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 filled with gell, so it won’t 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.
