This grenade cut from Fallout: New Vegas was meant to inflict fatigue damage to targets, allowing for a less-lethal explosive weapon. Typical of stun grenades, a bright light accompanies the detonation, which can momentarily blind or blur vision.
Flash grenades, by themselves, do very little harm. They instead use a magnesium core to release a blinding flash upon detonation, stunning opponents caught in the blast radius.
