CoeLux Sky Spot and Sky Line bring the true essence of natural daylight into interior environments, transforming spaces with little or no access to sunlight into biologically supportive, emotionally uplifting ecosystems. Using CoeLux’s patented Rayleigh scattering technology, these architectural lighting solutions faithfully replicate the optical and spectral behavior of real sunlight and sky, creating a light experience that feels instinctively natural to the human eye and nervous system. Sky Spot delivers a refined downlight effect either as a standalone solution or in synergy with CoeLux skylights reproducing the delicate balance between sunlight and skylight, while the Dynamic version introduces Tunable White technology to support circadian-aligned lighting from morning to evening. Sky Line extends this experience vertically, projecting a soft yet powerful band of sunlight onto walls, enhancing spatial perception, depth, and visual comfort. Fully compatible with smart control systems, both solutions play a critical role in regulating circadian rhythms, improving sleep quality, cognitive performance, mood, and stress resilience.
