  1. Big Light Small Size 5 Star Review

    Posted by on 17th Feb 2018

    The TC20 has big light power in a very convenient size. The form factor is excellent,and so is the build quality. Incredible power from this flashlight! Buy one you won’t be disappointed.

  2. TC20 NW 5 Star Review

    Posted by on 13th Feb 2018

    è un ottima torcia ben fatta ben costruita, leggera, abbastanza piccola, ricaricabile tramite usb e facilmente trasportabile con la sua custodia... viene venduta già con la sua batteria 26650... emette tanta luce...3800 lumen in turbo sono tinta NW è ottima tipica di altre torce thrunite che possiedo e secondo me motivo del successo di vendite in europa...altri marchi vendono solo cool white spesso fascio luminoso però pur essendo flood in base al tipo di led ed alla parabola orange peel però non è molto ampio poichè la testa della torcia è piccola... cosa che non può essere considerata un difetto ma piuttosto una caratteristica...come sempre ottima thrunite anche nella spedizione...

  3. Good flashlight 5 Star Review

    Posted by on 9th Feb 2018

    It very whell made and it is a 5star product.

  4. well made 5 Star Review

    Posted by on 7th Feb 2018

    Like the tc20 so far. brightness is great and the beam pattern is excellent. My only wish is for a level 0f 700-800 lumens,as the jump from 300 to 1800 is too large.Interface is good,and I like that a long press from firefly gets me to low, so you don't have to turn on the light in an unknown brightness level.Once you get used to two long presses, it's great.Very solid light, like my V5 catapult,well done

  5. The cover for the charging port cover fell off the first time I was wearing it in the holster on my belt, and I lost it. 3 Star Review

    Posted by on 6th Feb 2018

    Need to work on the charging port cover. I would like to find out how to replace it.

  7. Unbelievably Bright Light 5 Star Review

    Posted by on 3rd Feb 2018

    The main use of the light is to take the dogs out in the back yard at night . When I put it on the highest power is like turning the stadium lights on for a night game.

  8. Powerful, yet Compact 4 Star Review

    Posted by on 3rd Feb 2018

    The 26650 5 amp-hour battery required for this light is the same length as, but appreciably wider than, the 18650 3.5 amp-hour battery that we have become familiar with, so the diameter at the tail end of the knurling is 1.25 in. rather than the 1" (±) to which we are accustomed, making the tail cross-section 1.56 times as large as, say the TC 10. That, with the wide head diameter of 1 11/16" and the shorter length (4 11/16") gives this flashlight a much 'clunkier' look than most of the 1,000 lumen EDC lights we see. But those dimensions make its tail down stance very stable even with the lanyard (which comes off the side of the base) attached. The shorter length is, in part, achieved because the lack of a tail switch eliminates the need for a guard.
    The USB recharge port seals well (when you press it firmly).
    The on/off/mode switch on the side near the head is well thought out. Just turning it on will not yield either firefly, turbo, or strobe mode, but you can go to any one of these directly from 'off', and the light 'remembers' which of the other 3 modes was used last.
    Despite the TC20's less than gracile look, I find it quite suitable as an EDC flashlight.
    The sheath provided has proven adequate so far, though it could be sturdier. For that and the lack of a tail switch (which is partially offset by above-mentioned considerations), I have withheld one star, albeit somewhat reluctantly. Given the power, quality of construction, and the price point, I find this to be a very good value.

  9. sehr gut! 5 Star Review

    Posted by on 3rd Feb 2018

    eine kleine lampe mit sehr viel power. sie hat eine lange laufzeit. die bedienung ist so wie ich sie mir wünsche. eine wirklich sehr gute lampe.

  10. Let there be light! 5 Star Review

    Posted by on 1st Feb 2018

    There is no question this is a 5 star light. Really like the
    26650 battery and the extreme amount of light. I got the
    Neutral white and the tint is very good. I would like to see
    Thrunite offer a smooth reflector option with this light. I
    Live in the country and would like to see a farther throw
    For spotting longer distances with the same size light and
    Battery. But if you want to turn night into day in your yard
    This is the light you want. Well done Thrunite.

  11. Nice Flood Light For Size 5 Star Review

    Posted by on 31st Jan 2018

    It’s small but puts out a nice flood light effect. My son carries it in his first aid kit that he takes everywhere. It replaced the Neutron 2C.

  12. TC20 - good but far from perfect 3 Star Review

    Posted by on 31st Jan 2018

    Nice and powerfull but a little too small in hand. It does not give you a "safety" feeling like other similar products. I like 26650 flashlights and I have six others. I'd put the TC20 in third place.
    Good quality construction. The battery is quite longer than similar batteries. Overall a good flashlight for home and every day use but with some drawbacks.

  13. Incredibly bright compact flashlight 5 Star Review

    Posted by on 30th Jan 2018

    This is an exceptional flashlight. The five brightness levels are very well chosen to span Firefly through Turbo. In Turbo mode, the very highest light level only lasts for a second or so -- the LED quickly gets hot -- but remains extremely bright. The flashlight is solidly built. The rubber cover for the USB slot is the only weak point, but most USB devices don't even have a cover. I would prefer a rear button because the side button is sometimes a little hard to locate in the dark, and once I pulled it out of my pocket and found that it was on. It does not throw as bright of a beam as a Duracell 1000 lunem light when focused for distance, but the total light output is clearly much more. Adding a focusing lens to the TC20 would probably ruin the compact design. The beam is spread very smoothly over a fairly wide angle.

  14. Great hand cannon 5 Star Review

    Posted by on 30th Jan 2018

    Good quality as expected from thrunite. Great ui with a true moon light and a pungent 3800 Lumens on turbo.

  15. What A Great Little Light 5 Star Review

    Posted by on 29th Jan 2018

    I got this to replace an Olight R50 Seeker. The reason, the low on the Seeker is 50 lumens, way to bright for low. The TC20 is .5 lumen, which is perfect for taking the dogs out at 5AM. This light fits perfectly in your hand, has a great range of light output and nice run times. Recharging via USB can take a while but that's expected as it is a 5000mA battery. Over all, a really great light.
