5. Setup & Installation
These LED tube lights support two primary installation methods: Plug & Play (Ballast Compatible) and Ballast Bypass (Direct Wire). Always disconnect power before beginning any installation.
5.1. Plug & Play Installation (Type A)
This method utilizes your existing electronic ballast. No rewiring of the fixture is required, provided your ballast is compatible.
- Disconnect Power: Turn off power to the fixture at the circuit breaker.
- Remove Old Tubes: Carefully remove existing fluorescent tubes from the fixture.
- Check Ballast Compatibility: Refer to the "Compatible Ballast List" (Section 5.3) to ensure your electronic ballast is compatible. If your ballast is not listed or is a magnetic ballast, you must use the Ballast Bypass method.
- Install LED Tubes: Insert the GoToLed Light T8 LED tubes into the existing lamp holders (tombstones). Ensure they are securely seated.
- Restore Power: Turn power back on at the circuit breaker.
- Test: Verify the lights illuminate correctly.

5.2. Ballast Bypass Installation (Type B)
This method involves bypassing or removing the existing ballast and directly wiring the LED tubes to the main power supply. This can be done with either single-end or double-end powered connections.
- Disconnect Power: CRITICAL: Turn off power to the fixture at the circuit breaker. Verify power is off using a voltage tester.
- Remove Old Tubes: Carefully remove existing fluorescent tubes.
- Remove/Bypass Ballast:
- Locate the ballast within the fixture.
- Cut all wires leading to and from the ballast.
- Remove the ballast from the fixture.
- Wiring for Single-End Powered Connection:
- Ensure you are using non-shunted lamp holders/tombstones for single-end wiring.
- Connect the Live (L) wire from the main power supply to one pin of the lamp holder on one end of the fixture.
- Connect the Neutral (N) wire from the main power supply to the other pin of the same lamp holder.
- The lamp holders on the opposite end of the fixture will not be wired.
- Wiring for Double-End Powered Connection:
- This method can work with existing shunted lamp holders/tombstones.
- Connect the Live (L) wire from the main power supply to the lamp holders on one end of the fixture.
- Connect the Neutral (N) wire from the main power supply to the lamp holders on the opposite end of the fixture.
- Ensure proper polarity (Live to Live, Neutral to Neutral) if applicable to your fixture.
- Install LED Tubes: Insert the GoToLed Light T8 LED tubes into the wired lamp holders.
- Restore Power: Turn power back on at the circuit breaker.
- Test: Verify the lights illuminate correctly.

5.3. Compatible Ballast List
For Plug & Play installation, verify your existing electronic ballast is listed below. If your ballast is not on this list, or if it is a magnetic ballast, you must perform a Ballast Bypass installation.

6. Operating Instructions
Your GoToLed Light T8 LED Tube Light features adjustable color temperature and wattage settings.
6.1. Adjusting Color Temperature (CCT)
Each tube light has an integrated switch to select the desired color temperature.
- Locate the small switch on the end of the LED tube.
- Slide the switch to select one of the four available color temperatures: 3000K, 4000K, 5000K, or 6500K.
- The change will be immediate once the light is powered on.

6.2. Adjusting Wattage/Brightness
Each tube light also features a switch to select the desired wattage, which directly affects the brightness.
- Locate the wattage selection switch on the end of the LED tube.
- Slide the switch to choose between 12W, 15W, 18W, or 22W.
- The brightness will adjust accordingly (12W for 1560 lumens, up to 22W for 2860 lumens).
7. Maintenance
GoToLed Light T8 LED Tube Lights are designed for low maintenance and a long operational life.
- Cleaning: Ensure power is off before cleaning. Use a soft, dry, or slightly damp cloth to wipe the tube. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the tubes and fixture for any signs of damage or loose connections.
- Replacement: With a 50,000-hour lifespan, regular replacement is not anticipated under normal usage.
8. Troubleshooting
If you encounter issues with your LED tube lights, refer to the following common troubleshooting steps.
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power to the fixture. Incorrect installation method. Incompatible ballast (for Plug & Play). Loose connection. | Check circuit breaker and wall switch. Verify installation method (Plug & Play vs. Ballast Bypass) is correct for your setup. If Plug & Play, check ballast compatibility or consider Ballast Bypass. Ensure tubes are securely seated in lamp holders. |
| Light flickers. | Incompatible ballast (for Plug & Play). Loose connection. | If Plug & Play, ensure ballast is compatible. Ballast Bypass typically eliminates flickering. Re-seat the tube firmly. |
| Incorrect color temperature or brightness. | CCT/Wattage switch set incorrectly. | Adjust the CCT and wattage switches on the tube to your desired setting. |
| Buzzing sound. | Old magnetic ballast (for Plug & Play). | If using Plug & Play with an old ballast, consider performing a Ballast Bypass installation to eliminate ballast noise. |
If problems persist after attempting these solutions, contact customer support.
