Underwater Lights

Adding underwater lighting requires planning to prevent corrosion or water ingress. At Nautiba we assess component integrity: a light fitting must have IP68 protection to withstand constant pressure. Always check that the body is made of AISI 316, essential for preventing galvanic corrosion in salt water. Installing these lights means drilling through the hull, an operation that leaves no room for error. Verify the mounting type, recessed or surface-mount, and make sure the insulation between the light body and the hull is effective to avoid stray currents. Fiberglass requires different precautions compared to aluminum or steel; using appropriate marine gaskets and sealants is an integral part of the job. If you have doubts about the power draw or compatibility with a 12V or 24V system, do not proceed based on aesthetics alone. We will go through the specifications with you to avoid impossible installations. Our priority is to provide you with the data needed for work that lasts, preventing a rushed choice from becoming a watertight integrity problem.

Criteria for an informed choice

When selecting an underwater light, keep these technical aspects in mind: verify the IP protection rating, which must be IP68 for continuous immersion. Check material compatibility with the hull: AISI 316 is the standard to prevent corrosion at sea. Consider electrical draw: verify that your system and existing cable gauge are adequate for the load to avoid voltage drop. Assess the mounting method: a hole in the hull is a critical point, make sure you have the internal space needed for cabling and secure fastening. AISI 316 stainless steel is the correct choice for its corrosion resistance, thanks to the molybdenum content that makes it stable in a salt environment. An IP68 rating means the device is protected against dust and can be permanently submerged to a depth defined by the manufacturer. On metal hulls, electrical insulation is mandatory to prevent the light from becoming part of the galvanic circuit, causing accelerated corrosion. Always verify your system voltage: if you have a 24V system, make sure the driver is compatible, as a voltage mismatch would immediately damage the LEDs.

What does IP68 protection mean?

It means the device is fully protected against dust and can be permanently submerged in water to a depth defined by the manufacturer, guaranteeing a watertight seal.

Is it necessary to electrically isolate the light from the hull?

Yes, especially on metal hulls, to prevent the light from becoming part of the galvanic circuit, causing accelerated corrosion on the hull bottom or on the component itself.

How do I choose the correct voltage for the lights?

Always check your onboard system voltage. If you have a 24V system, make sure the driver or the light itself is compatible, as a voltage mismatch would immediately damage the LEDs.
