A filamentary-type photoflash lamp suitable for use with a relatively low voltage high current power source includes a glass envelope with a shredded metal fill, a pair of leads interconnected by a filament wire and a primer having percussively-ignitable and powdered combustible incandescible material on the leads with the primer material responsive to heat generated by the filament wire. A process for fabricating the above-described photoflash lamp is also provided as well as a primer material composition.
