The beauty of the shoreline and the safety of pedestrians both depend on outdoor coastal lights. Outdoor coastal lighting fixtures, however, differ greatly from other types of public lighting. The pavement needs enough illumination at night, as well as the port and harbor along the coastline. Additionally, the particularity of the lights in coastal places is enhanced by the salty and moist environment. It implies that coastal lighting must be waterproof and anti-corrosive.

The majority of people are only aware that coastal lights are susceptible to rust and have no other knowledge of the coastal environment or how the lights resist tough conditions. This article will discuss the interactions between outdoor lighting and the coastal environment, as well as how to mitigate any harmful consequences.

What impact does the coastal environment have on lights?

Lights are at a heightened risk of corrosion and rust in coastal environments because of the sea salt and moisture present. As is common knowledge, freshwater rusts metal and electronic components more slowly than salt water. Because salt has a higher conductivity, the process moves more quickly. The wind disperses the sea salt, which is airborne, broadly. Salinity is higher in coastal environments than in other places. The catalyst for light rust and corrosion is the moisture and salt in the air. Performance changes and breakdowns happen more frequently. Lighting in coastal environments is therefore more prone to rust and corrosion. Extreme weather, which could include strong gusts and heavy rain, makes the situation even worse. Extreme weather puts more strain on lights, hastening their failure. In a coastal setting, not all lights corrode and rust at the same rate. Wind speed, wave height, distance from lights to shoreline, material of lights, etc. all affect how quickly lights corrode and rust. In addition, lights will inevitably rust and corrode. Every effort is made to slow down corrosion and increase the lifespan of lights.

How do outdoor lights withstand the corrosive coastal environment?

The main hazards to lighting performance in coastal environments are damp and salt. Two major approaches are used to enable lights to endure the harsh coastal environment. One is to shield dangerous elements from lighting, and the other is to fortify defenses against salty and damp air.

Obstruct the lights’ threat-causing elements

Finishing and coating are used to shield lights from moisture and salty air, preventing corrosion and rust. Lighting is also made more robust by coating and finishing. Metal components are frequently coated using electrophoretic coating and powder coating. These painting techniques attempt to increase corrosion resistance and longevity. For metal components, electrophoretic coating is typically considered the first painting procedure. The heat and UV light resistance is provided through powder coating. Lights are double protected by electrophoretic coating in conjunction with powder coating. Rust and corrosion, however, are unavoidable. There is still very little reaction between the finishing and coasting surface and oxygen and water.

Bolster the ability to withstand salty and wet air

The material of lights has a significant impact on their resistance to damp and salty air. Corrosion and rust are actively facilitated by the active reactions of zinc, copper, and steel with oxygen and water. Despite being more affordable, they cannot be used as the material for coastal lights. Stainless steel, in comparison, is more stable than older metals. However, it is pricey and out of reach for the majority of people. The most frequently utilized material for coastal lighting is aluminum. Ingress protection and corrosion prevention are both accomplished with aluminum. Additionally, it is economical.

Lights are put through a 1000-hour salt spray test to make sure they are durable. After the test, pitting, deterioration, cracking, or other problems are not permitted. This test is essential to ensuring that lights operate steadily in coastal environments. But the actual circumstances are worse. Product quality is important to Yibai LED Lighting. Before delivery, the Nova series anti-corrosion flood light passed a 1,500-hour salt sprat test. ensuring optimum performance and stability in the products.

What impact do lights have on the coastal environment?

Coastal lights obviously play a significant role in improving pedestrian visibility and beautifying the coastline. An inviting mood is created by bright, comfortable lighting. People walking along the seaside unwind and take in the stunning landscape. Additionally, coastal lights help to increase public safety and lower crime. Accidents are less likely to happen at night since the environment and onlookers are visible. However, it is not a given that lighting is always advantageous to the coastal environment. The coastal environment is home to not only humans but also to numerous animals and plants. It’s important to remember that compared to people, plants and animals are more sensitive to artificial light. When it comes to light, what is adequate for us could be too much for plants and animals. For instance, lights that are close to the shoreline generate light and trespass into sea turtle habitats, upsetting their pattern and causing chaos. Sky shine, or light pollution, is another issue that affects the environment. Skylight can harm or even kill birds that dwell near and along the coast.

How to avoid causing light pollution in coastal areas

Using full cutoff lights, keeping lights away from the shore, and limiting light intensity and number are the three approaches to prevent light pollution in coastal environments. Since most animals are more sensitive to light than humans, lowering the intensity and number of lights can help reduce the intrusion of light into animal habitats to some extent. However, a decrease in the number of lights or the intensity of the light does not equate to a drop in the minimal degree of safety. Keeping lights off the shore is a more effective strategy to prevent harm to marine life. It implies that great planning should go into the lighting arrangement. The light that is dispersed widely may end up on the shore and in the water. Repositioning the current lights to minimize light pollution to coastal species is preferable. Full cutoff and totally shielded lights must be used to prevent sky glow. The shields prevent spill light from passing through, so only downward lighting is allowed. The pavement, boardwalks, and roads should be the only things illuminated by the descending light. Otherwise, the light will disperse and interfere with how coastal species normally behave.


For outdoor lights, the unique coastal climate of moisture and salt presents a significant difficulty. Lights are more prone to rust and corrosion. Stable material, finishing, and coasting are outfitted for the lights in order to withstand the severe coastal climate. Walking at night is made more pleasant for pedestrians by adequate lighting. Additionally, it enhances public safety. However, it is best to avoid light pollution that invades the sky and the habitat of other organisms. While using entirely cutoff and fully covered lights, lights must be kept away from the beach.
