In the yacht interior design process, lighting is integrated early to both respond to and inform the architecture, space planning, and onboard experience. Tailored lighting designs are done that highlight key features with vertical accents, provide even ambient light via linear LEDs along corridors and divisions, deliver glare-free task lighting in functional areas, and add warmth and depth through subtle uplighting and wall-washing in cabins. This includes full layouts, intuitive switching with scene control, precise light level calculations, and marine-grade fittings selected to achieve the desired effect—whether dramatic, functional, or serene.
