1. the lamp’s casing material

Not all metals corrode severely when exposed to airborne saltwater moisture. Aluminum, for example, does not corrode. because it has the ability to react with oxygen in the air and create alumina on its surface.

The alumina on the surface may separate the water and oxygen in the air, keeping the inner aluminum material from reacting further, assuring the material’s anti-corrosion and durability. Additionally, aluminum has high thermal conductivity, allowing for rapid heat disposal.

Additionally, this performance is ideal for those high-power bulbs utilized in huge container wharves. As a result, metallic aluminum makes an excellent shell material for beach lights and lanterns.

2. the treatment of the housing material’s surface

Another efficient means of preventing corrosion is coating. Coatings may isolate the surface of the base material from the electrochemical corrosion affecting elements and produce a protective layer on the substance’s surface.

When choosing bulbs for maritime environmental lighting projects, extra consideration should be given to the light fixture’s base material and whether it is covered by a coating. Because they are relevant to the average service life of naval lighting equipment.

3. the luminaire structure’s IP rating

Marine ambient lighting fixtures are continually exposed to wet salty air for an extended period of time. If the light lacks an adequate waterproof rating. Seawater molecules in the air quickly permeate the lamp’s core. While LEDs are a fragile kind of semiconductor component. If saltwater penetrates, a moisture absorption phenomenon occurs on the chips, causing damage to the LEDs, PCB, and other components, as well as corroding the internal components.

As a result, the waterproofing of lights is crucial. A high IP certification ensures the lighting fixture’s long-term, steady, and regular operation at the beach.

4. the substance used to plug the pressure vent

Generally, exterior luminaires such as LED street lights and LED flood lights generate a significant amount of heat after being illuminated for an extended length of time. This heat causes the inside air to expand, forcing the air out of the bulb.

On the contrary, when lights are switched off and allowed to cool, a suction is formed within the lamp, which draws in exterior air, water vapor, and dust. To address this issue without jeopardizing the lights’ waterproof properties, these outdoor luminaires are often equipped with pressure vents. Where there is a vent, an appropriate gland for waterproofing treatment must be used.

If the size and substance of the gland size material do not satisfy the applicable standards, the lamp’s tightness will be lowered as well. When they operate in a maritime setting, the chance of bulbs being percolated by the saltwater vapor is increased. If not properly maintained, this invisible pressure vent might become a major concern.

4. salt spray test report of the luminaire

The salt spray test is a critical experiment for determining a product’s corrosion resistance. The findings demonstrate the lights’ corrosion resistance. When choosing lamps for coastal lighting projects, the salt spray test report may be utilized as a reference standard.
