Aqualuma Gen IV Thru-Hull Underwater Lights boast an incredibly strong, one-piece, impact-resistant polymer housing. They can be purchased as a complete assembly (light module with thru-hull case) or as an upgrade that fits into a previously-installed Aqualuma Gen I, II or III thru-hull case. Unlike surface-mount underwater lights, Aqualuma Thru-Hull Underwater Lights can be replaced or upgraded from inside the boat—there is no need to haul out. Lights feature 8x standard and 4x wide angle elliptical optics which create a deep penetrating and wide flat beam of light. Installation is facilitated by the simple two-wire connection to power and each light includes 12' of tinned wire cable. No bonding or anodes are required. *Pictured image is of 12-LED light.
