The Zhaga Consortium recently released Edition 4 of Book 18, the most widely adopted specification in the Zhaga portfolio and a cornerstone of its certification program. This new edition extends the Zhaga-D4i ecosystem to support heritage and decorative luminaires, addressing the growing need for smart, connected and circular lighting solutions across outdoor and industrial environments.
Zhaga Book 18 “Smart Interface Between Outdoor Luminaires and Sensing/Communication Modules” defines a standardized mechanical interface, intra-luminaire communication protocol, and power budget for control devices such as sensors and communication nodes. It provides the foundation for interoperable, serviceable, and upgradeable outdoor lighting systems, forming the backbone of modern smart and sustainable city infrastructure.
Edition 4 introduces important updates designed specifically for applications where traditional luminaire designs must meet today’s digital requirements. It now:
• Allows pole-mounted bracket assemblies, making smart connectivity possible for heritage and decorative luminaires with diverse shapes and forms.
• Addresses installation challenges by supporting longer connection cables between the luminaire and bracket assembly, while ensuring robust and reliable communication across these extended distances.
• In the context of the joint Zhaga-D4i certification program developed together with DALI Alliance, defines surge protection functionalities for this specific configuration, ensuring reliability in demanding environments.
Book 18 Edition 4 is now available to all Zhaga Regular and Associate Members through the Zhaga member portal.
