Overview #
The Lumishore Underwater Lighting System installed on Ocean Alexander yachts is designed to provide high-performance illumination, durability, and reliable operation in the demanding marine environment.
To maintain optimal light output and maximize service life, routine preventative maintenance is required. Regular inspection and care help prevent premature failures caused by marine growth, corrosion, damaged seals, or electrical issues.
This guide provides general maintenance recommendations and should be used in conjunction with the official Lumishore manufacturer maintenance documentation.
Preventative Maintenance Overview #
Routine maintenance of Lumishore underwater lights should include inspection of:
- Light housings.
- Lens surfaces.
- Mounting areas.
- Sealing components.
- Electrical connections.
- Controllers and power supplies.
Early identification of wear or damage can prevent water intrusion, reduced light output, and system failure.
Light Inspection #
Inspect underwater lights regularly for signs of:
- Physical damage.
- Cracks or deterioration.
- Corrosion.
- Loose mounting hardware.
- Reduced light output.
- Abnormal operation.
Pay particular attention to the lens and light housing, as damage in these areas may allow water intrusion into the fixture.
Lens and Housing Care #
The light lens should be inspected and cleaned periodically to maintain maximum illumination.
Remove:
- Salt buildup.
- Marine growth.
- Algae.
- Debris.
Cleaning recommendations:
- Use only manufacturer-approved cleaning methods.
- Avoid abrasive materials that may scratch the lens surface.
- Do not use harsh chemicals that may damage seals or coatings.
Keeping the lens clean improves light performance and reduces heat buildup caused by restricted light output.
Seal and Gasket Inspection #
The light sealing system protects internal electrical components from the marine environment.
Inspect:
- Gaskets.
- O-rings.
- Sealing surfaces.
Look for:
- Cracking.
- Hardening.
- Deterioration.
- Improper seating.
Damaged sealing components should be replaced promptly to prevent water ingress.
Electrical System Inspection #
Electrical connections should be inspected as part of routine vessel maintenance.
Verify:
- Connections are secure.
- Terminals are clean.
- No corrosion is present.
- Wiring insulation is intact.
- Connections remain protected from moisture.
Corroded or loose connections may cause:
- Intermittent operation.
- Reduced brightness.
- Controller faults.
- Electrical damage.
Controller and Power Supply Checks #
The Lumishore controller and associated power components should be monitored for proper operation.
Check for:
- Proper power delivery.
- Fault indications.
- Communication issues.
- Abnormal behavior.
Address any system alarms or irregular operation promptly.
Preventative Maintenance Recommendations #
For best performance:
- Inspect lights routinely while the vessel is out of the water.
- Clean lenses as required based on operating environment.
- Check seals during haul-out periods.
- Inspect electrical connections periodically.
- Follow Lumishore-approved maintenance procedures.
- Use only compatible cleaning products and protective coatings.
Important Notes #
Underwater lighting systems operate in one of the harshest marine environments. Saltwater exposure, marine growth, and electrical connections require regular attention to maintain reliable operation.
Proper preventative maintenance helps:
- Extend fixture life.
- Maintain light intensity.
- Prevent water intrusion.
- Reduce unexpected failures.
