5.2.1. Plug & Play (Type A - With Ballast)

1. Ensure the existing fluorescent fixture has a compatible ballast. Refer to the Ballast Compatibility List below.
2. Turn off power to the fixture at the circuit breaker.
3. Remove the old fluorescent tube.
4. Insert the JESLED T8 LED tube into the fixture's sockets. Ensure the pins are correctly aligned and twisted into place.
5. Restore power and test the light.

5.2.2. Ballast Bypass (Type B - Without Ballast)

This method requires modifying the fixture's wiring to bypass or remove the ballast. It is recommended that this procedure be performed by a licensed electrician or individuals with sufficient electrical knowledge.

1. Turn off power to the fixture at the circuit breaker.
2. Remove the old fluorescent tube and the fixture cover.
3. Locate and disconnect the ballast from the fixture's wiring. Remove the ballast completely.
4. Rewire the fixture according to the diagram for Ballast Bypass (Type B) shown above. Connect the incoming AC power directly to the lamp holders (tombstones).
5. For dual-ended powered bulbs, connect the live (hot) wire to the pins on one end of the tube and the neutral wire to the pins on the opposite end.
6. For single-ended powered bulbs, connect both live (hot) and neutral wires to the pins on one end of the tube.
7. Ensure all connections are secure and insulated. Replace the fixture cover.
8. Insert the JESLED T8 LED tube into the fixture's sockets.
9. Restore power and test the light.

8. Troubleshooting

• Bulb does not light up:
  1. Check if the power is on at the circuit breaker and the light switch.
  2. Ensure the bulb is securely seated in the lamp holders (tombstones) and the pins are correctly aligned.
  3. If using Plug & Play, verify the ballast is compatible and functioning correctly.
  4. If using Ballast Bypass, re-check all wiring connections according to the diagram. Ensure live and neutral wires are correctly connected to the appropriate ends of the bulb.
• Flickering or inconsistent light:
  1. If using Plug & Play, the ballast might be incompatible or failing. Consider bypassing the ballast or replacing it with a compatible one.
  2. Ensure stable power supply to the fixture.
