Setup and Installation
Philips LED InstantFit T8 Tube Light Bulbs are designed for easy replacement of existing fluorescent T8 tubes. They are compatible with most instant start electronic ballasts, eliminating the need for complex wiring installations.
Installation Steps:
- Safety First: Before beginning installation, ensure the power to the light fixture is turned off at the circuit breaker to prevent electrical shock.
- Remove Old Tubes: Carefully remove the existing fluorescent T8 tubes from the fixture. Handle with care as they may contain mercury.
- Insert New LED Tubes: Align the bi-pin base of the Philips LED InstantFit T8 tube with the sockets in the fixture. Gently push and twist the tube until it is securely seated.
- Verify Compatibility: While these bulbs are designed for broad compatibility, always ensure your fixture's ballast is an instant start electronic type for optimal performance. Refer to the compatibility chart in the product images for guidance.
- Restore Power: Once all tubes are securely installed, restore power to the fixture at the circuit breaker.
