Wiring Underwater Lights
Wiring underwater LED lights is easy when you only have one or two lights. But when wiring three or more lights, things start to get tricky. That’s where Shadow-Caster power distribution boxes come in handy.
Shadow-Caster makes three power distribution boxes. The SCM-PD, SCM-PD-Relay-4, and SCM-PD-Plus.
The SCM-PD and SCM-PD-Plus are a watertight, IP63 rated box with individually fused connectors and cable glands for up to six underwater lights. The SCM-PD-Relay-4 is a compact watertight, IP 63 rated box with individually fused connectors and cable glands for up to four underwater lights. They all keep your wiring dry, simple, neat, and secure.
Each light gets its own color-coded connectors that match the colors of the light’s wires. Wiring your light is fool-proof.
Each light gets its own fuse. Rest easy knowing your lights are well protected.
Cable glands tighten around the lights wire cable to help keep water out.
Shadow-Caster power distribution boxes should be mounted in a secure location in the console or under the deck near the back of the boat. This keeps the distance from the power supply to the box as short as posable.
How are They the Same?
- IP 63 Rated Box: Wires stay dry with fewer corrosion problems.
- Cable Glands: Stop water from seeping in around wires.
- Color Coded Connectors: Have peace of mind knowing your lights are wired the right way.
- Each Light Has Its Own Fuse: Have confidence knowing your light are protected.
- A ground wire connects the power distribution box to a negative bus bar to complete the circuit.
How are They Different?
-
- SCM-PD: Used mostly for single color underwater lights *. It is powered by a switch from the helm. The switch supplies power and controls the lights.
- SCM-PD-Plus: Used mostly for color changing underwater lights. Power is supplied by a nearby fuse or bus bar. The lights are controlled by a remote switch at the helm.The SCM-PD-Plus uses Shadow-Net technology to control lights.
- SCM-PD-Relay-4: Used mostly with color changing lights. The box can be powered in one of two ways.
1) Through a switch at the helm if the lights are controlled by the switch.
2) From a nearby fuse or bus bar if the lights are controlled through a zone controller.
The SCM-PD-Relay-4 uses Shadow-Net technology to control lights.

SCM-PD-Plus
Power Distribution Box for up to 6 Shadow-Caster Color Changing Underwater Lights.
The SCM-PD-Plus gives you all of the features of the SCM-PD, plus remote switching and Shadow-Net technology.
Remote Switching simplifies your wiring and saves you money on installation. The SCM-PD+ is powered by a nearby fuse block or bus bar instead of a switch at the helm. Often times, a shorter, thinner gauge wire can be used to power the box. Then, a low power switch is run from the helm to control the lights.
With Shadow-Net you are in complete control of your Shadow-Caster color-changing lights. Change the color of your lights to set a mood or dim them for a romantic evening. Get the party going by setting them to strobe, flash, fade, chase, or even dance to the music.
