Product Research

Features

Overview: The Shadow-Caster SCM-4 series underwater light bar lets you add intense, colored LED lighting to your marine craft. Its low-profile design allows it to be mounted in a variety of locations. With an IP68 waterproof rating, the SCM-4 is fully submersible and can be mounted below the waterline.

Construction: The SCM-4 features a heavy-duty housing that's made with passivated 316 stainless steel, providing durable corrosion resistance. The four built-in LEDs are protected by a tough polycarbonate outer lens, and the entire internal space is filled with a proprietary clear-gel that eliminates condensation and water intrusion while under stress.

LEDs: Four built-in color LEDs provide up to 1600 lumens with a wide 120˚ beam angle. Thermal throttling technology enables safe LED operation, even when out of the water. Transient surge and reverse polarity protection help prolong LED life.

Power: The SCM-4 can operate on 10-30 volt systems, and consumes 1.4A (17 watts) of current @12V. A built-in 20' wiring harness gets run through the hull of your marine craft and attached to a power and ground source inside. The wire harness is encased in a heavy-duty outer jacket for added water- and damage-protection. The 3-wire harness includes:

  • Red: +10-30V Power connection
  • Black: Chassis ground
  • Blue: This Pulse-Width Control (PWM) wire is used to control the dimming and strobing functions integrated into the light, via an optional Shadow-Caster Marine LED Lighting Controller (sold separately).

    Notes:

    • Each installed SCM-4 underwater light should be wired to a 3A fuse/breaker circuit (not included) inside the craft. This allows it to handle the 1.4A nominal draw along with the current in-rush when first powered on.
    • A 0.50" hole will need to be drilled through your marine craft's hull for running the attached cable.

Optional Colors: The Shadow-Caster SCM-4 series of marine underwater lighting is available in the following LED colors: Cool Red, Bimini blue, Ultra Blue, Great White, and Aqua Green. All can be found here.
