Blue Underwater LED Light – Through-Hull or Surface Mount, 20° Beam
The Scandvik U-12 (41431) is a blue underwater LED light built around 12 SMD2835 LEDs with a focused 20° beam angle designed to penetrate the water column and create a strong underwater glow effect. Two mounting options — through-hull or surface mount — give you flexibility based on your hull type and installation preference.
The U-12 can be installed below or above the waterline, and is also suitable for wet or dry storage areas inside the vessel. Includes stainless steel mounting screws and a 5’ power cable. SKU: 390-41431.

Best Use Case
Well suited for recreational vessels looking to add blue underwater accent lighting at an accessible price point. The 20° beam angle concentrates light downward into the water rather than spreading it wide, making it effective for creating a visible underwater glow from the dock or water surface. The dual-mount option makes it adaptable to both fibreglass and aluminium hulls.
