  1. Great Floodlight Flashlkight 4 Star Review

    Posted by on 26th Mar 2020

    This is a great flood - very bright, good intermediate brightness, easy to use and super turbo mode is fantastic. It also charges quickly. It is the right size, easy to handle and use. I have 2 minor comments and 1 issue. First, the fully charged blue light covers a large range of charge, so relying on it can leave the battery much less than fully charged. Second, it would be great if the little blue/red light on the power button could be illuminated when the light is turned off - by choice only - making it easy to find the switch in the dark. My only true complaint is the rubber cover for the charging port. This came off easily and was very hard to put back. But the real issue is that WHEN IT IS OFF, THE ELECTRONIC GUTS OF THE FLASHLIGHT ARE TOTALLY UNPROTECTED AND VISIBLE in the hole where the rubber plug attaches. I think this is a major concern. But when I email to get instructions on how to get the rubber plug back in, the response was very fast and helpful - super customer support!!

  2. TC20 3800 COOL WHITE 5 Star Review

    Posted by on 28th Feb 2020

    This is a great little light with a nice field of view . Easy turn on /off button in the dark . Small enough to carry on your belt . This is a lifetime quality light . Truly shines through the night .

  3. Amazing Flashlight 5 Star Review

    Posted by on 5th Feb 2020

    Quality flashlight, super bright, good user interface. I was so impressed with this flashlight I ordered a Catapult V6 and recieved it today. Considering the quality and cost of these flashlights I think Thrunite flashlights are the best on the market! If I buy another flashlight I will look at Thrunite first.

  4. Extremely compact yet bright in NW light 5 Star Review

    Posted by on 13th Jan 2020

    Love the power of this compact NW light. It has a very versatile range of light levels from moonlight to reading to searching levels and effective strobe. The only drawback is there is no lockout feature but I did find that slightly unscrewing the body by the switch will lockout the light for carrying in a pack or pocket.

  5. POWER!!! 5 Star Review

    Posted by on 6th Jan 2020

    3800 lumens in such a small package!!!
    So easy to travel with this torch. The included battery is awesome. The included case is awesome. Packaging/box is exceptional. This is my third ThruNite and I'm sold on them. I own the TN4A and Catapult V6 and only have great things to say about them as well. This light is more of a "flood" than a "spot". It's great for home defense for it completely lights up a room.

  6. Amazing light ! 4 Star Review

    Posted by on 18th Dec 2019

    First major purchase on a flashlight and after countless YouTube videos being watched and research this is by far the best light. Pros the Tc20 is actually smaller than I expected and packs a punch. Low light is probably more than enough for any situation, all other modes are awesome overkill!! Medium and high are just phenomenal the distance,hot spot and flood is excellent. Now turbo is easy to access two clicks on the power button and boom easy and convenient. The memory function makes everything much easier than cycling through every mode which is a time saver for any situation problematic or not helps tremendously. Get this light by any means.

  7. Almost perfect 4 Star Review

    Posted by on 6th Dec 2019

    Great light, neutral color temp is great. "High" should be slightly lower output to be more useful. Side switch a little difficult to find by feel alone. Beam pattern is really nice with a smooth transition from hotspot to flood.

  8. Great EDC 5 Star Review

    Posted by on 29th Nov 2019

    Very bright and small So excellent flood goes great with my Catapult V6 . But I find myself using this more than the v6.

  9. Great qeneral purpose flashlight 5 Star Review

    Posted by on 27th Nov 2019

    New to high power flashlights, first heared of them while watching the Proper People on Utube, I'm very impressed With the TC20

  10. Solid flashlight 5 Star Review

    Posted by on 20th Nov 2019

    Make sure you twist it before you charge up the light for the first time. Flash light is very bright, construction is pretty solid and it has good weight to it. On brightest setting it gets pretty warm, lasts forever when using normal brightness settings.

  11. It’s ok. 3 Star Review

    Posted by on 17th Sep 2019

    Received used light the first time. Dead cell, everything unpacked, an obvious return. Contacted Thrunite. A week later, contacted them again. Was told to ship back at my expense. Received a second used light. No charging cable, obvious scratches where the lanyard ring had been installed and used. Light is decent. Not very noticeable from high to turbo. This one is more to the neutral color even though it is supposed to be cool white. I own 2 catapult v6’s. Both awesome. This light is at best average, when used, it’s less that that.

  12. Best 26650 light 5 Star Review

    Posted by on 31st Jul 2019

    This light has exceeded my expectations! The efficiency, size, quality and colour temperature of the beam are all excellent. I own 2 other 26650 battery lights from Olight (R50 and R50 Pro) but the TC20 in NW gives a very pleasing beam that is nicely in-between cool and warm, a balance of flood and throw and is my favorite. The efficiency is very high and the quality is beyond its price point. I'm keeping this light for a long time!

  13. Great light 5 Star Review

    Posted by on 18th Jul 2019

    This light is one of my favorites. It throws out plenty of light and it is one of my favorites for deer hunting season. This light throws enough flood that it lights up plenty of are when I am looking to find a deer when blood trailing on animals harvested right before dark. very rugged and the workmanship is as always excellent. I would recommend and also buy again.

  14. Great Flood Light 5 Star Review

    Posted by on 21st May 2019

    Bought after reading discussion on social app. To be honest I was infatuated with the Lumens VS. Price (on sale). It is a good combination of flood and throw, and I would highly recommend if that is what you are looking for.

  15. A monster of a light in a small package 5 Star Review

    Posted by on 8th May 2019

    This light is amazing for it's size, like having a search light in your pocket or on your belt. And keeping it charged is very easy and convenient with the USB port. I've had much larger flashlights that were nothing compared to this. Definitely worth the money.
