So, how to choose a good survival flashlight? Here are some advice for you.

1. It should be a tactical flashlight. A tactical flashlight can defense us in emergency. We can use it to fight against the dangerous guys or beast.
2. It should be waterproof. Imagine that if your flashlight is dropped into water and cannot work again, then, you are helpless. So, the flashlight should be waterproof.
3. It should have high-light mode, more than 500 lumens. Super bright light can scare beast away.

Meanwhile, you may need some other features, but the four features are necessary in my opinion.
