3. Setup and Installation
Follow these steps for proper installation of your LyLmLe LED pool light. Professional installation is highly recommended.
Wiring Diagram:

Figure 5: Wiring Diagram. Connect AC 220V input to a compatible transformer, then 12V AC output to the sync controller, and finally to the pool lights. Ensure total cable length (L1+L2) is less than 50m and copper core diameter is at least 1.5mm².
Installation Steps:
- Prepare the Installation Area: Ensure the pool wall is clean and free of debris. The light should be installed at the recommended depth (min 450mm from water level).
- Mount the Cross Brace: Secure the standard cross brace to the pool wall using appropriate screws.
- Connect Wiring: Route the electrical cable through the designated opening in the cross brace. Connect the light's cable to the 12V AC output from your transformer/sync controller, ensuring waterproof connections.
- Attach the Light: Align the light with the mounted cross brace and secure it firmly by tightening the screws.

4. Operating Instructions
The LyLmLe LED pool light offers 14 distinct color modes for a customizable lighting experience. While the lamp itself does not include a controller, it is designed to work with an external synchronous controller (e.g., models RF433C and R-RF433R, available separately from LyLmLe).
Color Modes and Control:

Figure 7: 14 RGB Program Modes and Remote Control.
- Static Modes (7): Red, Green, Blue, Yellow, Pink, Cyan, White. Brightness is adjustable for these modes.
- Dynamic Modes (7): Full Color Smooth, 6 Color Fade out and Fade in, 6 Color (RGBYPC) Jumping, 3 Color (RGB) Jumping, Red Green Color Smooth, Red Blue Color Smooth, Green Blue Color Smooth. Speed is adjustable for these modes.
- Synchronization: If you have multiple LyLmLe synchronous pool lights connected to the same controller, they will synchronize their color changes.
- Control: Use the external synchronous controller (remote or wall-mounted unit) to switch between modes, adjust brightness, and change speed. Refer to the controller's specific instructions for detailed operation.
5. Maintenance
The LyLmLe LED pool light is designed for minimal maintenance due to its robust construction.
Cleaning:
- Periodically clean the surface of the light to remove any algae, mineral deposits, or debris that may accumulate and affect light output.
- Use a soft cloth or sponge and mild, non-abrasive cleaning solutions specifically designed for pool equipment. Avoid harsh chemicals that could damage the light's resin or plastic components.
- For information on recycling your bulbs, please refer to local recycling guidelines.
Durability and Waterproofing:
The light's resin-filled interior provides superior protection against water intrusion.

6. Troubleshooting
If you encounter issues with your LyLmLe LED pool light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply; Incorrect transformer; Loose wiring; Faulty light. | Check power source and circuit breaker. Verify transformer type (must be double-wound safety isolating). Inspect all wiring connections for tightness. If issues persist, contact support. |
| Colors are incorrect or not changing. | Controller issue; Synchronization issue (multiple lights); Power cycle needed. | Ensure the external controller is functioning correctly and within range. For multiple lights, ensure they are properly synchronized. Try turning the power off to the light for 10 seconds, then back on. |
| Remote control not working. | Battery low/dead; Remote out of range; Interference. | Replace remote batteries. Ensure remote is within effective range of the sync controller. Minimize potential signal interference. |
| Light flickers or dims unexpectedly. | Unstable power supply; Voltage drop; Overheating. | Verify stable 12V AC power. Check cable length and gauge (L1+L2 < 50m, copper core ≥ 1.5mm²). Ensure adequate water circulation around the light to prevent overheating. |
