Abstract: A hazardous location light source module includes a metal base carrier having a light-module support surface on its upper side and a mounting stem on its lower side. The light-module support surface supports a light-module substrate mounting one or more light-emitting devices. The mounting stem is configured for mounting the light source module to a modular hazardous location light source assembly. A wiring port extending through the mounting stem to the base carrier upper side receives electrical wiring that connects electrically to the light-emitting device(s). A main-lens support surface on the base carrier upper side supports a light-transmitting main lens that comprises chemically strengthened glass and has a maximum dimension to maximum thickness ratio of not less than approximately 40:1. The main lens is permanently secured to the base carrier by virtue of a base carrier periphery being deformed into a lip that folds over to capture the main lens.
