Engineered to IP65 marine grade compliance, the MS104FA is built to withstand harsh outdoor conditions. The UV-treated ASA high-impact thermoplastic construction resists sun, salt, and water exposure, ensuring long-lasting durability. A waterproof polypropylene cone combined with a super high-energy neodymium motor structure delivers reliable performance with excellent efficiency.

The included white LED grill with integrated RGB lighting adds a dynamic visual element to your setup, enhancing both style and ambiance. Optional LED controllers (DARGB8A or HXMRGBLC) allow for customizable lighting effects, making it perfect for marine environments and outdoor entertainment.
