Shadow-Caster SCM-4


Shadow-Caster SCM-4 are single color surface mount LED underwater lights for boats. This compact light is a great choice for small boats with a narrow beam, as a side light on larger boats, or when you want a bright, long lasting light that won’t break your budget.
The SCM-4 is built to last with a stainless steel body and internal circuitry that protects the lights from voltage spikes, reverse polarity, and overheating. This allows the SCM-4 to shine bright at up to 1,200 lumens. It comes in five beautiful colors making it easy to find the perfect color for your boat.
