  1. Pocket thrower with great spill ! 5 Star Review

    Posted by on 25th Jan 2016

    My TN4A HI is an impressive light. Fit and finish is flawless. Led is perfectly centered, and the smooth reflector is perfect. Im using Eneloop Pro's and they fit the battery carrier with no problems. It has a lanyard attachment loop hole. Im getting slightly better runtime than the factory specs list. In my homemade lightbox im getting near identical lumen numbers as factory listed. The spot is defined and throws to 250 yards with no problem. The throw is as good as my Solarforce M9 running on 2 18650's. The spill is very nice and larger than I expected. Belt holster is well made. The light came with a lanyard, extra O rings, and an extra switch boot. The TN4A HI has become my new house, outdoor, go to light and gets used every day. Well worth the price and then some.

  2. Fantastic AA thrower! 5 Star Review

    Posted by on 6th Jan 2016

    I'm new to modern flashlight technology. Man I'm lucky. This is all the throw I need and it uses AAs! Easily throws further than I can see the details. Beautiful & powerful beam. Very cool light and a tremendous value at this price. I have lithiums in it now. Waiting for eneloop pros. The lithiums have lasted 3 weeks of constant use. I love it!
