The Anglo American Suprabeam flashlight, No. Q4xr, utilizes the hyperfocus LED light-focusing technology that produces high light output by limiting optical light loss. The Q4xr offers 680 lumens with a run time of 14 hours, all in a sleek 5.25" design made of anodized high strength aluminum. Additionally, the Q4xr utilizes Suprabeam’s own HYPERFOCUS technology that provides a smooth control of the beam focus from spot to flood at a 250-meter distance. The rotating head keeps the light beam in optimal position ensuring the highest light output while limiting optical light loss to a minimum. It offers five available light modes.
