opened, likely due to some sort of outgassing that had built-up inside the sealed case. Leaving it open for a few days allowed it to fully clear up.




    From left to right: AW Protected 18650; Thrunite TN30, TN31, Catapult V3; Xtar S1; 4Sevens S18 Maelstrom; Nitecore TM11.

    All basic dimensions are given with no batteries installed:

    Thrunite TN30: Weight: 468.2g (est 620g with 3x18650), Length: 179mm, Width (bezel): 64.3mm, Width (tailcap): 49.0mm
    Thrunite TN31: Weight: 572.1g (est 723g with 3x18650), Length: 203mm, Width (bezel): 79.0mm, Width (tailcap): 49.0mm
    Xtar S1 Production: Weight: 876.0g (est. 1028g with 3x18650 protected), Length: 240mm, Width (bezel): 83.4mm
    Nitecore TM11: Weight: 342.6g (476g with 8xCR123A), Length 135.3mm, Width (bezel): 59.5mm
    4Sevens S18: Weight: 700g (800g with 6xCR123A), Length: 233mm, Width (bezel) 63.0mm, (tailcap) 25.6mm
    Olight SR51: Weight: 405g, Length: 190mm, Width (bezel) 62.0mm
    Olight SR90: Weight: 1.6 kg (with battery pack), Length: 335mm, Width (bezel): 97mm
    Olight SR92: Weight: 1.15 kg (with battery pack), Length: 271mm, Width (bezel): 98mm

    The TN30 is a substantial light, but it is not as large as some other lights of this class. Probably its closest size comparable is the SR51, which is only a 1xXM-L light.

    Let's start with the case:





    And now the light itself:




    Anodizing is a glossy black, and seems to be good quality – no chips or damage on my sample. Labels were sharp and bright white against the black background. Knurling is fairly aggressive on the handle, helping with grip. Scroll down for a discussion of the control ring feel and use.

    Screw threads are anodized for head lock-out. Threads are standard triangular cut, but seem of good quality.

    Light has a scalloped black aluminum bezel. For more details on the reflector, scroll down to the beamshot section of the review.

    Here are some close-up shots of the control ring:




    There are slight indents on the control ring to help with feel. There is a label mark on the control ring that lines up with the labels on the head. The six constant output modes are not individually labeled, but there is a graded output bar pictogram over the first four levels (i.e., shows the direction to turn to raise or lower the output). There are firm detents at each level, with a slight click as you enter into each one.






    There is a metal battery carrier that holds 3x 18650 cells. The positive contact plate is slightly raised, so all types of 18650 cells should work fine (i.e., true flat-tops, wide and small button-tops). Longer cells may be a bit tight, but my protected 3100mAh cells all fit. The carrier can be inserted either orientation into the handle. Note that particularly wide cells may be a tight fit into the handle.



    The light can tailstand stably, and the tailcap cut-outs facilitate access to the switch. Switch is a forward clicky switch (i.e., press for momentary, click for locked-on). Switch feel is fairly typical, with a definite click. But there's more to it than meets the eye ...



    There is a double set of springs in the base, in addition to the spring in the head. The double-set of springs in the tail is a tip-off that something interesting is going on with the tail-switch and the battery carrier. Here is what the tail switch looks like in detail:




    There is clearly a circuit along with the forward clicky switch. This is presumably to provide some sort of assist to the switch, modifying the load on it. The dual springs is how it draws power from the battery carrier, irrespective of the head. Scroll down to my Standby Drain section for more info.

    User Interface

    Turn the light off/on by the tailcap clicky – press for momentary, press and release (i.e., click) for constant on.

    Change output modes by turning the control ring in the head. Arranged from left-to-right (looking down at the light, held in traditional flashlight carry), the modes are level 1 (moonlight) > level 2 > level 3 > level 4 > level 5 > level 6 (max) > standby > tactical strobe.

    No light is produced on standby, but a miniscule current will be drawn to allow the circuit to respond to a ring turn (see below). As always, I recommend you store the light clicked-off at the tailcap, or locked-out by a head twist.

    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.



