Olight S1R II LED Flashlight Product Review

The Olight S1R II LED Flashlight is able to emit 1000 lumens at its maximum output.

It comes with a second-generation TIR optic lens, which enhances the beam’s performance and gives you a balanced hotspot for excellent clarity.

It is powered by one IMR16340 rechargeable lithium battery, so it is a reliable flashlight and can deliver a lot of power from one single battery. The power is measured by three different colors (green, yellow, and red, respectively), so you can always know how much energy your flashlight has left.

As the second generation in the S1R series, this flashlight is an upgrade from the previous model due to its smaller and lighter design, making it ideal to keep in your pocket during a survival scenario.

In a survival situation, you will need all of your gear to be reliable and safe to use. With this in mind, the S1R II is designed with a texturized body pattern, so you’ll be able to grip the flashlight firmly and comfortably. This ensures that it won’t slip out of your hand when you need it the most.

Included with the flashlight is an MCC II magnetic USB charging cable, which is also compatible with all Olight MCC rechargeable products. The cable is thin and easy to carry in your backpack, and has a fast 1A charging speed for extra convenience.
