4. Operation

After successful installation, turn on the power to the fixture. The lamp should illuminate immediately. If the fixture is connected to a compatible dimmer, you can adjust the light output within the 3-100% dimming range.

Allow a short warm-up period for the lamp to reach full brightness and stable color temperature, which is typical for fluorescent technology.

5. Maintenance

• Cleaning: To clean the lamp, ensure the power is off and the lamp has cooled. Use a soft, dry, lint-free cloth to gently wipe the glass. Do not use liquid cleaners or abrasive materials.
• Replacement: Replace the lamp when it reaches the end of its operational life, indicated by flickering, dimming, or failure to ignite. Follow the installation steps for replacement.

6. Troubleshooting

• Lamp Does Not Light:
  • Check if the power supply to the fixture is on.
  • Ensure the lamp is correctly and securely seated in the socket.
  • Verify that the fixture's ballast (electronic control gear) is functioning correctly and is compatible with a 26-watt G24q-3 CFL.
  • Test with a known working lamp if available.
• Lamp Flickers or Dims:
  • This may indicate the lamp is nearing the end of its operational life.
  • Ensure the dimmer switch (if used) is compatible with dimmable CFLs and is functioning correctly.
  • Check for loose connections in the fixture.
• Lamp Emits Unusual Noise:
