Abstract: A through-hull light for a marine vessel is provided. The light includes a body for mounting on the outer surface of a hull, having an outer side facing water and an inner side for mounting against the hull; a chamber formed within the body having a transparent screen mounted at an outer side; a shaft for extending from the inner side through an aperture in the hull; LEDs mounted within the chamber in parallel rows and arranged to be horizontal when the light is mounted through the hull, with each LED mounted to direct light out of the chamber in a first direction perpendicular to the inner side; a reflecting structure within the chamber having a plurality of reflectors positioned above or below a row of LEDS and parallel therewith, with each reflector formed to reflect light away at a fixed angle vertically from the first direction.

Abstract: An underwater lighting apparatus includes a cofferdam having a cofferdam electrical connector rigidly mounted within the cofferdam at an inner end; a lighting unit sized and shaped to be mounted within the cofferdam and having a lighting unit electrical connector rigidly mounted at an inner end; wherein the lighting unit electrical connector is sized and shaped to directly connect with the cofferdam electrical connector to form a rigid connection between the cofferdam and the lighting unit. The lighting apparatus is beneficial in that both the cofferdam electrical connector and the lighting unit electrical connector are rigidly mounted.
