A marine system, comprising:

• a marine vehicle;
• at least one lighting assembly attached to the marine vehicle, wherein the at least one lighting assembly comprises:
• a housing;
• at least one chip-on-board light-emitting device comprising:
• a substrate;
• a light-emitting area;
• at least one lens element positioned adjacent to the housing;
• a second housing;
• a second at least one chip-on-board light-emitting device comprising:
• another substrate;
• another light-emitting area;
• a second at least one lens element positioned adjacent to the second housing;
• a voltage converter operably coupled to the at least one chip-on-board light-emitting device and the second at least one chip-on-board light-emitting device, and configured to convert a direct current input voltage to a direct current output voltage;
• wherein:
• the at least one chip-on-board light-emitting device is positioned at least partially within the housing and is attached to the housing by one or more fasteners;
• the second at least one chip-on-board light-emitting device is positioned at least partially within the second housing and is attached to the second housing by one or more fasteners;
• the at least one chip-on-board light-emitting device has a power consumption of at least about 50 watts;
• the voltage converter is external to the housing;
• the light-emitting area of the at least one chip-on-board light-emitting device and the another light-emitting area are sealed from the an ambient environment.
