    Super search flashlights

  2. Best flashlight ever! 5 Star Review

    Posted by on 21st Feb 2018

    When I received my flashlight I went out side after dark to see how far this light would throw a beam and to my surprise the beam seemed to go on forever. I have yet to see a better flashlight!!

  3. It’s a great thrower. 5 Star Review

    Posted by on 15th Feb 2018

    Great thrower and overall craftsmanship. Would commend.

  4. MONSTER 5 Star Review

    Posted by on 14th Feb 2018

    If you want to see everything, this is it. I wish they still made the rechargeable one though. The only thing I might suggest is maybe getting the tn40 because can you really even see at distances of 1000 meters +? I know my eyes can't. Those extra lumens with the tn40 might be more fun.

  5. Cloudbreaker ! 4 Star Review

    Posted by on 10th Feb 2018

    I have a lot of good flashlights, but this is my only real "cloudbreaker". With this, i can mostly reach, and light up the clouds at night. And get a feeling like flying up among the clouds ! and be over the rainbow! pinpoint the stars for my kids! Yes and i am very excited about what Trunite will do in the future ? So i can really recomend this flashlight, the only reason why i dont give it 5 stars is that it is big, but to perform this fantastic trow, i guess you must have this big lens. And well, its not a everydaycare edc flashlight, but it could get you over the clouds and for a moment imagine the sun in your life! as well as see the things, you need in your profession or spare time, the cloudbreaker TN 42 are here !

  6. TN 42 thrower 3 Star Review

    runtime on 4 orbtronic 3500 is short, Was expecting better beam distance.

  7. Wow 5 Star Review

    Posted by on 6th Feb 2018

    great quality, does not heat up, light, and really goes far

  8. Hollywood Bright 5 Star Review

    Posted by on 23rd Jan 2018

    I know a thing or two about optics and light beam transmission, This handheld flashlight is awesome! If you want throw and a tight brilliant beam (think search light in the movie Jurassic Park) in handheld form-here you go! And the light itself just looks BAD in the good but dangerous way. The parabolic reflector reminds me of some kind of light weapon.
    This is a serious piece of gear for those that a serious about photons. Not a toy. Not for kids or the mentally defective. This thing will cook you eyeballs in a split second if you were to look directly into the beam. It's not cheap, nor are the Li batteries but it is well worth the investment, esp for first responders or police. I bought 1, then I bought 3 more before they get banned. Full +++++ rating from me!

  9. Great item! 5 Star Review

    To be recommended!

  10. Very impressive light 5 Star Review

    Posted by on 21st Dec 2017

    This is a very impressive light!
    But of course it is not suited as a general purpose or every-day-carry light as the light is almost pure throw, with very little flood.
    It has great range and my example in neutral white has a beautiful color tint.
    I was very impressed by how good the throw is, even in firefly mode.
    I simply love the one button userinterface, as it is simple and well setup.
    Easy access to firefly, turbo or the three main modes low medium and high.
    If only other manufacturers would use the same UI :D

  11. Delivers on its promise 4 Star Review

    Posted by on 6th Dec 2017

    Must be toward the highest power spot lights out there. This is primarily a long-throw, highly focused, spot beam. Very little flare along the beam. There is a "local" evenly lit but weak area of light useful for avoiding tripping that is sharply cut off at the edges. There was an incorrect assembly in the battery holder that prevented filling the cartridge but the error was obvious and a miniature screwdriver allowed a repair to correct the problem. Battery life seems as advertised.

  12. Najlepszy szperacz 5 Star Review

    Posted by on 3rd Dec 2017

  13. super long throw flashlight 5 Star Review

    Posted by on 13th Sep 2017

    Love this bright light saber like flashlight. The xhp led bulb is amazingly bright. The button is even lighted when it's on and that makes it feel up-to-date. The carry strap comes handy and the included spare parts was an icing in the cake. Love it and many thanks Thrunite.

  14. Amazing reach. 5 Star Review

  15. Fantastic light 5 Star Review

    Posted by on 1st Aug 2017

    This is an amazing light, from when you open the box, and you find the light coddled in the unusually silky, perhaps silicone like bag, to when you unscrew the back - and you realize how fantastically well made it is.

    Put in 4 batteries, the battery cartridge is rugged and well made, and reversible, turn it on, and shine it, and you get to see just how perfect that reflector is.

    The throw on this light is insane, if you live on a farm, you want one of these. Highly recommended.
