Setup and Installation
- Turn Off Power: Locate the light fixture's power switch and turn it to the OFF position. For added safety, turn off the circuit breaker supplying power to the fixture.
- Remove Old Bulb (if applicable): If replacing an existing bulb, allow it to cool completely. Gently pull the old G4 pin-base bulb straight out from its socket. Do not twist.
- Handle New Bulb: Carefully remove the new OSRAM Halostar Starlite bulb from its packaging. Avoid touching the glass envelope with bare hands. Use a clean, lint-free cloth or gloves to hold the bulb by its ceramic base or pins.
- Insert New Bulb: Align the two pins of the new bulb with the holes in the G4 socket. Gently push the bulb straight into the socket until it is fully seated. Do not force the bulb.
- Restore Power: Once the bulb is securely installed, turn the circuit breaker back on, then turn the light fixture's switch to the ON position.
Operating Instructions
After successful installation, simply turn on the power switch connected to the light fixture. The OSRAM Halostar Starlite bulb will illuminate instantly, providing its intended light output.
Maintenance
Halogen bulbs generally require minimal maintenance. The primary maintenance task is bulb replacement when it reaches the end of its operational life.
- Cleaning: If the bulb's glass becomes dusty, ensure the power is off and the bulb is cool. Gently wipe the glass with a clean, dry, lint-free cloth. Do not use liquid cleaners.
- Replacement: When the bulb burns out, follow the installation steps to safely replace it with a new OSRAM Halostar Starlite G4 10W 12V bulb.
Troubleshooting
- Bulb Does Not Light:
- Check if the power switch is ON.
- Verify that the circuit breaker is not tripped.
- Ensure the bulb is fully and correctly seated in the socket.
- If the bulb is old, it may have reached the end of its life and requires replacement.
- Confirm the fixture is supplying the correct 12V to the bulb.
- Bulb Flickers:
- Check for loose connections in the socket or fixture.
- Ensure the bulb is fully seated.
- Flickering can sometimes indicate an aging bulb or an issue with the power supply/transformer.
