Introduction
This instruction manual provides essential information for the safe and efficient use of your Philips LED T3 G4 Base Accent Light Bulbs. These 12-volt, non-dimmable LED bulbs are designed for accent and landscape lighting, offering bright white light with significant energy savings. Please read this manual thoroughly before installation and operation.
Important Safety Information
- Electrical Hazard: Always disconnect power before installing, removing, or servicing the bulb. Failure to do so may result in electric shock or damage to the product.
- Voltage Compatibility: These bulbs are designed for 12-volt systems only. Do not use with higher voltage systems (e.g., 120V) as this will damage the bulb and may pose a fire hazard.
- Non-Dimmable: These bulbs are non-dimmable. Do not use with dimmer switches, as this can cause flickering, damage the bulb, or shorten its lifespan.
- Operating Environment: Suitable for both indoor and outdoor use in appropriate G4 fixtures. Ensure fixtures are rated for the intended environment.
- Heat: Although LED bulbs generate less heat than traditional halogens, they still produce some heat. Ensure adequate ventilation around the bulb.
- Disposal: Dispose of bulbs according to local regulations. Philips LED bulbs are mercury-free.
Setup and Installation
Follow these steps to properly install your Philips LED T3 G4 Base Accent Light Bulbs:
- Power Disconnection: Before beginning installation, ensure the power supply to the fixture is completely turned off at the circuit breaker or main switch.
- Remove Old Bulb: Carefully remove the existing bulb from the G4 bi-pin socket. Allow hot bulbs to cool before handling.
- Insert New LED Bulb: Align the two pins of the Philips LED T3 bulb with the holes in the G4 socket. Gently push the bulb straight into the socket until it is firmly seated. Do not force the bulb, as this may bend the pins or damage the socket.
- Secure Fixture: Reassemble any fixture covers or protective elements.
- Restore Power: Once the bulb is securely installed and the fixture is reassembled, restore power to the circuit.

Maintenance
Philips LED T3 bulbs require minimal maintenance:
- Cleaning: Ensure the power is off before cleaning. Gently wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Lifespan: These bulbs have an expected lifespan of 15,000 hours under normal operating conditions. Replacement is typically only necessary after this period or in case of damage.

Troubleshooting
If you encounter issues with your Philips LED T3 bulbs, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up. | No power to the fixture, loose connection, or faulty bulb. | Check power supply at the circuit breaker. Ensure bulb pins are securely seated in the socket. Test with a known working bulb if available. |
| Bulb flickers or blinks. | Incompatible dimmer switch, unstable 12V power supply, or loose connection. | Ensure no dimmer switch is being used (these bulbs are non-dimmable). Verify the 12-volt power supply is stable. Check bulb connection. |
| Bulb is dim or not as bright as expected. | Incorrect voltage, non-dimmable bulb used with a dimmer, or comparison to a higher lumen bulb. | Confirm the fixture provides a stable 12-volt supply. Ensure no dimmer is in use. Note that these bulbs provide 105 lumens. |
