Shadow-Caster SCM-PD4CH power distribution and protection for up to four underwater boat lights. Underwater boat lights draw relatively high amounts of current. Two or more can draw more current then a switch can handle.

The SCM-PD4CH draws power from a local source, such as a breaker or fuse. Then, up to four single color or RGB underwater boat lights can be wired to it. Your lights can be controlled through a switch or light controller. Digital over-current circuits protect each light from harm.

Because the SCM-PD4CH is IP67 rated it can be mounted inside the bilge or other compartment near the lights. The lights are then wired to Deutsch style connectors that plug into the main box for a secure, watertight connection. It’s the easy way to wire underwater boat lights.
