Shadow-Caster SCR-24 Round Underwater Marine Light - 24 LEDs - Bronze
Description
The Shadow-Caster SCR-24 is a professional-grade 24-LED round underwater marine light engineered to transform your vessel's presence on the water. Delivering up to 7,500 lumens and 90 watts of intense output from a compact 4-inch bronze housing, this light is built for under-waterline surface mounting on any boat. Its proprietary clear-gel-filled design eliminates condensation and water intrusion even under stress, while a tough tempered glass lens and bronze housing stand up to acetone, solvents, and the harshest marine environments.
Available in single-color, dual-color, and full-color-changing configurations, the SCR-24 offers flexible control options ranging from simple power toggle to full multifunction display integration via Shadow-NET technology. Designed and manufactured in Clearwater, Florida, USA, this is a light built to perform night after night on the open water.

FAQ
What is the difference between the Full Color Changing model and the single-color models?
The Full Color Changing (CC) model includes 12 built-in colors and supports advanced features like unlimited color control, fading, strobe, dimming, and music sync when paired with the Shadow-NET control module. Single-color models (Bimini Blue, Aqua Green, Great White) output one fixed color and are simpler to install and operate - ideal if you know exactly what look you want. The Bimini Blue/Great White is a dual-color option that lets you toggle or fade between two colors.
What control options are available for the SCR-24?
The SCR-24 supports three control methods: Power Toggle (toggle your power switch to cycle through colors and brightness levels), Push Button (connect any push button controller for more precise control), and Shadow-NET (full multifunction display integration for unlimited color, dimming, zone control, music sync, and more). Shadow-NET requires the optional SCM-MFD-LC control module.
Is the SCR-24 compatible with my boat's electrical system?
Yes - the SCR-24 accepts 10-30 volts DC input, making it compatible with both 12V and 24V marine electrical systems. It draws 7.8 amps at 12 volts (90 watts), so make sure your circuit is appropriately fused for the number of lights you plan to install.
Can I run the SCR-24 out of the water?
Yes. Shadow-Caster's thermal throttling technology allows the SCR-24 to operate safely even when it is not submerged, protecting the LEDs from overheating. This is particularly useful during testing and installation on the hard.
What MFD brands are compatible with Shadow-NET control?
Shadow-NET integrates with all major multifunction display brands including Garmin, Raymarine, Furuno, Simrad, Lowrance, and B&G. You will need the Shadow-NET SCM-MFD-LC control module (sold separately) to enable MFD control.
How is the SCR-24 mounted?
The SCR-24 is designed for under-waterline surface mounting on the hull of the vessel. Full installation instructions are available as a downloadable PDF on this page. No special through-hull fitting is required for the mounting style.
