• Dispose of used fluorescent bulbs according to local regulations, as they may contain small amounts of mercury.

Setup and Installation

Follow these steps to properly install your OSRAM L 8W/840 T5 Fluorescent Tube Light Bulb:

1. Power Off: Before beginning, ensure the power supply to the light fixture is completely turned off at the circuit breaker or switch.

3. Insert New Bulb: Align the bi-pin connectors of the new OSRAM L 8W/840 bulb with the sockets in the fixture. Gently push the bulb into the sockets until it is fully seated.
4. Secure Bulb: Once inserted, rotate the fluorescent tube approximately a quarter turn (either clockwise or counter-clockwise) until it locks securely into place. You may need to apply slight force to ensure it is properly seated and connected.
5. Restore Power: After the bulb is securely installed, restore power to the fixture.
6. Test: Turn on the light switch to confirm the bulb is functioning correctly.

Note: If the bulb does not light up, ensure it is properly seated and rotated into the sockets. If issues persist, refer to the Troubleshooting section.
