Maintenance Tips
- When servicing a light, replace sealing gaskets as needed—reusing old gaskets is a common cause of leaks and moisture intrusion.
- Keep bonding connections clean and secure; corrosion at bonding points can create reliability and safety issues.
- If you see fogging/water behind the lens or repeated GFCI trips, shut off power and have the light system inspected immediately.
- Maintain balanced water chemistry to reduce corrosion risk on metal components over time.
