Setup and Installation
- Power Off: Before beginning installation, ensure the power supply to the lighting fixture is completely turned off at the circuit breaker or fuse box. Verify that the fixture is de-energized.
- Remove Old Tube (if applicable): If replacing an existing tube, carefully twist the old tube approximately 90 degrees and gently pull it out of the fixture's lampholders.
- Inspect Fixture: Check the fixture's lampholders for any damage or corrosion. Ensure they are clean and in good working condition.
- Insert New Tube: Align the two pins on each end of the SYLVANIA F8T5/WW tube with the slots in the fixture's lampholders. Gently push the tube into the lampholders until the pins are fully seated.
- Secure Tube: Once the pins are seated, rotate the tube approximately 90 degrees until it locks securely into place. Do not force the tube.
- Restore Power: Once the tube is securely installed, restore power to the fixture at the circuit breaker or fuse box.
- Test: Turn on the light switch to confirm proper operation of the new fluorescent tube.
Operating Instructions

Maintenance
- Cleaning: To clean the fluorescent tube, ensure the power is off and the tube is cool. Gently wipe the tube with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials, as these can damage the tube's coating.
- Replacement: Replace the tube when it reaches the end of its life, indicated by flickering, dimming, or failure to light. Follow the installation steps in reverse to remove the old tube and then install a new one.
