Shadow-Caster SCM-4


The Shadow-Caster SCM-4 is a single color, surface mount, underwater LED light for boats. Its compact size makes it a great choice for fishing boats, day cruisers, and pontoon boats under 20′ or boats up to 23′ on a budget.
The SCM-4 is built to last with a corrosion-free stainless steel body and internal circuitry that protects it from voltage spikes, reverse polarity, and overheating. It’s even gel-filled so it will never leak.
At 1,200 lumens, the SCM-4 is one of the brightest 4 LED lights in the water. It comes in five beautiful colors, making it easy to find the perfect color for your boat.
