2. Zhaga Books: Introduction
Zhaga is creating a series of specifications, known as Books
Each Book defines one or more components of an LED luminaire. Such components include LED light engines, LED modules, LED drivers, LED arrays, holders, and connectivity fit systems.
Books define the mechanical, photometric, electrical, thermal, and control interfaces of the component to its environment
Books define the conditions necessary for interchangeability
Zhaga has a certification program for compatible products
Third-party testing
Traceability via on-line database (
