This method bypasses the existing ballast, connecting the LED tubes directly to the main power supply. This eliminates ballast maintenance and further improves energy efficiency. This installation should be performed by a licensed electrician.
- Strom ausschalten: Disconnect power to the fixture at the circuit breaker.
- Remove old fluorescent tubes and ballast: Carefully remove the existing fluorescent tubes. Then, disconnect and remove the ballast from the fixture.
- Rewire the fixture: Connect the live (L) and neutral (N) wires directly to the lamp holders (tombstones) according to the diagram provided. These tubes support both single-ended and double-ended wiring configurations.
- Insert LED tubes: Align the pins of the JESLED T8 LED tube with the rewired sockets. Push firmly and twist to secure.
- Stromversorgung wiederherstellen: Turn on power at the circuit breaker. The LED tubes should light up instantly.
