Surefire got an updated presentation about their Turbo Series of weaponlights... "The SureFire Turbo series pushes the limits in both handheld and weapon-mounted lights to give you the upper hand in any hostile encounter, near or far. Every Turbo model delivers high-candela illumination that reaches out to extreme distances.
