  2. An Exceptionally Well-Designed and Extremely Bright Flashlight! 5 Star Review

    Posted by on 18th Nov 2016

    The Thrunite TN40 is an exceptionally well-designed flashlight —not to mention, extremely bright and a very long distance beam thrower!
    It's also not as large as it appears in pictures, and strikes up a perfect balance in terms of it's size, weight, and very intuitive control switch —this, for single-handed operation.
    Furthermore —and the proverbial "icing on the cake", so to speak— is that one never has to worry about purchasing and changing batteries, as the TN40 is rechargeable and comes with it's own AC charging cord and adapter.
    Additionally, the inclusion of a multi-colour LED button, located on the tail-end of the flashlight, serves as both a power level and charge status indicator.
    Last of all, and typical to any and all Thrunite products, the build quality and fit-and-finish are top notch.
    So very well-done Thrunite! A definite 10 out of 10 product!

  3. Great Flashlight 5 Star Review

    This flashlight is just what they say it is. Top quality and powerful. I am very satisfied with it.

  4. Brighest searchlight/general purpose 5 Star Review

    Posted by on 9th Oct 2016

    Carefully manufactured, tailstand compatible, easy to use interface. EXTREMELY bright and - quite surprising - this also with respect to its throwing spot. Gorgeous job with respect to the reflectors! Included rechargeable battery charging pack appears perfectly ok to me, since charging times are pretty short. Time will show durability of rechargeable batteries. Nice feature: LED indicator of battery capacity included with pack.

    This flashlight is large but still good to handle due to balanced weight distribution.

    One point of critique: The portion of the head where the lanyard goes has sharp edges which bear the risk of (slight) injury.

    Taken together - if you want a VERY bright light, there is no alternative currently to the TN40 imho.

  5. Incredible Search Light 5 Star Review

    Posted by on 15th Sep 2016

    This has been a great light so far. I've had it a little longer than a month and have mainly used it for spotting wildlife in my yard before the dog can tangle with it. The user interface is easy to use and the carrying strap is very helpful as well. I like the battery check button at the rear of the light but in truth, I use the light for short durations so I'm not even down to 80% battery yet. The lanyard attachment points at the rear of the light Ae very robust and also allow for tail standing. With the light on High (not turbo), ceiling bounce will light my whole large bedroom brighter than it is with all my lights on! I've been very happy with the spill light from the beam as well: it makes navigation using only this light very easy (as opposed to using a headlamp in addition to it). I would definitely recommend this light.

    This light is amazing, strongly built body, huge reflector, SS switch. The beam distance is remarkable, there is no comparison with other lights in this category.
    There is only one contrary, the battery pack. When its depleted you don`t have a chance and time to recharge it in the field. If it were a replaceable with 4 individual 18650 batteries that would be great. I don`t think that TN sells spare battery pack for this light.

    I first learned of this offering from You Tubes " we all juggle knives" If you want a thorough review, visit his channel. Mine is everything that is advertised and an awesome addition to my other ThruNite's. I've had no problems with any.

    Posted by on 20th Jul 2016

    Super amazing thrower! Stands up to HID. Flashlight has a pretty light weight feel to it for its size. Love the fast charge. If you want a monster thrower, this is the light for you. Excellent build quality and feel, worth every penny
