Up until a few months ago I had never heard of Thrunite. The leaders of the high quality flashlight pack are names like Surefire and Streamlight. Those guys better up their game because Thrunite is offering a quality product at a very affordable price.
Full disclosure: I received the Thrunite TN4A at no cost to myself. Receiving a sample at no cost to myself will not influence my opinion as I look at the results of the test. The most important factor is if the flashlight passed all of the test and continue operating.
The test: Some of the youtube viewers have accused me of abusing the flashlights in my test. One example is the Thrunite TN12 review where the flashlight is put through all kinds of test. Some of the viewers asked what running over the light with a tractor proved. Some testers run over gear with a car or truck, so I thought why not be different and use a tractor. Due to the feedback I decided not to run over the Thrunite TN4A with a tractor.
