Flash-bang grenade with greater flash intensity

A safer and brighter flash-bang grenade, comprising:

• a pyrotechnic mix of about 50 to about 55 wt. % strontium nitrate, about 35 to about 45 wt. % aluminum powder, about 3 to 6 wt. % sulfur, about 0.5 to about 1.5 wt. % boric acid, and about 0.5% anti-caking agent;
• the pyrotechnic mix being held in a reaction chamber composite housed within the body of the flash-bang grenade, which body has a series of light/sound venting ports;
• the reaction chamber composite being formed of an inner sleeve of aluminum with a thickness of from about 0.002 to about 0.020 inches, an aluminum charge holder with a thickness of at least about 1/10 inch slip fit about the inner sleeve, and an outer sleeve bonded about the charge holder;
• the aluminum charge holder having a plurality of vent holes through and about its circumference;
• wherein, upon ignition, the flash-bang grenade will emit a peak sound level of about 180 db measured at 5 feet therefrom and emit a peak light intensity of about 13.5 million candela.
