5. Setup and Installation
Follow these steps for proper installation of your JOYINLED 3W COB LED Downlights. Ensure power is disconnected before beginning.
- Prepare the Installation Area:
Identify the desired location for each downlight. Ensure there is sufficient space above the ceiling or cabinet for the fixture and driver. Mark the center point for each light.
- Cut the Mounting Hole:
Using a hole saw, carefully cut a circular hole with a diameter of 40-45mm (1.57-1.77 inches) at each marked location. Ensure the hole is clean and smooth.
- Wiring the Driver:
Connect the input wires of the LED driver to your main AC power supply (85-265V). The driver has two input wires, typically brown (Live) and blue (Neutral). Connect them securely to the corresponding wires from your electrical supply. Ensure power is OFF during this step.
- Connect Downlight to Driver:
Connect the output cable from the LED driver to the input cable of the downlight. These connections are typically plug-and-play for ease of installation. Ensure the connection is firm.
- Insert the Downlight:
Push the spring clips on the sides of the downlight upwards. Carefully insert the downlight into the prepared hole. The spring clips will automatically secure the fixture in place once it passes through the hole.
- Adjust Direction (Optional):
Once installed, the inner eyeball of the downlight can be gently tilted to adjust the light beam direction as needed.
- Restore Power:
After all lights are securely installed and wired, restore power at the circuit breaker. Test the lights to ensure proper operation.

6. Operation
The JOYINLED 3W COB LED Downlights operate simply once installed.
- Turning On/Off: Control the lights using the standard wall switch connected to the circuit.
- Adjusting Light Direction: Gently pivot the inner light module (eyeball) within the fixture to direct the light beam to your desired area.
- Non-Dimmable: These lights are designed for on/off operation only and are not compatible with dimmer switches.

- Cleaning: Ensure power is off before cleaning. Use a soft, dry cloth to wipe the fixture. Do not use abrasive cleaners, solvents, or liquids directly on the light.
- No User-Serviceable Parts: The LED module and driver are sealed units. Do not attempt to open or repair them.
- Regular Inspection: Periodically check for any loose connections or visible damage. If any issues are found, disconnect power and consult a qualified electrician.
8. Troubleshooting
If you encounter issues with your JOYINLED Downlights, refer to the following table for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply. Loose wiring connection. Faulty driver or LED. | Check circuit breaker/fuse. Ensure wall switch is on. Verify all wiring connections are secure (with power off). If other lights on the same circuit work, the individual driver or LED may be faulty. Contact support. |
| Light flickers. | Loose wiring. Incompatible dimmer switch (if used). Driver malfunction. | Check wiring connections (with power off). This model is not dimmable. Remove any dimmer switch and replace with a standard on/off switch. Contact support if the issue persists. |
