    Arrow [Review] Nitecore TM10K ... 10,000 lm!! + 3-button UI + QC2.0 USB!

    At “10,000 Lumens!!,” this is Nitecore’s new lumen king and it can totally fit in your pocket!

    Link to manufacture product page: https://flashlight.nitecore.com/product/tm10k
    Overview

    The light has it all, wall of light, small form factor, 3-button UI, user-adjustable HIGH mode, OLED screen, USB QuickCharge2.0, bigger lanyard hole and a built in pocket clip! Some laugh at the 7 second TURBO, and all I can say is that it could of been 3.5 seconds.
    Quick Specs



    Included

    • TM10K (with built-in battery)
    • Holster
    • USB C to USB A cable (USB 2.0)
    • Lanyard
    • Little string? (probably for fishing the lanyard through holes)
    • Manual
    • Warranty card






    Options

    This is the only option.
    Price

    Current price is about $300
    Look & Feel

    Outside

    Overall, the body is very small, has a square cut pattern, and nicely-rounded corners. The body could do with a little more knurling especially on the side with the Nitecore decal. The metal switches are very flush with the body but other design elements help to find the switches. The USB C cover is easy to open but difficult to close up. The front lens seam has a little leftover glue or debris.













    Inside

    The light has a built-in battery and I did not attempt to disassemble the light.
    Accessories

    As stated before, the package comes with a holster, pocket clip, lanyard, USB cable, and a little string? I’m not sure if the string usually comes with it but it may be used for attaching a lanyard.








    Optics

    LED specs

    The light uses six XHP35 HD LEDs made by CREE.

    Beam Profile

    The light has a 26 degree FWHM beam angle; either way you hold the light. This is the angle at which light output has reached 50% of maximum.
    With a high-output light like this, 1% of output (100 lumen) is very usable light, therefore you could consider the total spill beam angle to be almost 120 degrees.
    Currently, these readings are strictly sensor recorded, and are not adjusted based on human perception of light.
    On Ultra Low, the light actually only lights up the inner 2 leds, pretty cool idea.







    Tint

    TM10K, like most of the other XHP35 HD lights, has a yellow spot with cooler spill. On the right is a more neutral Nichia 219B in the Nitecore MT06MD penlight.

    Output Levels

    The default spacing is geared towards every-day closer up use, since the HIGH stops at 1,000 lumens by default. Luckily you can set the high from anywhere from 400 lumens up to 2,000 lumens; I would have liked to been able to set the high to 5,000 lumens though.







    Outdoor Beamshots

    All the pictures below are taken with the light in TURBO.







    Power

    Battery

    The light has a built-in, non-serviceable, 4,800 mAh battery. Usually the reason for this is for increased performance but also helps reduce the body length.
    Indicators

    Like the other TMs, this has a built-in OLED screen which provides feedback on the light, including: current mode with lumens, light temperature, battery voltage, battery status icon, charging mode feedback, lock and unlock, and a discharge bar for the TURBO. If the light has gotten too hot, the display will say “Overheat” and you are locked out of TURBO until the light cools.
    Additionally, there is a blue indicator light on the TURBO button for button finding, and for a drop and find type mode. If memory serves me, I believe this blinks rapidly during overheat and when the battery gets very low.











    Charging

    It took me about 2h 30m to fully charge the light which is a bit longer than the 1.5 hours stated in the manual; according to my data, the 1.5 hours is to get to 80% full mark which is kind of what the marketing for QC emphasizes that you get pretty full fast but takes a while to finish it off. For some reason, some of the marketing material on the website says “Approx. 30 min to charge most of battery” but according to my data, 30 min gets to only about 34% full.


    The light uses USB-C but does not provide a wall adapter which is needed for the QuickCharge function. I used a QC2.0 source and the power supply jumped up to 12V at 1.5A. See table below for the QC2.0 voltage/current combos.
    Technology Voltage Max Current Max power
    Quick Charge 1.0 5 V 2 A 10 W
    Quick Charge 2.0 5 V, 9 V, 12 V 3 A, 2 A, or 1.67 A 18 W (9 V * 2 A)
    I typically verify battery capacity by summing up all the current and converting the time to hours but it appears the light is using a switching circuit to increase the amperage so I can’t directly measure the direct supply to the cell. I summed the watts over time separately and I got about 22Wh and if it’s the same as this cell (https://charger.nitecore.com/product/inr21700) with about 17Wh, than the light has a pretty conservative cell.

    Performance

    Runtimes

    As advertised the TURBO is limited to 7 seconds which seems mainly for heat management purposes. Since the HIGH mode can be adjusted to 2,000 lumens I ran the light at that level.

    PWM Check

    There appears to be no significant PWM on any constant mode.For comparison, the third graph shows PWM varying from 0 to 120 lx on the LOW mode on the Nitecore R25 flashlight.




    Strobe/Beacon

    There is no strobe or any special modes.
    User interface

    The UI is well done and this 3-button interface I believe is a new one for Nitecore. Very happy to see shortcuts to Ultra Low and to High. It even has the boost UI that allows you to have a momentary TURBO by holding the mode button from ON.
    There are two electronic lockout modes, Lockout #1 leaves on the TURBO switch, and Lockout #2 locks all switches. I think that the Lockout #1 should be opposite, lock out the TURBO switch, or TURBO mode altogether, and leave on the side switches.
    A little surprising that there is no strobe or other special modes but this helps open up a lot of options on the UI.
    There is a little beacon mode initiated from OFF by pressing both POWER and MODE switches together until the screen says BEACON ON, and the TURBO switch indicator will blink blue repeatedly when the light is off, and will persist if the light is turn on and off again.

    Conclusions

    Highlights

    • Huge output in a small body
    • Lots of UI options but still easy to get to basics
    • OLED screen tells you temperature and cell voltage, etc
    • Configurable HIGH
    • QC2.0 charging

    Comments

    • Would like Lockout #1 to lock TURBO only
    • Could have easily added strobe with mode double-click
    • Body is a little smooth
    • Locking and unlocking is a little confusing at first
    • Side decal !! is little loud for me

    I really like a lot of things you are doing. Particularly with the beam angle measurements. If you ever want something much higher resolution and fully automatic I have been working on something.

    However I have a concern about one aspect of your testing methodology. How did you measure 310F? The die of the LED almost never goes above 85C in a production light. In general the glass doesn't heat up since light passes through it. If you taped a thermistor to the glass of the light you were almost certainly measuring the temperature of the thermistor as it was roasted by the intense light and not any "real" temperature of the light in normal operation. Objects held in front of a high output floody flashlight can easily catch fire because of this.
