Safety Information
Always observe the following safety precautions:
- Risk of Burns: Halogen bulbs operate at high temperatures. Do not touch the bulb directly during operation or immediately after turning off. Allow sufficient time for cooling.
- Electrical Hazard: Ensure power is disconnected before installing, removing, or handling the bulb.
- Correct Voltage: Use only with 12V power supplies. Using incorrect voltage can damage the bulb and fixture.
- Handle with Care: Avoid touching the glass envelope of the bulb with bare hands. Oils from skin can create hot spots, reducing bulb life. Use a clean cloth or gloves during installation.
- Proper Fixture: Install only in fixtures designed for G4 bi-pin halogen bulbs with appropriate wattage ratings.
- Disposal: Dispose of used bulbs according to local regulations.
Setup and Installation
- Power Disconnection: Before beginning, ensure the power supply to the fixture is completely turned off at the circuit breaker or wall switch.
- Old Bulb Removal (if applicable): If replacing an existing bulb, allow it to cool completely. Gently pull the old bulb straight out from its socket.
- New Bulb Handling: Hold the new OSRAM 64258 HLX bulb by its ceramic base or with a clean, lint-free cloth or gloves. Avoid touching the glass envelope directly.
- Insertion: Align the two pins of the G4 base with the holes in the fixture's socket. Gently push the bulb straight into the socket until it is fully seated. Do not force it.
- Power Connection: Once the bulb is securely installed, restore power to the fixture.
