  1. Amazing reliability and power review by Casper on 3/07/2020

    I got this light back in 2017 or 2018 I can't exactly remember and I have been using it ever since. The Thrunite TN42 or ol' trusty as I call mine is simply superb and has always been useful for spotting anything at range. If I'm being honest I don't really have a use for a light with this much power but it is an amazing light o have in my collection. I would very much recommend this light to anyone who has a large property or something like that and I would also recommend it for anyone who loves collecting torches. Even though newer torches have come out with more lumens and more range this thing is still a powerhouse and won't let you down.

  2. Awesome spotlight review by John on 13/06/2019

    Bought this for the farm where the little M2X-UT was just starting to struggle at 300-350m. This is MUCH better. An excellent spotlight with enough spill to see what's going on around you. It's well balanced in the hand and doesn't feel too heavy. There's a shoulder strap included if you're going to spend a lot of time walking around with it. Can't believe they can get this much light from that tiny little LED. Reflector's a work of art. Needs a fairly quick double click for turbo - if you're too slow it just turns off and back on and I tend to struggle with the whole double click thing - even on a computer mouse. Like all Thrunite stuff I've seen, it's build quality is top notch and the light is nothing short of very impressive.

  3. Thrunite TN42 review by brett on 13/09/2018

    This lights beam goes on forever. Super powerful some people won't need this kind of light power. But if you do then this is the torch for you, also very easy to use. I have yet to find any problems with the Thrunite TN42
