Abstract
A multilamp photoflash unit includes a housing member having a plurality of lamp-receiving cavities of a relatively opaque material with a reflective surface adjacent the lamp whereby back radiation from the lamp is reduced. Also, a reflector having cavities of opaque pigmented plastic resin material and a reflective surface may be disposed within a plastic housing and serve to inhibit back radiation from a lamp.
