3. Setup & Installation
The LyLmLe LED Pool Light is designed for easy installation across various pool types. It utilizes a magnetic attachment system or a metal base for secure placement.
General Installation Steps:
- Prepare the Pool Light: Ensure the light unit is clean and free of debris.
- Power Connection: Connect the light to the provided 12V transformer. Plug the transformer into an outdoor outlet. The transformer steps down the voltage to a safe 12V for underwater operation.
- Placement: Follow the specific instructions below based on your pool type.
Installation for Steel Above-Ground Pools:
For steel above-ground pools, the light can be directly adsorbed onto the metal steel pool wall using its built-in strong magnets.
- Simply place the light unit on the inner side of the pool wall. The strong magnets will secure it in place.
- Ensure the power cord is routed safely over the edge of the pool and connected to the transformer.

Installation for Soft-Sided Frame Pools:
For soft-sided frame pools, separate the round metal plate from the lamp. Place the lamp on the inner side of the pool wall and the round metal plate on the outer side, aligning them so the magnets hold the light in place.

Installation for Inground Pools & Non-Steel Pools:
For inground pools or non-steel above-ground pools, use the included round metal base and waterproof glue to secure the light.
- Clean the Surface: Wipe off any dirt or algae from the desired installation area on the pool surface. The glue can be applied directly underwater.
- Apply Glue: Apply an appropriate amount of the provided waterproof glue to the middle circle of the round metal base.
- Attach Base: Press the metal base firmly onto the cleaned pool surface for approximately 10 seconds.
- Curing Time: Wait for 1 hour until the glue is fully dry and cured.
- Attach Light: Align the light unit with the two protruding spots on the metal base and fix it to prevent slipping.
