  1. Great flashlight 5 Star Review

    Posted by on 2nd Mar 2019

    Bright and sturdy

  2. 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.

  3. 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.

  4. so far so good 4 Star Review

    Posted by on 11th Feb 2019

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

  5. 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.

  6. 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!

  7. 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.

  8. 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!

  9. Extremely Bright! 5 Star Review

    Posted by on 28th Dec 2018

    Very bright, flashlight feels durable and well made.

  10. Great build Quality 5 Star Review

    Posted by on 22nd Dec 2018

    Excellent build quality, good compromise between throw/spill IMO. I bought 2 of these, my only complaint is the first one was purchased on Amazon, but then realized there was 20% off on the Thrunite web site, even though the Amazon purchase was fulfilled by Thrunite no hint of the 20% off. Would be a much happier customer if I could get a credit for the 20% discount. I own 14-15 Thrunite flashlights.

  11. Thrunite tc20 5 Star Review

    Posted by on 20th Dec 2018

    Actually ordered this as a Christmas gift but I tried it out being somewhat a flashlight junkie. Very impressed with it. Very bright with good runtimes and in such a small package. I won’t buy a flashlight unless it’s rechargeable and might have to pick up one of these for myself. Highly recommended if your looking for a small powerful rechargeable light.

  12. A Bright light! 4 Star Review

    Posted by on 20th Nov 2018

    I use it when filming in underground mines. It is very bright and lights up large stopes well. I had to replace my first one I dropped it only a few inches and the glass broke on a rock so they are a little fragile.

  13. Very powerful 5 Star Review

    Posted by on 13th Nov 2018

    This lite is unreal for it's size, it really lites up everything

  14. as good as i hoped it would be 5 Star Review

    Posted by on 19th Oct 2018

    i received this nicely packaged TC20 in NW today in the mail. i charged it up until the light turned blue. out of the box i love the small stature and solid feel. the light screems quality and the output is exactly what i hoped for. it lights up a room when you put it on high/turbo. very usable and the size is perfect to keep inside a coat pocket. the color of the beam is perfect. overall a great item and a decent price point.

  15. Perfect walking light 5 Star Review

    Posted by on 16th Oct 2018

    The light is smaller than you would think. Shorter than some of my 1 x 18650 lights, but a bit wider. Overall it’s very comfortable to hold.

    The beam shape is perfect for an all around light. The low mode is great for close up work. Medium is perfect for walking. It had enough throw to see further away objects, but it also has a nice wide hotspot and bright spill. High and turbo is great for lighting up everything in front of you.

    I keep the light by our front door and use it for walking at night, taking out the trash, camping and for everything else I might need a light for.
