Impact On Pool Lighting

Why Jandy Pool Lights Fail
Jandy pool lights can stop working for different reasons. Knowing why they fail helps you fix them faster. These lights face many challenges because they stay underwater and exposed to weather. Understanding the common causes of failure can save money and time.
Typical Causes
Jandy pool lights often fail due to wear and tear. Over time, seals and parts break down. Dirt and debris can block the light or damage parts. Regular use in water weakens materials, causing failure. Spotting problems early prevents bigger issues.

Labor Charges
