- Ventilation Check: Periodically check the radiating and ventilating holes on the top of the fixture to ensure they are free from dust or debris, which could impede heat dissipation.
7. Troubleshooting
- Lamp Not Turning On:
- Check if the power cord is securely plugged into the outlet.
- Ensure the independent switch for that lamp is in the 'ON' position.
- Verify that the bulb is correctly screwed into the socket and is not burnt out. Replace if necessary.
- Fixture Overheating (Red Warning Light):
- Immediately turn off the fixture and allow it to cool.
- Check if the installed bulbs exceed the maximum 150W per socket. Replace with lower wattage bulbs if needed.
- Ensure there is adequate ventilation around the fixture and that the terrarium screen is not blocked.
- Adjust the distance between the fixture and the terrarium if using a lamp stand.
- Inconsistent Temperature:
- Verify that the correct wattage and type of bulbs are being used for your specific reptile's needs and terrarium size.
