Equal Interval (Isophase) Light

Equal Interval, often referred to as Isophase light, is a specialized form of lighting that employs a rhythmic pattern wherein the light and dark periods are precisely equal. This characteristic creates a unique visual effect, drawing attention to the regular oscillation between illumination and shadow.