    Strobe is an oscillating frequency strobe, switching between 6.9Hz and 14.6Hz on my sample. Each frequency lasts for about 2/3 of a sec. Here is a blow-up of each strobe frequency individually:




    There is a bit of a ramp-up to the peak strobe output, but it is not something you could see in practice. Strobe is quite blazingly fast to the eye.

    Standby Drain

    The "Stand By" mode on the control ring is just that - due to the electronic ring control, the TN30 will always be drawing a small current when the tailcap switch is clicked on.

    I measured this current as 114uA. Since the cells are arranged in series, for 2600mAh 18650s that that would translate into a little over 2.6 years before the cells were fully drained. Note this is slightly higher the 67uA standby current listed in the manual, but that may just be natural variation (e.g., my TN31 was 96uA, in comparison). This is quite reasonable for a standby current.

    There is a secondary circuit in the tailcap that has its own standby drain. You don't often see physical clicky switches in these sorts of high-powered lights, likely due to their inability to handle the typical current flows. In this case, the physical forward clicky is connected to its own circuit that presumably provides some sort of assist to the switch, modifying the load on it.

    I tried to measure the current draw on the tail switch, but my DMM's uA/mA port seems to have gone on the fritz since my earlier measures of the head standby draw were taken. While I'm waiting for a replacement, HKJ reports between 20-50 uA standby drain on the tail switch (scroll down this thread for commentary).

    This means that whenever the battery carrier is loaded with cells and in contact to the tailswitch, a miniscule current will be drawn (i.e., it would take at least 6 years to drain the cells, even at its highest point). But to break this current, you would need to remove the carrier from the handle.

    Beamshots:



    Each emitter was well-centered in its own reflector well – but the wells overlap with each other considerably. Expect a lot of peripheral artifacts in the spill, due to the overlapping wells.

    And now, what you have all been waiting for. All lights are on their respective max battery sources (3xAW protected 18650 for then TN30/31), 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.













    Output is slightly greater initially on the TN30 than most of my other multi-emitter lights. Scroll down for a comparison of estimated lumens.

    Also as expected, the overlapping emitter wells produce visible patterns in the spill. This is particularly noticeable at close-range distances.

    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).



    The TN30 produces a lot more light than the TN31 (1xXM-L), with a wider spillbeam. But it lacks the dedicated throw of the more focused TN31.





    The TN30 has more output than my other 3xXM-L lights (at least initially). Scroll down to my Summary tables for more details on relative output and throw.

    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).



    UPDATE AUGUST 20, 2012: I have revised the summary table above to reflect the results of my new NIST-calibrated lightmeter.

    Initial max output is measurably higher than other 3xXM-L emitter lights I've tested – possibly due to the fact that the 3x18650 cells are in series instead of parallel. You would have to ask a circuit/battery expert to explain this further – but I suspect it has to do with how many amps can be drawn from the cells in series as opposed to parallel.

    Given the estimated output, it seems the TN30 is able to drive the XM-L U2 emitters to their maximum level. Note the output doesn't stay there for long – the light has a step-down after one and half minutes (see my runtimes for more info).

    Peak throw is quite reasonable for the depth of the reflector and the degree of overlap of the wells.

    Lowest output is lower than 1 lumen in my testing. In fact, here is a breakdown of the estimated lumen values for both the TN30 and TN31 in my testing:



    As you can see, the reported output and throw specs from Thrunite seem remarkably consistent with my testing. I suspect Thrunite did indeed get these tested in a properly-calibrated integrating sphere.

    Output/Runtime Comparison:





    Output/runtime performance was quite good for the TN30 when taking into account the 3x18650 battery source. It was certainly well in keeping with other current-controlled lights at these levels.

    Although initially a bit brighter than the other 3xXM-L lights tested here, you will see that the overall runtime pattern is consistent with other lights once step-down occurs (at 69 secs into the run).

    With the exception of the Max output run, the TN30 was quite good at maintaining stably flat regulation across its various modes.

    Although it doesn't show in the runtimes above, the TN30 would flash a few warning flashes shortly before hitting the built-in battery protection circuit shut-down.

