    Default Review: Nitecore HC35 (Headlamp, micro USB rechargeable, 21700, 4XPG3, 3000+ Lumens)

    I received the Nitecore HC35 from Nitecoree for the review.
    The HC35 is the first Nitecore headlamp to feature a 21700 battery, with integrated micro USB charging, that powers 4 XP-G3 emitters. The HC35 also features an ATR, a system that balances the output of the light depending of its temperature.

    The light comes in this box



    The content of the box: the HC35 with NL2140HP battery (Nitecore 21700 4000mAh protected battery), clip, headband with headband support, spare o-rings, micro USB cable, manual, warranty, 18650 adapter.



    The HC35 measures 128 mm in length, is 26 mm wide mm at the body, and the head measures 29x31 mm.




    Here in my medium hand.




    The single stage electronic switch, with a blue LED underneath it, is under the rubber cover.



    On the back of the head thereís the micro USB charging port, with its rubber cover.



    The TIR Optic with the 4 XP-G3 emitters.




    Notice the deep cooling fins on the head of the HC35, needed to dissipate the great amount of heat generated at turbo level.



    The tailcap has a magnet in it, allowing it to attach the light to metallic surfaces. The magnet canít be removed.




    The tailcap is the only portion of the light that can be unscrewed. The tailcap threads are anodised, allowing for physical lockout, and are triangular cut.



    The headband is made out a thinner, more perspirant fabric. It also has a line of silicone to avoid slipping and the sweat to run down on your forehead while using the light.




    The light is connected to the headband via a metallic clip on the headband mount. It holds the light in place well, and can rotate. If you have attached the clip to the other side of the body, the clip can be left in place while the light is on the headband mount.



    Hereís the interface



    Output and runtime
    Both tested with the provided Nitecore NL2140HP.





    Here is how hot the light is when, at room temperature, turbo mode canít be re-activated for more than a few seconds, after 4 or 5 cycle of turbo-stepdown

    My thoughts
    The light is well built and finished.
    I like the UI with direct access to lowest and highest mode.
    With only 5 levels available for a max output of 2700 lumens, it makes hard to distribute well the output, making a big step when going from 800 lumen of the high mode, to the 2700 lumen of the turbo mode.
    The metallic clip used to secure the light to the head mount makes the connection secure and easy to rotate the light, while potentially keeping in place the pocket clip. But it will scratch the anodisation overtime.
    The HC35 is a good choice if you need extended runtime at higher output.
    This light can run with a smaller 21700, like the one I have with only 4000mah, for more than 2 hours at more than 800 lumens, even without cooling. This is especially good for people that use their light for work or in general have a need for the highest runtime possible, without carrying an additional battery.
    A nice plus is the fact that the micro USB charging port allows fast charging, up to 2A, which means you can charge your 21700 in around the same time you would need for a regular 18650, power adapter permitting.
    The Turbo output lasts shortly due to the huge heat produced by the light (remember this HC35 is a bit bigger than a normal 18650 headlamp).
    I would like to see this light with an additional level and a warm tint.

    Thanks to AntoLed, Won, Zampa.

    added runtime plot for high mode with cooling.

    I don't see any pics of this light on a head. Seems like it would be kind of large and weighty.
