The ornamental design for a photoflashlampunit, as shown and described.
The FIGURE is a perspective view of a photoflash lamp unit showing my new
design.
The broken line disclosure of the end connectors is for illustrative
purposes only and forms no part of the claimed design.
The side and the end of the device which are not shown are identical to the
side and end which are shown. The rear of the device is substantially
planar and unornamented.
