Safety Information
Please read and understand all safety warnings before installing or operating this lamp. Failure to follow these instructions may result in electric shock, fire, personal injury, or property damage.
- WARNING: Risk of Electric Shock. Always disconnect power at the circuit breaker or fuse box before installing, removing, or servicing the lamp.
- WARNING: Risk of Fire. Use only in fixtures specifically designed for metal halide lamps and with the appropriate M98 ANSI code ballast. Ensure the fixture's wattage rating is not exceeded.
- WARNING: Risk of Burns. Metal halide lamps operate at high temperatures. Allow the lamp to cool completely before handling. Do not touch the lamp with bare hands during operation or immediately after shutdown.
- Do not use if the outer glass envelope is broken, cracked, or scratched. Such damage can lead to lamp rupture.
- Ensure the lamp is securely screwed into the socket to prevent arcing or poor contact.
- Dispose of lamps according to local regulations, as they may contain mercury.

Setup and Installation
Follow these steps carefully to install your Sunlite Metal Halide Lamp:
- Power Disconnection: Ensure the power supply to the fixture is completely disconnected at the circuit breaker or fuse box before starting installation.
- Fixture Compatibility: Verify that your lighting fixture is designed for metal halide lamps and is compatible with an E26 medium base and M98 ANSI code ballast. Refer to your fixture's manual for compatibility information.
- Lamp Inspection: Carefully remove the new lamp from its packaging. Inspect the lamp for any signs of damage, such as cracks or chips in the glass. Do not install a damaged lamp.
- Installation: Gently screw the lamp into the fixture's E26 socket. Turn clockwise until it is snug. Do not overtighten, as this can damage the lamp or socket.
- Secure Seating: Ensure the lamp is securely seated in the socket.
- Restore Power: Once the lamp is properly installed, restore power to the fixture.
Operating Instructions
After successful installation and power restoration, the lamp will begin its operation sequence:
- Initial Ignition: Upon power-up, the pulse start mechanism will ignite the lamp.
- Warm-up Period: Metal halide lamps require a short warm-up period to reach full brightness and stable color output. This typically takes a few minutes.
- Hot Restart: If the lamp is turned off, it will require a cool-down period before it can be restarted. Attempting to restart a hot metal halide lamp immediately will prevent it from igniting until it has cooled sufficiently. This is a normal characteristic of HID lamps.
Maintenance
Proper maintenance ensures optimal performance and extends the life of your lamp.
- Cleaning: Periodically clean the outer surface of the lamp with a soft, dry, lint-free cloth. Do not use liquid cleaners, abrasives, or solvents, as these can damage the lamp or leave residues that affect light output.
- Inspection: Regularly inspect the lamp and fixture for any signs of damage, corrosion, or loose connections. Address any issues promptly.
- Lamp Replacement: Replace the lamp when it reaches its average rated life (15,000 hours) or if you observe significant dimming, flickering, or cycling (turning on and off repeatedly).
- Safety First: Always disconnect power to the fixture and allow the lamp to cool completely before performing any cleaning or inspection.
Troubleshooting
If you encounter issues with your Sunlite Metal Halide Lamp, refer to the following troubleshooting guide:
- Lamp Does Not Light:
- Check if the power supply to the fixture is active.
- Ensure the lamp is securely screwed into the socket.
- Verify that the ballast is compatible (M98 ANSI code) and functioning correctly.
- Inspect the lamp for any visible damage to the filament or outer envelope. Replace if damaged.
- Lamp Flickers or Cycles (Turns On and Off Repeatedly):
- This often indicates the lamp is nearing its end of life. Replace the lamp.
- It could also be a sign of an incompatible or failing ballast. Consult a qualified electrician if replacing the lamp does not resolve the issue.
- Ensure the ambient temperature is within the operating range for the lamp and fixture.
- Reduced Brightness or Color Shift:
- Clean the lamp's outer surface as described in the Maintenance section.
- Reduced brightness is a natural occurrence as the lamp ages. Consider replacing the lamp if output is significantly diminished.
