Create unbroken swathes of light with incredible penetration and spread with these easy-to-install underwater lights. Built for the long haul, each light features full composite sandwichconstruction, making them immune to galvanic corrosion. They also boast a proprietary scratch and UV-resistant hard coating. Due to their ultra-thin profile (.300" for the MIU15, MIU30 and.375" for the MIU60) they are running-surface mountable and slightly flexible to conform with hull contours. The surface-mount, plug-and-play design only requires a 3/8" diameter hole toaccommodate wiring. All lights include AlgaeShield lens protectors and necessary mounting screws. No external driver required.