    In terms of reported ANSI FL-1 runtimes, the Thrunite numbers seem pretty good, perhaps just slightly inflated at some levels. Remember that my runtimes are done on 2200mAh cells. On 3100mAh cells, I would expect runtimes fairly close to the reported Thrunite specs.



    The above is a comparison of my standard 2200mAh AW cells to the NCR18650A-based 4GREER 3100mAh cells. No real surprises here - the 3100mAh cells perform better.

    Oh, and those little blips near the end of the L6 run on the TN30 are from the low-battery warning system of the light.

    Finally, for those of you have trouble visualizing the conversion of my relative lightbox values to estimated lumens, here is how the TN30 stacks up to the other very high-output lights (note the * ESTIMATED LUMENS * output scale below).



    Potential Issues

    Due to the overlapping reflector design, there are very noticeable artifacts in the periphery of the spillbeam (as with other lights that use a similar design).

    Due to the electronic control ring in the head, the light has a stand-by current when in "Stand By" mode. But this current is very low (96uA), and will not be problem for regular use (i.e. will take about 3 years to drain three fully charged 18650 2600mAh cells). You can break this current by clicking the tailswitch off, or loosening the head from the body.

    However, there is a second standby current due a circuit in the tail to assist the physical switch. The tail circuit draws its power directly from the battery carrier, irrespective to the state of the head (i.e., the purpose of those dual springs in the tail). The current draw is miniscule (i.e., over 6 years to fully drain the cells), but the only way to break it is to remove the battery carrier from the handle.

    Only 3x 18650 Li-ion cells may be used in the light (i.e., doesn't support multiple CR123A primary cells)

    Light uses a battery carrier, and very long or wide cells may be a bit tight. But all cells I tested worked in the carrier, including protected flat-top cells.

    The individual levels are not specifically labeled on the head of the light, so you may need to "count" detents to figure out what level you are set to.

    Preliminary Observations

    The first 3x XM-L high-output light from Thrunite, the TN30 has a lot going for it. It terms of raw power, it is the brightest light of this class I've tested so far (at least for the first 69 secs – after that, it steps down to a level closer to the competition).

    Output/runtime performance was very good, with the current control circuitry providing excellent runtimes at all levels tested. Stabilization was quite good as well, with perfectly flat regulation on all levels, aside from Max output. Note there is a brief warning flash to indicate when the batteries are nearly exhausted.

    In terms of the interface, the control ring worked well in my testing. I particularly liked the clear and firm detents at every level. The six output levels are well spaced (and very accurate to the specs), giving you plenty of output and runtime options. I am also glad to see strobe was placed after a standby mode (i.e., don't need to keep running into it). A good implementation of a control ring.

    I like the use of the physical clicky switch, but its implementation is a little unusual here - there is actually a second circuit in the tailcap that seems to provide some sort of powered assist to it. The standby current draw is tiny though.

    The beam is reasonable for the type and class of light, with plenty of throw and spill. Personally, I am not a fan of the wide overlapping reflector well design, as this produces a lot artifacts, but these are really only noticeable at a close range (i.e., in the near spill).

    The TN30 in an impressive offering. The light performed well in my testing, with little to criticize. I am particularly impressed to see the very accurate output, throw and runtime specs from Thrunite (you would think that ANSI FL-1 would have resulted in more reliable specs overall, but that doesn't generally seem to be the case for many other makers ). Certainly a strong contender in the high-output arena.

    TN30 provided by Thrunite for review.

    Selfbuilt,

    Great review, I purchased a TN30 last week, partly on your recommendation. I do have one question, on highest setting ( #6) there is a "ramp up" to full intensity and it honestly seems that setting 6 is not much brighter than #5. As the difference is over 1000 lumens, I would think it would be more noticeable. Was your test unit like that?

    Thanks

    I've heard this from other owners, too, so your TN30 is most probably fine.
    Have you seen turbobb's review with beamshots at the different brightness settings? The brightness steps seem to be more or less evenly spaced, #6 being brighter than #5, but not a lot. (Bear in mind the logarithmic relationship between physical luminance and subjectively perceived brightness.)

    Yes, the ramp up feature is on mine too. It was mentioned in the reviews as well.
