A photoflash lamp having a glass envelope with a clear protective exterior coating comprising a photopolymer reinforced with glass fibers. In applying the coating, a long strand of glass fibers is wrapped about the lamp envelope, which is then dipped in a liquid photopolymer, or short lengths of glass fiber are dispersed throughout the liquid photopolymer, either by premixing or application after dipping. The wet-coated lamp is then cure-hardened by a short period of irradiation with a source of ultraviolet light.
