An inventive solution directed to an apparatus and system for creating a dynamic ambient lighting experience wherein the level of brightness increases and decreases along a horizonal path to create an impression of linear movement. This simulates the traversal of the sun along its horizon. The device comprising subsection units which may be coordinated to increase or decrease length. The time and speed for dimming and brightening of light from start to finish along the length of the device may be defined by preconfigured parameters or customized to desired setting. The device creating a diurnal pattern of light transition and movement along the length of an indoor space subject to the peripheral view of the observer.
