  1. Awesome Light 5 Star Review

    I own several flashlights from various brands. I enjoy the UI of Thrunite the best of all of them. Simple to use and intuitive design make these light easy to use. I thought that I would never use Firefly mode, but I find it to be very useful. Overall construction is great. Performance is as rated or better. I would definitely recommend this light!

  2. Never turned on 1 Star Review

    This flashlight is garbage. It never even turned on. I told support I threw it away and that’s the last I’ve heard from you. Great customer support! (I’m being VERY sarcastic)
    What’s that old saying, great products will get a little word of mouth but EVERYBODY will hear about crappy products.

  3. Initial problem solved 5 Star Review

    Posted by on 30th May 2018

    When first received the light wouldn't turn on. I unscrewed the battery pack. There seems to be a spring loaded contact button in the battery pack that mates to an identical button in the head that holds the CREE. The button appeared to be cocked at an angle. I pushed on it with my finger to get to protrude flush instead of skewed. That seemed to work as the CREE is now getting power. Light works as advertised, I'm glad I bought it. WOW! IT IS BRIGHT!

    I find that the light performs superbly. I do recommend the light, it really shoots a beam far into the night. It comes with an adjustable sling.

    I love this light!
    It shines so bright and so far, it's just amazing.
    The build quality is extremely good as well.
    It is quite big and a bit heavier than expected, but I love it!
