Troubleshooting

Light is dim or flickering

Check supply voltage matches the LED module rating. Low voltage causes dimming. If voltage is correct, the LED module is failing — replace it. LED modules have finite life (typically 50K-100K hours).

Light doesn't turn on

Verify voltage at the terminals with a multimeter. Check the PLC output or relay driving the light. LED modules are polarity-sensitive on DC circuits — try reversing the leads.
