The controller, wiring, power supply, and user interface must also be considered.

Lights must be driven cleanly with clear zones and properly sized power supply. The \u003ca href=\"\/en\/collections\/controle-eclairage\" title=\"Boat lighting controls\"\u003elighting controls collection\u003c\/a\u003e includes the control elements that can accompany this type of installation.\u003c\/p\u003e\n\u003ch3\u003eThrough-hull installation: critical points\u003c\/h3\u003e\n\u003cp\u003eInstalling a through-hull light requires serious hull work, typically with the boat out of the water. Before selecting a model, verify hull thickness, drilling zone, interior access, space for the driver or controller, cable routing, and maintenance feasibility. An installation below the waterline leaves no room for approximation.\u003c\/p\u003e\n\u003cp\u003eThe exterior location affects light output. Too high, the light illuminates the water poorly. Too close to an appendage, propeller, rudder, or water intake, it may be masked, exposed to turbulence, or difficult to maintain. Also consider cleaning, compatible antifouling, and future access from inside the boat.\u003c\/p\u003e\n\u003ch3\u003ePower, beam, and number of lights\u003c\/h3\u003e\n\u003cp\u003eLight output must match boat size and desired effect. A single high-power light does not always replace multiple well-distributed points. Underwater light diffusion also depends on water clarity, chosen color, installation depth, and beam angle. For a uniform result, plan the overall layout rather than an isolated product sheet.\u003c\/p\u003e\n\u003cp\u003eRGB or multicolor systems allow different ambiences but require suitable control. If the goal is simply functional white lighting at the stern, the installation will not be designed the same way as for a colored ambience around the entire hull.\u003c\/p\u003e\n\u003ch3\u003eWiring and electrical protection\u003c\/h3\u003e\n\u003cp\u003eWiring must be sized according to voltage, power, and cable length. Drivers and controllers should be installed in accessible, if necessary ventilated, areas protected from direct moisture and clearly labeled. Each circuit must have appropriate protection and routing that minimizes chafing, water ingress points, and mechanical stress.\u003c\/p\u003e\n\u003cp\u003eDocument the installation: locations of lights, cables, fuses, controllers, hubs, and controls. This simplifies maintenance, especially when the boat changes owners or an intervention is needed out of season.\u003c\/p\u003e\n\u003ch3\u003eComplementary collections\u003c\/h3\u003e\n\u003cp\u003eTo complete or compare the installation, also see the \u003ca href=\"\/en\/collections\/projecteur\" title=\"Boat lights\"\u003elights collection\u003c\/a\u003e, the \u003ca href=\"\/en\/collections\/eclairage\" title=\"Boat lighting\"\u003elighting collection\u003c\/a\u003e, and the \u003ca href=\"\/en\/collections\/controle-eclairage\" title=\"Boat lighting controls\"\u003elighting controls collection\u003c\/a\u003e.

It must be mounted on a flat surface (transom or hull side) at a depth of 150–250 mm below the minimum waterline. For optimal results, a spacing of 0.8 to 2 meters between lights is recommended. For wooden, metal, or carbon fiber hulls, an isolation kit is required. Bolt torque must not exceed 3 Nm \/ 26 in-lbs. Each light comes with a 3m cable and preinstalled connector, while the external driver includes a 1m power cable, with extensions available. All Lumishore products are recommended for DC system bonding via a bonding strap for galvanic protection unless the light is fully immersed fore and aft.
