    Abstract: An electrically-activated photoflash lamp which includes a thin member (e.g. a mica disk) therein located between the lamp's combustible shreds and primer material. The disk prevents the shreds from contacting the primer material and any portions of the lamp's electrical conductors which have access to the interior of the envelope. A method of making the lamp is also provided.
