The X300U is both a "shock" tool as well as an actual impact device securely mounted to the frame.
If someone gets the "flash" in the face, they have already failed to respond to voice commands. Lighting them up can give tactical advantage, taking their night vision away and momentarily blinding them.
General search or illumination is the light hitting the floor and spilling around the area. Muzzle down in the ready position. I have found NO negative to my vision and it has been tested thoroughly.
Nice to have when checking the barn and critters at night on the farm.
