  1. Wow this think is Bright. 5 Star Review

    Posted by on 22nd Apr 2018

    This is the second Thrunite. I have a p12 and not the TC20. They are both very nice lights. You can tell when you pick it up that it is high quality. TC20 is very solid and the attention to detail is very high. Wow, this thing is bright and reasonably priced. I cannot believe that something this small could be this bright. I would recommend and I plan on buying more.

  2. Turbo 4 Star Review

    Posted by on 21st Apr 2018

    This is a great light for a great price. My only complaint is the Turbo mode. The book says High is 1800 and Turbo is 3800. Their is only a slight difference between them and requires cleaning the contacts for the battery.

  3. Great performance for the size. 5 Star Review

    Posted by on 21st Apr 2018

    This is a great light for its size and price. The output is one of the best for its size, currently. I have the NW color temperature which renders good color accuracy. The beam pattern is a very useful distribution between flood and spot. This may not be a good candidate for EDC because of its diameter, but it is a great home, vehicle, camp or belt holstered light.

  4. Exactly what I expected! 5 Star Review

    Posted by on 20th Apr 2018

    This is my 3rd Thrunite flashlight. I also own 2 headlamps, and numerous Thrunite charging systems. Thrunite has earned my loyalty with quality products that provide excellent value.

  5. Amazing Light! 5 Star Review

    This is another amazing light I got from Thrunite. It’s a great product.

  6. ThruNite TC20 3800 Lumen Flashlight 5 Star Review

    The Thrunite TC20 rechargeable flashlight is small, powerful and well made. I am very happy with my purchase.

  7. The TOP 5 Star Review

    Posted by on 22nd Mar 2018

    Cette lampe est parfaite:
    -très bonne prise en main
    -éclairage de qualité sans point chaud
    -puissance hors norme !!!
    -une seule batterie 26650 qui suit sans problème la puissance

    J'en ai commandé 2, rien à redire, qualité THRUNIGHT comme d'habitude.
    Un MUST !!!

  8. Most practical flashlight EVER 5 Star Review

    Posted by on 21st Mar 2018

    It's easy to find bright flashlights but hard to find flashlights that can maintain the high lumens for practical usage. Typical flashlights on Turbo dim rapidly to 20% of the start up lumens.

    My only complaint is the emitter choice has too much green tint. This looks like a B or C tint. I wish it was A or D which would make it less green/yellow and more neutral/rosy. My 4000k XHP70.2 80CRI flashlight has no green and less yellow than this 5000k XHP70.2. My XP-L HI 4000k 5D tint is much less yellow than this.

    Otherwise, this would be the perfect flashlight.

  9. crazy bright! 5 Star Review

    Posted by on 17th Mar 2018

  10. amazing! 5 Star Review

    Posted by on 16th Mar 2018

    soooo nice !

  11. My first Thrunite flashlight 5 Star Review

    Posted by on 14th Mar 2018

    My first Thrunite product and certainly not the last! The light is smaller in person, has a nice balanced weight to body ratio, the button has a nice unique click to it, it looks and feels greatly CNC machined body and anodized, lens are high quality, everything is high quality, even the springs inside and threads are smooth and lightly oiled. It's very bright, with original battery there is a bare difference between 1800 lumens and 3800 lumens, I'm waiting for a liitokala 26650 battery. Overall you won't be disappointed with this light, it's a sun in the hand.

  12. Down work 1 Star Review

    Flashlight did not work

  13. Super Bright. 5 Star Review

    Posted by on 11th Mar 2018

    Very! Very! Bright little flashlight.

  14. Belle lampe 4 Star Review

    Posted by on 11th Mar 2018

    Lampe compacte et très bien construite , simple d’utilisation , malheureusement je ne vois pas de réelle différence entre le mode high et le mode turbo.

  15. Small light yet very bright 5 Star Review

    Posted by on 10th Mar 2018

    I ordered on Feb 22 and recieved on Feb 25.I really like this flashlight.This is a complete package included battery and holster.I like the convinience of USB charging and the battery indicator on the button. The 26650 battery provides a long runtime .It is palm sized yet turbo mode gives you 3800 Lumens and unlike other lights it does not get very hot or 50 second stepdown while on this mode (It sustained 6 minutes ).One slight twist of My only wish is that the holster were a better quality.
