Safety Information
Always observe the following safety precautions:
- Ensure power is turned OFF at the main circuit breaker before installing or removing the bulb.
- Do not handle the bulb with wet hands.
- Do not attempt to disassemble or modify the bulb.
- Dispose of used fluorescent bulbs according to local regulations, as they contain small amounts of mercury. Do not dispose of in regular household waste.
- Avoid direct eye exposure to the light source for prolonged periods.
- Use only in fixtures designed for T8 fluorescent tubes with a G13 bi-pin base and appropriate ballast.
Setup and Installation
Follow these steps for proper installation:
- Power Off: Locate the circuit breaker controlling the light fixture and switch it to the OFF position. Verify that the power is off by attempting to turn on the light.
- Remove Old Bulb (if applicable): Carefully twist the old fluorescent tube 90 degrees to align the pins with the slots in the fixture's lampholders, then gently pull it out.
- Insert New Bulb: Align the two pins on each end of the new OSRAM T8 fluorescent tube with the slots in the lampholders. Insert the pins fully into the slots.
- Secure Bulb: Once the pins are fully inserted, rotate the tube 90 degrees until it clicks securely into place. The tube should feel firm and not wobble.
- Restore Power: Return to the circuit breaker and switch the power back ON.
- Test: Turn on the light switch to confirm the bulb is working correctly.
Note: If the bulb does not light up, ensure it is properly seated in the lampholders and that the ballast in the fixture is functioning correctly.
