SCM-LC-MFD-KIT gives you complete control of your RGB lighting through your MFD. The kit connects the LED light controller to your MFD through a communication bridge. It features six zones of lights, millions of light colors, unlimited lighting scenes, various lighting modes, and music sync. It works with Shadow-NET-enabled lights and standard RGB/RGBW deck lights.
The Shadow-Caster Light Commander is an NMEA LED light controller for boats with an NMEA 2000 network. The controller connects to the boat’s NMEA 2000 network through its backbone cable. Once connected, the network recognizes the controller, and it can be operated through a compatible multifunction display. Unfortunately, not all MFD models support the new NMEA 2000 lighting standards. Some need an Ethernet network connection to communicate with light controllers.
For this reason, Shadow-Caster has two models in the Light Commander series. The SCM-LC-N2K is for use with MFDs that support the NMEA 2000 lighting standard. The SCM-LC-N2K-PLUS-V2 is for MFDs that can be connected through an Ethernet or Network cable. You can see a list of compatible multifunction displays here.

How Zones, Modes, and Scenes Work
What Are the Benefits of Marine Speakers with RGB Lighting and Remote Control?
Integrating marine RGB deck lighting with a remote-controlled lighting system (such as the Shadow-Caster Light Commander) provides three major advantages:
- System-Wide Visual Harmony: Synchronize the color and brightness of your overhead, underwater, and gunwale strip lights eliminates mismatched light shades across your boat.
- DSP Music Synchronization: Using the built-in 3.5mm audio input or internal Digital Signal Processor (DSP) microphone in Shadow-Caster controllers, your RGB underwater and deck lights pulse, fade, and change color in real-time to the rhythm of your audio.
- Effortless Helm & Smartphone Control: Rather than using cheap, line-of-sight infrared remotes that fail in marine environments, remote-controlled marine RGB systems let you adjust lighting scenes, dimming, and color wheels directly from your helm MFD touchscreen or via Wi-Fi/Bluetooth on your smartphone.
