Why Terex Flood Light arc tube is discolored or swollen?
- SSheila NelsonSep 12, 2025
If the Terex Flood Light arc tube is discolored or swollen, it may be due to over voltage from the power supply. Check the voltage at the ballast for current or voltage surges, and inspect for shorted capacitors, replacing as needed. Another potential cause is an improper ballast, so check the ballast name plate against the lamp data.
