Its, bright, powerful and runs on a single 18650. The beam is very laser like on full focus, good for about 600-700 yards. Its also useful as a regular flashlight because its zoomable, and has the multilevel brightness functions of the Adventure Sport Flashlights™ UI.
THE FINE PRINT<——-
I built this light as a prototype. This means its been apart and together in many forms and show some signs of wear. There is a small chip in the lens at the very edge ( does not effect the beam that I can see) and a couple of small dings where the head and body meet.
