6. Maintenance

• Cleaning: Use a soft, dry towel to wipe the light fixture. Do not use abrasive cleaners or solvents.
• Water Resistance: The light has an IP68 rating, meaning it is protected against dust and can withstand immersion in water up to 1.5 meters for 30 minutes. However, it is recommended to keep the controller and power adapter dry.
• Heat Dissipation: The aluminum housing is designed for effective heat transfer. Ensure the heat sink fins are not obstructed to maintain optimal performance.

7. Troubleshooting

• Light does not turn on: Check if the power adapter is securely connected to the outlet and the controller. Ensure the light is properly connected to the controller.
• Timer settings are lost after power outage: The light has a memory function for programmed settings. However, if the current time is not displayed on the clock after a power interruption, re-enter the 24/7 mode and select the nearest local time. The light will then run according to the time you set.
• Light is not dimming or changing colors: Ensure you are in the correct operating mode (e.g., Manual Mode for direct control, or DIY Mode for custom settings). Refer to section 5.2 for mode-specific instructions.
• Algae growth: Excessive light intensity or duration can contribute to algae. Consider reducing the brightness or shortening the light cycle in DIY mode.
