Wiring high bay LED lights with a dimmer involves a straightforward process, but it's essential to ensure compatibility between the dimmer switch and the LED lights to avoid any issues such as flickering or improper dimming. Here’s a step-by-step guide:

Materials Needed:

1. High bay LED lights
 

2. Dimmer switch compatible with LED lights (ensure it's rated for the total wattage of your LEDs)
 

3. Wire nuts
 

4. Electrical tape
 

5. Wire strippers
 

6. Screwdrivers
 

7. Multimeter (optional, for testing)

Steps:

1. Turn off the Power: Ensure the power to the circuit where you will be working is turned off at the circuit breaker.

2. Verify Power is Off: Use a voltage tester or a multimeter to confirm that no electricity is flowing through the wires where you'll be working.

3. Prepare the Dimmer Switch:

• Read the manufacturer's instructions for the dimmer switch. Typically, you'll need to connect the incoming power wires (usually black) to the dimmer switch’s wires (often black).
• If the dimmer switch requires a ground connection, connect the green or bare copper wire from the switch to the grounding wire in the junction box.

4. Wire Connections:

• Incoming Power: Identify the hot (usually black) and neutral (usually white) wires coming from your electrical panel.
• LED Light Fixture: Identify the wires from your high bay LED lights. Typically, these will include a hot wire (black), a neutral wire (white), and possibly a ground wire (green or bare copper).
• Connect the hot wire (black) from the incoming power supply to the hot wire (black) from the LED light fixture using a wire nut.
• Connect the neutral wire (white) from the incoming power supply to the neutral wire (white) from the LED light fixture using a wire nut.
• If there is a ground wire from the LED light fixture, connect it to the ground wire (if available) in the junction box using a wire nut.

5. Dimmer Switch to LED Lights:

• The output wires from the dimmer switch (usually black and red) need to be connected to the corresponding wires of the LED light fixture.
• Connect the output hot wire (often black or red) from the dimmer switch to the hot wire (black) of the LED light fixture using a wire nut.
• Connect the output neutral wire (often white) from the dimmer switch to the neutral wire (white) of the LED light fixture using a wire nut.

6. Final Checks:

• Double-check all connections to ensure they are secure and properly insulated with wire nuts and electrical tape if necessary.
• Ensure all ground wires (if applicable) are properly connected.

7. Mount the Dimmer Switch:

• Carefully fold the wires back into the junction box, ensuring not to pinch or crimp any wires.
• Attach the dimmer switch to the junction box using the provided screws.

8. Turn on Power and Test:

• After verifying all connections are secure, turn the power back on at the circuit breaker.
• Test the dimmer switch to ensure it dims the LED lights properly without any flickering or issues.

9. Adjust Settings:

• Some dimmer switches may have adjustment settings for minimum and maximum dimming levels. Refer to the dimmer switch's manual for any adjustments needed.

By following these steps and ensuring all connections are secure and compatible with your LED lights and dimmer switch, you should be able to wire high bay LED lights with a dimmer effectively and safely. Always prioritize safety and consult a qualified electrician if you are unsure about any step of the process.
