ThruNite BSS V4 Tactical Flashlight

With a modern flashlight, you get a powerful LED, long battery life, and great color rendering.

While for campers, anything over 1,000 lumens is too much, there are situations, when you need a strong flashlight that can show you very distant objects in the dark.

And sometimes you need more.

Something like ThruNite BSS V4 Tactical Flashlight.

ThruNite BSS V4 is a powerful and versatile 18650 flashlight with a strike bezel handheld. As you probably know, 18650 flashlights are essential pieces of equipment for self-defense and illumination in low-light conditions. Such tools are ideal for camping, hiking, and emergency use. And self-defense, of course.

With ThruNite BSS V4 you get a weapon flashlight that can go places where firearms can’t. Some countries restrict what you can carry in self-defense, and a tactical flashlight is a great alternate weapon if you cannot carry a knife or firearm.

When it comes to ThruNite BSS 4 Tactical Flashlight, versatility is the name of the game. It does boast a maximum output of 2523 lumens, and a LED bulb that is able to produce a beam of light up to 820 feet (250 meters).

On top of that, it comes with 6 lighting modes: Intelligent Firefly, Low, Medium, High, Turbo, and Strobe. This makes the flashlight perfect for many different outdoor activities.

A part of the reason, why ThruNite BSS V4 is great for a wide range of situations, is the waterproof rating of IPX8, compatibility with a rechargeable 3100mAh IMR 18650 Lithium-Ion battery that offers simple USB magnetic charging and can run for up to 56 days when you use only the Firefly lighting mode.

This tactical flashlight is designed with high-quality aluminum alloy, and an anodized anti-abrasive surface finish in a black color which offers great durability for a long time daily use.
