    Amazing flashlight. I have this mounted on an AR15 rifle. I can charge the flashlight with the USB cable which makes it super simple. Its lightweight for the volume of light it emits. Perfect for this application. The service and fast shipping I received was amazing.


    Very good stuff

    Perfect for doing inspections, bright enough when needed most.
