Mazha Lighting System 5.0 is a minimal lighting system created by Hangzhou-based designer Mario Tsai. Mazha Lighting System, having been upgraded and expanded over four systems, has placed greater demands on the modular system integrity and construction diversity of 5.0. Mazha Lighting System 5.0 uses the low voltage to point and modalisation of the Mazha Light as its basic principle, and the scaffolding in urban construction as its structural inspiration, which also stems from Mario Tsai’s observation of the calm but warm light coming through the scaffolding system. The straight lines formed at 90 degrees to each other can grow infinitely in three dimensions, and the lighting tubes become part of the building blocks, building huge forms but light and airy. After the construction of Mazha Lighting system 5.0, it was hoped that the 5.0 system would be equipped with different light forms and optical responses, extending both the 5.1 reflector system and the 5.2 diffused light system.
