- Connect the daisy chain cable from the "OUT" port of the first light to the "IN" port of the next light.
- Repeat this process for all additional lights you wish to connect.
- Ensure all connections are secure before powering on the system.
5. Operating Instructions
5.1 Powering On/Off
Plug the power cord into a suitable electrical outlet. The light will illuminate. To turn off, unplug the power cord or use an external timer/controller if integrated.
5.2 Dimming Functionality
The Phlizon FD9600 features a dimming knob to adjust light intensity from 0-100% according to plant needs. This allows for precise control over light output during different growth stages.
5.3 Full Spectrum Lighting
The FD9600 provides a full spectrum of light essential for all stages of plant growth. It includes 3456 SMD LED beads, comprising 64 UV LEDs, 96 IR LEDs, 2240 3000K LEDs, 576 6500K LEDs, and 480 660nm red LEDs. This spectrum supports germination, vegetative growth, and flowering.

| Growth Stage | Recommended Hang Distance | Recommended Dimming | Light Cycle (Hours/Day) |
|---|---|---|---|
| Germination | 16 inches | 15-20% | 14 hours |
| Seedling | 16 inches | 20-25% | 18 hours |
| Vegetative | 16 inches | 45-50% | 18 hours |
| Bloom | 16 inches | 85-100% | 12 hours |
Note: These are general guidelines. Monitor your plants closely and adjust settings based on their specific needs and environmental conditions.
5.5 Coverage Area
The FD9600 provides excellent coverage for various grow spaces. One unit is ideal for a 4x4ft, 5x5ft, 6x6ft, or 7x7ft area, with up to 7.2x7.6ft coverage in the vegetative stage and 7x7ft for the flowering stage.

6. Maintenance
- Cleaning: Regularly clean the LED bars and heat sinks to ensure optimal heat dissipation and light output. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the power cord, hanging cables, and all connections for any signs of wear, damage, or loose fittings. Address any issues promptly.
- Ventilation: Ensure adequate airflow around the light fixture to prevent overheating. The light features a real heat sink made of thick aluminum for efficient cooling.
7. Troubleshooting
If you encounter issues with your Phlizon FD9600 LED Grow Light, refer to the following common troubleshooting steps:
- Light Not Turning On:
- Check if the power cord is securely plugged into both the light and the electrical outlet.
- Verify that the electrical outlet is functional by plugging in another device.
- Ensure the dimming knob is not set to "OFF" or minimum brightness.
- Uneven Light Output:
- Inspect all connections between LED bars and drivers to ensure they are secure.
- Check for any physical damage to individual LED bars.
- Dimming Function Not Working:
- Ensure the dimming knob is properly engaged and rotating freely.
- If using daisy chain, ensure the control is from the designated master unit.
- Overheating:
- Ensure the light is installed in a well-ventilated area.
- Check for any obstructions blocking the heat sinks.
