A luminous bullet that is fired from a cannon, rocket launcher, or flare gun, or dropped from an aircraft, to provide illumination. It is used for nighttime attacks, target identification, photo reconnaissance, and aircraft landing guidance. The illuminating agent used is a mixture of magnesium or aluminum powder and barium nitrate. It has a luminous intensity of tens of thousands of candlelight, and its flight time can be increased by using a parachute.
