Marine lighting systems include navigational lights, underwater lights, flood lights, courtesy lights, accent lights, dome lights and down lights, compartment and utility lights, reading or berth lights, area lights, docking lights, and marine safety lighting equipment that includes searchlights, spotlights, beacons and signal lights. These lights are used on recreational and commercial vessels including cargo carrying vessels, commercial fishing boats, passenger and vehicle ferries, tankers, offshore oil and gas drilling and production platforms, floating production storage and offloading (FPSO) vessels, fishing boats, cruise ships, luxury pleasure yachts, pontoon boats, patrol boats, and pilot boats, etc. Marine lighting products are designed to stands up to the harshest marine environments which may expose a lighting system to salt air corrosion, vapor or water penetration, flammable or explosive gases, high winds, and other operational stresses. With loads of features such as longer life, lower battery drain, no ballasts needed, lower power consumption per lumen output, resistance to vibration, and low maintenance, marine-grade LED luminaries and light fixtures provide a competitive edge over conventional lighting, including that of halogen, incandescent, metal halide, or fluorescent light sources.
