  1. TC20 Review 5 Star Review

    Posted by on 1st May 2019

    The TC20 was the first ThruNite flashlight I purchased. The shipping was very fast and the package was as advertised. The LED is very bright and the UI is easy to use. It is a little big to be used as EDC but very suitable for my long hiking trips. The battery is long lasting and has enough juice to go along with 2300 lumens even though I mostly use it at high brightness (1000 lumens or so). The build quality is excellent with nice anodized aluminum body. I accidently dropped it once on a paved road and no issue or scratches were observed. Overall, I am very satisfied with the flashlight and the quality of that product made by ThruNite. They convinced me to go further and now seriously thinking to buy a TC15 as my EDC unit.

  2. Awesome !! 5 Star Review

    Unbelievably bright for how small it is build quality is excellent. USB charging is quick and convenient. Buy it you will not regret it!

  3. The Little Beast 5 Star Review

    Posted by on 16th Apr 2019

    I have Fenix, Nitecore, Olight abd other Led flashlights but the TT 20 is the light I am most impressed with. It is simple to operate and is USB rechatgeable. If I had to improve it I would like to see a sturdier belt holder, some knurling on the on switch to make it easier to find in the dark and an anti roll barrel. Other than that it is a GEM!

  4. Love it! 5 Star Review

    Posted by on 10th Apr 2019

    I got the light for my husband's birthday and he loved it! So naturally I was happy that I made him happy. It has a bright light and love that he can recharge it in his truck as he is driving.

  5. as advertised 5 Star Review

    Posted by on 10th Apr 2019

    I happened to be watching a vlog about a young man who spends tremendous amount of time in the woods and in the winter where he is building a cabin with his Dad. I, too, camp a lot although not typically in the dead of winter. Flashlights are crucial pieces of technology that I covet and in one of the episodes I watched, the young man demonstrated his Tc20 and I was amazed. I ordered one that day and when it arrived I was duly impressed with the super quality it contained. I couldn't wait until dark to see just how impressive the light was and I wasn't disappointed. I have other hi-tech flashlights but nothing of this caliber. I will most definitely recommend to my other out-doors buddies for certain. Telling them to spend close to $100 for a flashlight, however, will require that I demonstrate it to them! That will sell them on it for sure. Worth every penny.

  6. TC 20 5 Star Review

    Posted by on 6th Apr 2019

    As one who has purchased 7 Thrunite lights, again I’m impressed. From the size to brightness ratio to the strength and ergonomics and price, this is another great product that goes unmatched market wide. Regardless your choice, one cannot go wrong with any Thrunite product!

  7. Great flashlight 5 Star Review

    Posted by on 2nd Mar 2019

    Bright and sturdy

  8. Good light but has two problems 2 Star Review

    Posted by on 2nd Mar 2019

    I like the light. It's bright and has four distinct settings. I drop it to three stars because (1) turbo isn't any brighter than the "high" setting and (2) the light only goes to the "high" setting if you hold it down and cycle until you get to high. If you go to medium and pause for a few moments, it goes back down to low, not high. You must hold it down at low and not pause until you get to high. If the light performed as advertised, I'd give it 5 stars. As is, I would not buy again.

  9. Do not drop the TC20 1 Star Review

    Posted by on 12th Feb 2019

    TC20 was on lowest setting when it rolled off the counter in the dark, landed on ceramic tile. Now I can not turn it off or change the brightness. It is stuck on in the lowest setting after falling onto the floor.

  10. so far so good 4 Star Review

    Posted by on 11th Feb 2019

    I like the neutral white. Nice color. But not as bright.

  11. Extremley practical 5 Star Review

    Posted by on 4th Feb 2019

    You can illuminate an entire room with this flashlight by pointing it to the ceiling. The throw is far enough. The broadness of the light, ease of charging, replaceable battery, and pocket friendly size make it extremely practical.

  12. Lot's of light in a small package! 5 Star Review

    Posted by on 19th Jan 2019

    The TC20 is simply an excellent all around flashlight. Yes, a bit large for a pocket, but carries well in the holster, or in a coat pocket. Outstanding run times, and levels seem to be just what I need. Love the USB charging too. Well done Thrunite!

  13. Super bright and fits in the palm of your hand 5 Star Review

    Posted by on 13th Jan 2019

    Solid, we'll finished flashlight. I use it daily.

  14. Quality throughout. 5 Star Review

    Posted by on 29th Dec 2018

    I own three thrunite flashlights at this point. I have found all thrunite products to be high quality. Would definitely recommend this company. Great group to deal with!

  15. Extremely Bright! 5 Star Review

    Posted by on 28th Dec 2018

    Very bright, flashlight feels durable and well made.
