A light includes a housing part and a translucent cover connected to the housing part, in a pressure-tight manner, by a screw-on ring. A flame-extinguishing gap is formed between the housing part and the cover. The flame-extinguishing gap is formed directly between a surface of the cover, and a surface of the housing part, and the screw-on ring covers the flame-extinguishing gap at the gap end pointing to the outer side of the light. |
