• Splash-proof: The light is IPX4 splash-proof, meaning it is resistant to water splashes from any direction. However, it is not fully submersible. Do not immerse the light in water.
• Heat Dissipation: The aluminum alloy shell is designed for efficient heat dissipation. Ensure adequate airflow around the light to prevent overheating.

7. Troubleshooting

• Light not turning on: Check if the power adapter is securely connected to both the light and the electrical outlet. Ensure the outlet is functional.
• Light flashing or erratic behavior: This could indicate a power supply issue or potential overheating. Ensure the light is not covered and has proper ventilation. Try unplugging and replugging the power adapter. If the issue persists, contact customer support.
• Timer not working as expected: Ensure you have correctly set both the desired duration and brightness for Day-L and Moon-L modes. Remember that the timer countdown resets to 0 upon power disconnect or timer duration adjustments.
• Light feels hot: While the aluminum housing is designed for heat dissipation, prolonged use can make it warm. If the light feels excessively hot to the touch or exhibits erratic behavior, unplug it immediately and contact customer support.
