- Insert New Tube: Align the two pins on each end of the SYLVANIA F6T5/CW tube with the slots in the fixture's sockets. Gently push the tube into the sockets until the pins are fully seated.
- Rotate Tube: Once seated, rotate the tube 90 degrees until it locks into place. Ensure it is securely held by both sockets.
- Restore Power: Turn the power back on at the circuit breaker or wall switch.
