6.2. Adapter Replacement

The separable adapter design allows for easy replacement if damaged, preventing the need to replace the entire light fixture.

7. Troubleshooting

• Light not turning on: Check all power connections. Ensure the adapter is securely plugged into both the light and the wall outlet.
• Moisture inside the light: While the lamp beads are waterproof, prolonged exposure to high humidity or direct water spray on the control unit can cause issues. Ensure the light is properly positioned to minimize condensation or splashes reaching the control unit. If moisture is observed, immediately unplug the unit and allow it to dry completely in a well-ventilated area before reconnecting.
• Settings not saving: Ensure you press the Mode Setting button to confirm and save changes after adjusting time or mode settings. The power-off memory function retains settings, but local time may default to 12 noon after a power outage.
• Inconsistent light output: Verify that the light is not in Gradient Mode if you expect static colors. Check DIY Mode settings for any unintended brightness changes.
