2. Setup and Installation
Follow these steps to safely install your G4LED-20-W lamp:
- Safety First: Before attempting any installation, ensure the power supply to the lighting fixture is completely turned off at the circuit breaker or transformer.
- Remove Old Lamp: Carefully remove the existing lamp from the G4 base socket. Allow it to cool if it was recently in use.
- Insert New Lamp: Align the two pins of the G4LED-20-W lamp with the holes in the G4 base socket. Gently push the lamp straight into the socket until it is fully seated. Avoid bending the pins during insertion.
- Secure Fixture: Reassemble any fixture components that were removed for lamp access.
- Restore Power: Turn the power supply back on. The lamp should illuminate.
Important: This lamp is designed for low-voltage (10-15V) systems only. Do not use it with standard line voltage (120V/240V) fixtures.
3. Operating Instructions
The FX Luminaire G4LED-20-W lamp operates automatically once properly installed in a compatible low-voltage lighting system. When power is supplied to the fixture, the lamp will turn on. When power is removed, the lamp will turn off. No special operating procedures are required for the lamp itself.
- Ensure your low-voltage transformer is functioning correctly and providing power within the 10-15V range.
- The lamp provides instant full brightness upon activation.
4. Maintenance
The G4LED-20-W lamp is designed for minimal maintenance due to its long lifespan and durable construction.
- Cleaning: If the lamp becomes dirty, gently wipe the silicone capsule with a soft, dry, or slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Handling: While the silicone encapsulation provides protection, avoid excessive bending or forceful handling of the lamp, especially the pins, as this can cause damage.
- Replacement: With an average lifespan of 33,000 hours, frequent replacement is not anticipated. Replace the lamp only when it ceases to function.
5. Troubleshooting
If your G4LED-20-W lamp is not functioning as expected, consider the following:
- Lamp Not Illuminating:
- Check Power: Ensure the power supply to the fixture is on and the transformer is working correctly.
- Verify Voltage: Confirm that the fixture is receiving 10-15V. Incorrect voltage can prevent the lamp from working or damage it.
- Proper Seating: Remove the lamp and re-insert it firmly into the G4 socket to ensure good electrical contact.
- Fixture Compatibility: Ensure the fixture is designed for G4 base, low-voltage lamps.
- Lamp Damage: Inspect the lamp for any visible damage, such as bent pins or cracks in the silicone. If damaged, replace the lamp.
- Flickering Light:
- Voltage Fluctuations: Check the stability of your low-voltage power supply.
- Loose Connection: Re-seat the lamp in the socket.
If troubleshooting steps do not resolve the issue, contact customer support or a qualified electrician.
