Safety Information
Always turn off power at the circuit breaker before installing or removing fluorescent lamps. Handle lamps by the ends to avoid damaging the glass or internal components. Do not use in dimming circuits unless specifically rated for dimmable fluorescent lamps and compatible ballasts. Dispose of lamps according to local regulations, as they contain small amounts of mercury.
Setup and Installation
- Power Disconnection: Before beginning installation, ensure the power to the fixture is completely turned off at the circuit breaker or fuse box. Verify power is off using a voltage tester.
- Remove Old Lamp (if applicable): Carefully twist the old fluorescent tube 90 degrees to align the pins with the slots in the lampholders. Gently pull the lamp straight out from the fixture.
- Inspect Fixture: Check the lampholders for any damage or corrosion. Ensure they are clean and in good working order. Confirm the fixture uses a compatible T8 ballast (Rapid Start or Instant Start).
- Install New Lamp: Hold the new SYLVANIA T8 lamp by its ends. Align the pins on both ends of the lamp with the slots in the lampholders. Gently push the lamp into the lampholders until the pins are fully seated.
- Secure Lamp: Rotate the lamp 90 degrees until it locks securely into place. The lamp should feel firm and not wobble.
- Restore Power: Once the lamp is securely installed, restore power to the fixture at the circuit breaker.
- Test Operation: Turn on the light switch to confirm the lamp illuminates properly.

Operating Instructions
SYLVANIA T8 Octron Fluorescent Ecologic Lamps are designed for straightforward operation in compatible fluorescent fixtures. Once installed, simply activate the light switch connected to the fixture. The lamp will illuminate rapidly, providing consistent, high-quality light.
- Ensure the fixture's ballast is compatible with T8 fluorescent lamps for optimal performance and lamp life.
- Avoid frequent on/off cycling, as this can reduce the lamp's lifespan.

Maintenance
Minimal maintenance is required for your SYLVANIA T8 fluorescent lamp. Regular cleaning and proper handling will help ensure its long-term performance.
- Cleaning: Periodically, with the power off and the lamp cool, gently wipe the lamp surface with a soft, dry, lint-free cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
- Lamp Replacement: Replace lamps when they begin to flicker, dim significantly, or fail to illuminate. Always replace with a lamp of the same type and wattage for consistent light output and compatibility with the existing ballast.
- Fixture Inspection: Annually inspect the fixture wiring and lampholders for any signs of wear, damage, or loose connections.
