How to Install a T8 LED Tube Replacement Bulb for a Traditional Fluorescent Tube Light

WARNING: When dealing with high voltage, precautions must be taken to ensure safety and reliability.  Always test the circuit to ensure power is completely disconnected.  Consult a licensed electrician if you are not comfortable with these procedures or have questions about local electrical codes.

  1. Turn off circuit going to fixture. Unplug or turn off breaker.
  2. Locate ballast, cut wires from the one end. We suggest the end that is closest to where the AC power will be entering the fixture.
  3. Each socket on the fixture has two same color wires: cut all 4 of the wires. Give yourself enough wire to be able to connect it to the entering AC power wire – one wire from each socket will go to “Line” and other one to “Neutral”.
  4. Use wire nuts to cover exposed end of any wires and connect line and neutral wires. Ground can be connected to fixture screw or capped off.
  5. When wiring is completed, one side will be the AC input side and the other side will have no electric current traveling to it. You have the option of taking out the ballast completely or leaving it inside fixture. In the method shown in this video, there will be no current going back to the ballast.
  6. Close fixture and find your AC Input side to LED tube lamp.
  7. Power must be applied to the end cap labeled “AC INPUT”. Applying power to wrong end will cause a direct short of the AC power when turned on.
  8. When the AC input side is attached to the AC power side on fixture, you are ready to go. Turn power circuit back on from breaker.
