Pentair Pentair IntelliBrite 5G LED Pool/Spa Light NO LIGHT Error Fix: Light Not Illuminating

Error code NO LIGHT on the Pentair Pentair IntelliBrite 5G LED Pool/Spa Light means: Light Not Illuminating. The IntelliBrite light does not turn on at all. Check the circuit breaker or automation relay controlling the light circuit. Verify voltage at the light niche junction box with a multimeter. If voltage is present but the light does not illuminate, the LED lamp has failed and needs replacement. Check for water inside the fixture — a flooded fixture will short the lamp. For underwater lights, the fixture must be pulled from the niche (the light cord has enough slack to bring the fixture to the pool deck) for lamp inspection and replacement.
