3 Anti-rust & Moisture-proof Tips
I. Introduction: Rainy Season Is a "Test Period" for Outdoor Lights—Anti-rust and Moisture-proof Is Urgent
The high humidity and heavy rainfall environment in the rainy season is the “natural enemy” of outdoor lights. Long-term exposure to rain and moisture, lights are prone to rust, short circuits, dim light and other problems, which not only shorten the service life but also may cause potential safety hazards. In fact, as long as you master the correct anti-rust and moisture-proof skills, you can effectively protect outdoor lights (such as lawn lights, wall lights, ground spike lights, etc.). This blog will share 3 core maintenance skills to help you easily cope with the challenges of the rainy season and keep the lights running stably.
II. Core Skills: 3 Simple and Easy-to-Operate Anti-rust & Moisture-proof Tips
Tip 1: Do a Good Job of Sealing Protection in Advance to Block Moisture Intrusion
Most moisture and rainwater invade through the wiring ports and gaps of the lights. Good sealing is the first line of defense. Operation steps: ① Check the wiring port: If the sealing rubber ring at the wiring is aging or damaged, replace it with a new waterproof rubber ring in time; if there is no rubber ring, wrap 3-5 layers of waterproof tape, then seal it with a waterproof junction box to ensure complete sealing; ② Block the gaps of the light: Use neutral silicone sealant (strong weather resistance, not easy to crack) to block the gaps between the light housing and the lamp pole, base to avoid rainwater infiltration; ③ Special light protection: Apply a layer of anti-rust grease to the connection between the pin and the lamp pole of the ground spike light, which is both sealed and anti-rust; for the power cord interface of the underwater light, reinforce it with a special waterproof connector to avoid water seepage caused by water pressure.
Tips: It is recommended to choose outdoor-specific sealant and waterproof tape, which are resistant to high and low temperatures and aging, and suitable for the complex environment of the rainy season.
Tip 2: Regular Cleaning + Anti-rust Treatment to Extend Service Life
Rainwater in the rainy season carries dust and impurities, which will accelerate corrosion when attached to the surface of the light. Regular cleaning and anti-rust treatment are crucial. ① Cleaning steps: Choose a sunny day to wipe the dust and water stains on the surface of the light with a dry cloth; if the stains are heavy, wipe with diluted neutral detergent (such as dish soap), then dry with a dry cloth to avoid water residue; ② Anti-rust treatment: For metal lights (except aluminum alloy and stainless steel), apply a thin layer of anti-rust spray paint or anti-rust oil on the surface after cleaning, focusing on spraying the bottom of the lamp pole, base and other parts prone to rust; if slight rust is found, first polish off the rust with sandpaper, then perform anti-rust treatment; ③ Notes: Be sure to cut off the power supply during cleaning to avoid electric shock risk; do not directly rinse the light with a high-pressure water gun to prevent damage to the sealing structure.
Tip 3: Reasonably Adjust the Installation Position to Reduce Direct Rain Erosion
If the installation position of the light is easily washed directly by rain, even if the sealing is done well, it will increase the pressure of anti-rust and moisture-proof. You can optimize by adjusting the position or adding protective measures: ① Adjust the installation angle: Tilt the lamp head of the wall light and courtyard light slightly downward (tilt angle 5-10°) to avoid rainwater accumulation on the lamp surface and prevent rainwater from flowing into the lamp body; ② Add shielding devices: Install a small canopy (such as acrylic, stainless steel material) above the light, or use the surrounding eaves and green plants to shield rainwater and reduce direct flushing; ③ Avoid low-lying positions: Do not install ground spike lights and lawn lights in low-lying waterlogged areas of the courtyard; if unavoidable, increase the installation height (such as increasing the length of the lamp pole) to ensure that the lamp body is not soaked by waterlogging.
III. Key Points of Rainy Season Maintenance for Different Types of Lights
Light Type | Maintenance Focus |
|---|---|
Solar Lawn Light | Focus on cleaning the surface of the solar panel to avoid stains blocking and affecting charging; check the sealing of the battery compartment to prevent moisture from damaging the battery |
Outdoor Wall Light | Reinforce the sealing of the wiring port, adjust the tilt angle of the lamp head; regularly check whether the waterproof rubber ring is aging |
Ground Spike Light | Focus on protecting the pin and the bottom of the lamp pole, apply anti-rust grease; avoid installation in waterlogged areas, and check whether there is water accumulation around after rain |
Underwater Light | Check the waterproof connector and sealing rubber ring to ensure no damage; detect the operation status of the light after rain, and cut off the power for maintenance in time if it flickers |
IV. Emergency Treatment: Remedial Measures After Lights Are Damp/Rusted
If you find that the light is damp (such as flickering light, water droplets on the housing) or rusted, take the following measures in time: ① Cut off the power immediately: Avoid short circuit or electric shock risk; ② Drying treatment: Disassemble the light, wipe the surface moisture with a dry cloth, then dry the internal moisture with a hair dryer on low temperature (note not to use high temperature to avoid damaging components); ③ Maintenance and replacement: Check whether the internal components are damaged; if the terminal is rusted or the circuit board is damp, replace or repair it in time; replace all aging sealing components with new waterproof rubber rings and sealant; ④ Reinstallation: After confirming that the light is completely dry and the sealing is intact, reinstall it; observe for 1-2 days after installation to ensure normal operation.
V. Summary
The core of outdoor light maintenance in the rainy season is “prevention first, remediation second”: doing a good job of sealing protection in advance, regular cleaning and anti-rust, and reasonable adjustment of the installation position can effectively block the intrusion of moisture and rainwater and extend the service life of the light. The maintenance focus of different types of lights is slightly different, and you can refer to the targeted suggestions in the article for operation. It is hoped that these 3 simple and practical tips can help you easily protect outdoor lights in the rainy season and make the night lighting stable and safe!
