A light for a submersible pressure vessel is partially mounted within the interior of the pressure vessel and has a metallic element mounted in a wall of the vessel and extended outside the pressure vessel from this wall. The light further includes a container sealingly closed by the metallic element. The container is composed of two translucent bulbs spaced from one another to define a cavity filled with water. A light element such as a lamp is inserted into the inner bulb and extends outside the pressure vessel so that its electrical cable is positioned outside the vessel. A cooling member is connected to the metallic element to remove heat generated by the lamp and transmitted through water and the metallic element. |
