Common symptoms
- One or more fixtures out entirely.
- Dim zones, especially toward the end of a run.
- Lights turning on at the wrong time or not at all.
- Flickering or intermittent operation.
- Corroded, cracked or leaning fixtures.
When repair usually makes sense
- The system is relatively recent and mostly working.
- Problems are isolated to a few fixtures or a specific zone.
- The design still suits your landscape.
When replacement or upgrade is worth considering
- Widespread corrosion or repeated failures.
- An older halogen system with frequent lamp replacement.
- The landscape has changed and the lighting no longer fits it.
- You are planning a significant expansion.
A note on safety
Avoid opening transformers or handling damaged wiring yourself. A qualified professional should diagnose electrical issues.
