The CoeLux 45 family transforms interior spaces into immersive windows to the sky, recreating the depth, intensity, and emotional impact of real sunlight with unparalleled realism. From the wall-mounted CoeLux 45 Square, designed for spaces with limited ceiling height, to the expansive 45 HC, CoeLux’s most iconic and immersive skylight, and the compact yet powerful 45 LC, each system delivers a true perception of infinite sky and a precisely defined sun through advanced optical engineering and mirror geometry. A warm 45-degree beam naturally sculpts volumes, enhances textures, and creates a living dialogue between light and shadow, while a soft blue skylight diffusion brings visual comfort and spatial openness. Available in Sun, Sun Plus, and Sun & Moon configurations, the CoeLux 45 systems support both daytime circadian alignment and evening sensory calm, reconnecting occupants with natural light cycles even in the most enclosed environments. Integrated into Lif8 environments, they become architectural and biological anchors supporting mood regulation, cognitive clarity, spatial well-being, and long-term human performance through authentic daylight exposure.
