4. Installation Guide

Important Considerations:

• Always ensure the power supply to the fixture is turned OFF at the circuit breaker before beginning any installation.
• JESLED T8 Type A+B LED tubes are dual-end powered.
• These bulbs are compatible with both shunted and non-shunted tombstones.

Installation Methods:

Method 1: Plug & Play (with Ballast)

This method allows for direct replacement of existing fluorescent tubes without modifying the fixture's wiring, provided the existing ballast is compatible. Refer to the ballast compatibility list below.

1. Turn off power to the fixture at the circuit breaker.
2. Remove the existing fluorescent tubes from the fixture.
3. Insert the JESLED T8 LED tubes into the existing lampholders (tombstones).
4. Turn on power to the fixture.

Method 2: Ballast Bypass (without Ballast)

This method involves removing the existing ballast and directly wiring the LED tubes to the main power supply. This is recommended for maximum energy efficiency and to eliminate future ballast maintenance. This procedure should be performed by a licensed electrician.

1. Turn off power to the fixture at the circuit breaker.
2. Remove the existing fluorescent tubes and the ballast cover.
3. Disconnect and remove the existing ballast and starter (if present).
4. Wire the hot (L) wire to one end of the fixture's lampholders and the neutral (N) wire to the lampholders on the opposite end. Ensure proper polarity for dual-end powered tubes.
5. Replace the ballast cover.
6. Insert the JESLED T8 LED tubes into the lampholders.
7. Turn on power to the fixture.

Ballast Compatibility:

For Plug & Play installation, ensure your existing ballast is compatible. A detailed ballast compatibility list is often provided by the manufacturer. If your ballast is not on the list, or if you prefer to eliminate the ballast, use the Ballast Bypass method.

5. Operating Instructions

Once the JESLED T8 LED tubes are correctly installed, operating them is straightforward:

• Ensure the power supply to the fixture is turned ON at the circuit breaker.
• Use your existing wall switch or fixture pull chain to turn the lights ON or OFF.
• The LED tubes will provide instant, full brightness without any warm-up time or flickering.

6. Maintenance

JESLED T8 LED tubes require minimal maintenance due to their long lifespan and durable construction.

• Cleaning: Periodically wipe the tubes with a soft, dry cloth to remove dust. Do not use abrasive cleaners or solvents. Always turn off power before cleaning.
• Inspection: Occasionally inspect the tubes and fixture for any signs of damage or loose connections. If any issues are found, turn off power and consult a qualified electrician.
• Replacement: Due to the long lifespan, frequent replacement is not anticipated. If a tube fails, replace it with another compatible JESLED T8 LED tube.
