Zhaga Book 18 and Book 20

Zhaga is an international organization that standardizes specifications for components used in LED luminaires.

Zhaga Book 18 defines a standardized interface for outdoor luminaires, focusing on the mechanical and electrical aspects to ensure interchangeability between different manufacturers' smart control products.

While Zhaga Book 20 specifies a standardized interface for indoor luminaires, also emphasizing mechanical electrical and communication aspects.

Both standards aim to promote interoperability and simplify the design and manufacturing processes for lighting products.

Zhaga Book 20 defines a smart interface between an indoor LED luminaire and a sensing/communication module or control device, it brings together complementary specifications from the Zhaga Consortium and the D4i specifications from the DALI Alliance.

It provides a simple way to add control devices to luminaires by providing a standardized interface between them.
