🔬 How It Works

The PU2MLP utilises advanced RGBW LED technology combined with Wi-Fi connectivity to deliver stunning underwater lighting effects:

1️⃣ RGBW LED Technology Four LED colours (Red, Green, Blue, White) combine to create virtually unlimited colour combinations. The high-quality LEDs deliver exceptional brightness with white output reaching up to 2,000 lumens.

2️⃣ Wi-Fi 104 Control System The Wi-Fi controller connects to your smartphone via a free downloadable app (iOS and Android). This provides full control over colour selection, brightness levels, and pre-programmed sequences – all from the palm of your hand.

3️⃣ Receiving Controller Each RGBW light requires its own receiving controller (PU2MLRC), which interprets signals from the Wi-Fi controller and adjusts the LED output accordingly. Multiple lights synchronise perfectly for coordinated displays.

4️⃣ 24V SELV Power Supply The dedicated power supply (PU2MLPS) provides safe, low-voltage power. One power supply can operate up to 26 lights, making multi-light installations cost-effective.

⚡ Electrical Requirements

Specification	Value
Input Voltage	24VDC
Drive Current	350mA
Power Supply Required	PU2MLPS (24V 320W) – sold separately
