5. Installation Instructions
Follow these steps for safe and proper installation:
- Preparation: Ensure the power supply is turned off at the circuit breaker before beginning installation. If replacing an old fixture, carefully remove it.
- Install Mounting Clips: Screw the provided mounting clips onto the desired surface (wall or ceiling). Ensure they are spaced appropriately for the 4FT fixture.
- Attach LED Tube Light: Gently snap the LED tube light into the installed mounting clips. Ensure it is securely seated.
- Connect to Power Source:
- Plug-and-Play: For simple operation, connect the power cord with the ON/OFF switch to the light fixture, then plug it into a standard AC outlet.
- Hardwired Connection: For a permanent installation, use the pigtail power cable. Connect the black or brown wire to the live wire, the white or grey wire to the neutral wire, and the yellow or green wire to the ground wire. Ensure all connections are secure and insulated.
- Multiple Lights Installation (Linking):
- Seamless Connection: For a continuous run, connect the output end of one fixture directly to the input end of the next using the seamless connector.
- Connection Cords: Use the short jumper connector cords to link fixtures that are spaced apart.
- Linking Limit: For 4FT lights, do not link more than 8 lights together in a single run to prevent burnout or melting due to cumulative wattage.
- End Cap: If the rear end of the last light in a series is not connected to another lamp, always plug it with a small cover to prevent electric shock.
- Restore Power: Once all connections are secure and safety measures are in place, restore power at the circuit breaker.

8. Troubleshooting
If you encounter issues with your SHOPLED 4FT LED Shop Light, consider the following:
- Light Does Not Turn On:
- Check if the power cord is securely plugged into the outlet and the fixture.
- Verify that the ON/OFF switch (if applicable) is in the 'ON' position.
- Ensure the circuit breaker supplying power to the fixture is not tripped.
- Confirm that the power source voltage is correct.
- Flickering Light:
- Check all connections for looseness.
- Ensure the number of linked lights does not exceed the recommended limit (8 for 4FT lights). Overloading can cause instability.
- Partial Light Failure in a Linked Series:
- Inspect the connections between the affected lights.
- Ensure the end cap is properly installed on the last fixture in the series if no further lights are connected.
