1. Introduction
This manual provides essential information for the safe and effective use of your Eiko Q500CL/MC-130V Halogen Bulb. Please read these instructions carefully before installation and operation. This bulb is designed for general illumination purposes, featuring a T-4 shape, E11 screw base, 130V voltage, and 500W wattage.
2. Safety Information
Halogen bulbs operate at high temperatures. Failure to follow these safety guidelines may result in fire, electric shock, or personal injury.
- High Temperature: The bulb and surrounding fixture can become extremely hot during operation and for a period after being turned off. Avoid touching the bulb with bare hands. Allow the bulb to cool completely before handling or replacing.
- Electrical Hazard: Always ensure the power supply to the fixture is turned off before installing, removing, or cleaning the bulb.
- Proper Handling: Do not touch the glass part of the bulb with bare hands. Oils from your skin can create hot spots, leading to premature bulb failure. Use a clean cloth or gloves when handling.
- Voltage Compatibility: Ensure the bulb's voltage (130V) matches the fixture's power supply. Using an incorrect voltage can damage the bulb or fixture.
- Dimmable Use: This bulb is dimmable. Ensure that any dimmer switch used is compatible with halogen bulbs and rated for the bulb's wattage.
- Fixture Compatibility: Use only in fixtures designed for halogen bulbs and rated for the bulb's wattage and dimensions.
3. Setup and Installation
Follow these steps for safe installation of your Eiko Q500CL/MC-130V Halogen Bulb:
- Turn Off Power: Before beginning installation, ensure the power to the light fixture is completely turned off at the circuit breaker or wall switch.
- Allow Cooling: If replacing an existing bulb, allow it to cool down completely before touching it.
- Handle with Care: Using a clean cloth or gloves, carefully remove the new bulb from its packaging. Avoid touching the glass envelope directly.
- Insert Bulb: Gently screw the E11 screw base of the bulb into the compatible socket of your fixture. Do not overtighten.
- Secure Fixture: Ensure the bulb is securely seated in the socket and any fixture covers are properly reinstalled.
- Restore Power: Once installation is complete, restore power to the fixture.

4. Operating Instructions
Operating the Eiko Q500CL/MC-130V Halogen Bulb is straightforward:
- Power On/Off: Use the wall switch or fixture control to turn the light on or off.
- Dimming: If connected to a compatible dimmer switch, adjust the dimmer control to achieve the desired light intensity.
- Initial Use: It is normal for new halogen bulbs to emit a slight odor during their first few hours of operation as manufacturing residues burn off. Ensure adequate ventilation.
5. Maintenance
Proper maintenance ensures optimal performance and longevity of your halogen bulb.
- Cleaning: Only clean the bulb when it is completely cool and the power is off. Use a soft, dry, lint-free cloth to gently wipe away dust or smudges. Do not use liquid cleaners.
- Replacement: When the bulb reaches the end of its life, follow the installation steps in Section 3 to replace it. Always ensure the power is off and the bulb is cool before removal.
- Disposal: Dispose of used halogen bulbs according to local regulations.
6. Troubleshooting
If you encounter issues with your Eiko Q500CL/MC-130V Halogen Bulb, consider the following:
- Bulb Does Not Light:
- Check if the power supply to the fixture is on.
- Ensure the bulb is securely screwed into the socket.
- Inspect the bulb for visible damage (e.g., broken filament). If damaged, replace the bulb.
- Verify the fixture itself is functioning correctly by testing with a known working bulb.
- Bulb Burns Out Quickly:
- Ensure the bulb's voltage (130V) is appropriate for your electrical supply. Using a 120V bulb in a 130V circuit can extend life, but using a 130V bulb in a 120V circuit will not cause premature failure. However, using a bulb with a lower voltage rating than the supply can cause premature failure.
- Avoid touching the glass with bare hands during installation, as skin oils can cause hot spots and reduce bulb life.
- Check for excessive vibration in the fixture, which can damage the filament.
- Ensure the fixture provides adequate ventilation to prevent overheating.
- Dimming Issues:
- Confirm that the dimmer switch is compatible with halogen bulbs and rated for the total wattage of the bulbs connected.
- Ensure the dimmer is properly installed and wired.
