Shadow-Caster SCM-PD4CH is a four channel marine power distribution box for underwater boat lights. It greatly simplifies wiring of up to four single color or RGB/RGBW underwater boat lights. 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.
