Lighting system is constituted by reinforcement and permanent lighting. The first one thanks to a high counter-beam optics with superior lighting engineering features, is designed from a viewpoint of energy efficiency and safety.
About the permanent lighting, throughout the patented technology by Arianna, the product’s glare level is very low, barely amounting to a fifth of the legally acceptable limit, obtaining high visual comfort.
In addition, the technology used provides for more economical spacing.
