Please read these instructions thoroughly before installation and operation.
2. Safety Information
WARNING: Metal Halide lamps operate at high temperatures and pressures. Failure to follow these safety instructions may result in personal injury, property damage, or reduced lamp life.
- Professional Installation Recommended: Due to the high wattage and specific electrical requirements, installation should be performed by a qualified electrician.
- Proper Ballast Required: This lamp requires a compatible 1000 Watt Metal Halide ballast (ANSI M47/S). Do not operate without the correct ballast.
- Fixture Compatibility: Ensure the fixture is rated for 1000 Watt Metal Halide lamps and has a Mogul E39 base.
- Eye Protection: Avoid direct exposure to the lamp's light output, especially during operation, as it can be extremely bright.
- Thermal Shock: Do not operate lamps in fixtures where water can come into contact with the hot lamp.
- Lamp Disposal: Dispose of lamps according to local regulations. Metal halide lamps contain mercury.
- Unprotected Arc Tube: This lamp features an unprotected arc tube. It must be used in an enclosed fixture to prevent injury from potential arc tube rupture.

4. Setup and Installation
- Power Off: Ensure the power to the fixture is completely turned off at the circuit breaker before beginning installation.
- Allow Cooling: If replacing an existing lamp, allow the old lamp and fixture to cool completely before handling.
- Inspect Fixture: Verify that the fixture is clean, dry, and free from damage. Confirm it is rated for a 1000 Watt Metal Halide lamp and has a Mogul E39 socket.
- Handle with Care: Hold the new lamp by its base or envelope, avoiding contact with the arc tube. Do not drop or subject the lamp to impact.
- Screw In Lamp: Carefully screw the Mogul E39 base of the SYLVANIA 64468 bulb into the fixture's socket until it is finger-tight. Do not overtighten.
- Enclosed Fixture: Confirm the lamp is installed in an appropriate enclosed fixture, as this lamp has an unprotected arc tube.
- Power On: Once securely installed, restore power to the fixture.
5. Operating Instructions
- Warm-up Time: Metal Halide lamps require a warm-up period to reach full brightness and color stability. This typically takes several minutes.
- Restrike Time: If the lamp is turned off, it will require a cool-down period (typically 5-15 minutes) before it can be reignited. Attempting to restrike a hot lamp too soon may prevent it from lighting or reduce its lifespan.
- Universal Burn Position: This lamp is designed for universal burn, meaning it can be operated in any position (horizontal, vertical, or angled) without affecting performance or lifespan.
6. Maintenance
- Cleaning: Periodically clean the outer glass envelope of the lamp and the fixture reflector with a soft, dry cloth to maintain optimal light output. Ensure the lamp is cool and power is off before cleaning.
- Replacement: Replace the lamp when it reaches its end of life (indicated by dimming, flickering, or failure to ignite) or if the outer envelope is cracked or damaged. Always replace with a lamp of the same wattage and type (ANSI M47/S).
- Ballast Check: If a lamp fails prematurely, inspect the ballast for proper operation. A faulty ballast can damage lamps.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lamp does not light. | No power to fixture, incorrect ballast, loose connection, faulty lamp, lamp not cooled down for restrike. | Check power supply. Verify ballast compatibility. Tighten lamp in socket. Allow cool-down if recently turned off. Replace lamp if faulty. Consult an electrician for ballast issues. |
| Lamp flickers or cycles on/off. | End of lamp life, incorrect ballast, voltage fluctuations, overheating. | Replace lamp. Verify ballast compatibility. Check power supply for stability. Ensure proper ventilation for the fixture. |
| Reduced light output. | End of lamp life, dirty lamp/reflector, incorrect ballast. | Replace lamp. Clean lamp and reflector. Verify ballast compatibility. |
