4. Setup and Installation
These Barrina LED tube lights are designed for easy installation, but require bypassing or removing the existing fluorescent ballast. Always ensure power is OFF before starting.
4.1 Ballast Bypass Wiring (Dual-Ended Power Supply)
This installation method involves removing the existing ballast and directly wiring the LED tubes to the main power supply. This is a Type B installation (Hot at one end, Neutral at the other).
- Turn Off Power: Locate the circuit breaker controlling the light fixture and turn off the power. Verify with a voltage tester that the power is off.
- Access Wiring: Open the light fixture to access the ballast and wiring.
- Remove Ballast: Carefully cut off all wires connected to the ballast. Remove the ballast from the fixture.
- Prepare Wires: Strip the ends of the wires that were connected to the ballast and tombstone sockets.
- Connect Live Wire: Connect the live (hot) wire from the power supply to the wires leading to one end of the LED tube sockets. Secure with wire nuts and electrical tape.
- Connect Neutral Wire: Connect the neutral wire from the power supply to the wires leading to the other end of the LED tube sockets. Secure with wire nuts and electrical tape.
- Ground Wire: Ensure the ground wire (typically green or bare copper) is securely connected to the fixture's metal housing.
- Secure Wiring: Neatly tuck all wiring back into the fixture and close the cover.
- Insert LED Tubes: Carefully insert the Barrina LED tubes into the fixture sockets.
- Apply Warning Label: Affix the provided warning sticker to the fixture, indicating that it has been modified for LED tubes and no longer uses a ballast or fluorescent lamps.
- Restore Power: Turn the power back on at the circuit breaker.
