A photoflash lamp array comprising a plurality of flash lamps having lead-in wires connected to a circuit board carrying switching circuitry for sequentially firing the flash lamps. An electrically conductive reflector unit is positioned between the lamps and the circuit board. A conductive clip is clipped to the reflector unit and touches against an electrical ground point on the circuit board, whereby the reflector unit functions as an electrical shield for the circuitry.
