Corrosion Protection for Outdoor lights

Why is corrosion protection important for outdoor lights?

Outdoor lights are continually exposed to humidity, pollution, salt spray, and temperature changes, all of which accelerate corrosion. Proper corrosion protection ensures safety, maintains performance, and reduces ongoing maintenance costs

Which standards define corrosion categories for outdoor lighting?

Corrosion categories for lighting are defined by ISO 12944 and ISO 9223. These standards classify atmospheric corrosivity and outline appropriate protective measures.

What corrosion categories are commonly used?

• C3: Medium pollution or low salt exposure in temperate areas

• C4: High pollution industrial or coastal environments

• C5: Very high pollution with significant salt spray

What are the benefits of using corrosion-protected luminaires?

• Longer service life

• Reduced maintenance and replacement costs

• Improved safety and compliance

• Consistent lighting performance and appearance

Which enLighten luminaires fit each corrosion category?

• C3: Urban, low-chloride coastal, moderate pollution:
  Tauro Black, Kascade, Noctua, Yindi, Supernova, Wall Light

• C4: Industrial or high-pollution urban areas:
  Zorro 2, High Powered Floodlight SF484

• C5: Very high pollution and heavy salt exposure:
  High Powered Floodlight SF257

How is the Zorro 2 streetlight protected from corrosion?

The Zorro 2 Streetlight is rated C4 and protected with a two-stage coating system:

• Electrophoretic coating: for a uniform, moisture-resistant base layer

• Powder coating: for a durable cured finish
