A photoflash lamp unit having an array of eight flash lamps located on each of two opposing sides thereof. Each array comprises two regions, upper and lower, of four lamps. A pivotal mounting device at a lower end of the unit permits the four lamps in one upper region to be fired after which the entire unit is rotated and the four lamps in the remaining, opposing upper region are fired. The unit is then inverted and the eight lamps in the two previously lower regions are fired in the manner described above.
