🔬 How It Works
The PU2MLPL+B utilises advanced RGBW LED technology combined with Wi-Fi connectivity to deliver stunning underwater lighting effects:
1️⃣ RGBW LED Technology The RGBW unit offers the flexibility to allow a choice of colours and shades, create programmable lighting sequences, and to be dimmable. Four LED colours (Red, Green, Blue, White) combine to create virtually unlimited colour combinations with output reaching 1,750-2,000 lumens on white and 450-500 lumens on RGB.
2️⃣ Wi-Fi 104 Control System RGBW lights are operated via the control unit and/or App provided with the Wi-Fi 104 unit. The free downloadable app (iOS and Android) provides full control over colour selection, brightness levels, and pre-programmed sequences.
3️⃣ R4-CC Driver Receiving Controller Each RGBW light requires its own R4-CC driver receiving controller (PU2MLRC), which interprets signals from the Wi-Fi controller and adjusts the LED output accordingly. Multiple lights synchronise perfectly for coordinated effects.
4️⃣ 24V SELV Power Supply The dedicated power supply (PU2MLPS 24V 320W) provides safe, low-voltage power. One power supply can operate up to 26 lights, making multi-light installations cost-effective.

Installation Procedure (per Official Manual)
- The liner fitting and the liner should be installed as normal
- The light body is threaded and shaped in order to be a perfect fit into and over the liner inlet clamp plate
- The pipework connected to the inlet fitting/s should be extended/converted to conduit which then runs above the water level to create a run for the cable to the central control/power point
- When the light cable is fed through the receiving pipe/conduit, sufficient cable should remain free within the pipe in order to be able to remove the light unit to the pool surround
- Run the cable through the pipe/conduit back to the desired control/power point
- Coil the free cable into the pipe and insert the light body – position the light body within the inlet fitting and screw the light into place
- When fully installed the light body will cover the inlet clamp plate exactly
Installation Notes
⚠️ WARNING: This equipment must be installed by qualified persons only
⚠️ NOTICE: The inlet fitting should be for use by the light only – it should not be connected to the pool circulation system
⚠️ Install between 400-700mm below water level for optimal lighting coverage
