For your safety, use a non-contact voltage tester and ensure that your fixture is properly disconnected.
Step 2: Remove the Fluorescent Tubes
Now gently twist the connected sockets and disconnect the fluorescent tubes from the fixtures. These types of tubes typically contain mercury, so you need to handle them very gently to avoid breakage. The best is that you wear gloves and safety glasses during removal.
In case you are disconnecting multiple fixtures, safely store the disconnected tubes in a place or manage to recycle them according to local regulations.
Step 3: Disconnect the Ballast (If Applicable)
Now, depending on the model or types you have chosen, you may need to remove or bypass the fluorescent ballast. If there is a ballast-bypass tube at hand, make sure the ballast is properly disconnected.
Also, remove it from the place as the LED tube runs directly on the line voltage. If it is plug-and-play LED tubes, keep the ballast just in its place. But check and ensure that the type of LEDs is perfectly compatible with the ballast to avoid flickering or damage.
Step 4: Install Non-Shunted Tombstone Sockets (If Necessary)
If you are rewiring the fixture for ballast bypass, replace the existing shunted tombstone sockets with non-shunted tombstones. Non-shunted sockets have separate electrical connections for each pin, and this is important for single-ended LED tubes.
But with the shunted sockets, you will find both pins internally connected, so that the power flows through both at once. It is best for the double-ended LED tubes where there is not much to change the sockets.
Step 5: Wire the Fixture
Rewire the fixture according to the LED tube type. Follow the manufacturer’s instructions in this instance. If it is ballast bypass tubes, connect the line and neutral wires directly to the appropriate tombstone sockets.
Must ensure a secure connection with wire nuts, electrical tape, and proper insulation. Before you complete the installation, check the LED tube’s datasheet and ensure it follows electrical safety codes. It is important for safety.
Step 6: Install the LED Tubes
Now is the time to insert the LED tubes into the fixture sockets. After you have done it, check and ensure a secure fit. Confirm all the tubes are compatible with the fixture size and the recommended base types.
Step 7: Restore Power and Test
After installing the LED tubes, just connect the power back on at the circuit breaker. Make sure to carefully connect with the safety of yourself. When done, just switch back on and check your new LED lights to see whether they light perfectly or not. It should not flicker or buzz after you have switched it on.
If you face any issues, double-check the wiring or whether you are running into any compatibility issues. In this case, it is better to contact a professional technician for further assistance.
