Shadow-Caster SCM-4

Some of the best fishing is at night. Crappie, stripers, flounder, and snook all feed better in the cool of the evening. And every decent fisherman knows a good pair of lights makes them bight even hotter.

SCM-4 single color underwater lights for boats under 18 feet are compact and mega bright. They come in 5 colors, Bimini Blue, Ultra-Blue, Aqua Green, Great White, and Cool Red, so you can choose the color that best fits your needs.

The SCM-4 produces 1,000 lumens of light in white while drawing a measly 1.4 amps of current at 12 volts. Now you can fish all night without draining your battery!

Tough Underwater Lights for Boats?

Boating is tough on lights. Pounding waves, corrosive saltwater, and the high voltage spikes that plague marine electrical systems will destroy lights not engineered to take the abuse.

That’s why the engineers at Shadow-Caster design all of their lights to withstand the severe punishment of the marine environment.

Shock Resistance

LED lights are extremely shock-resistant. They are immune to the tremendous forces created by pounding waves.

316 Stainless Steel Housing

Shadow-Caster SCM series lights are made from 316 Stainless Steel. 316 Stainless Steel won’t stain, pit, or corrode even in saltwater. The stainless steel housing also aids in removing heat from the LEDs allowing them to shine brighter and last longer.


High Voltage Spikes plague marine electrical systems. Every time you start your motor or a pump or other electronics turns on or off a spike of high voltage can shoot through your electrical system. This can damage poorly protected LED lights causing them to fail. Shadow-Caster LEDs use only the most advanced electronics to protect their lights.

  • Advanced electronics automatically disconnect Shadow-Caster LEDs if a voltage spike or reverse polarity is detected.
  • Thermal Protection circuits protect the lights from overheating.

Great Looks

Shadow-Caster LEDs are more than just the toughest lights in the water they are the best looking as well.

  • Great looking surface mount design that is only 1/2 an inch thick.
  • 120 degrees light spread floods the water with light.
  • 5 vibrant colors.

Operating The SCM-4

Shadow-Caster single color lights are operated through a simple On/Off Toggle switch.

The toggle switch is included in your order. It allows you to turn single color lights on and off.
