Zhaga Books

Zhaga is creating a set of Interface Specifications, known as Books, which define the interface for one or more components of LED luminaires. Each Book defines the interfaces by means of its mechanical, photometric, electrical, thermal, and control aspects.


An introduction to the different Zhaga Books, their current status and their similarities and differences.

⇒ Overview of the different Zhaga Books

Certification & Testing

Products are eligible for Zhaga certification after they have been tested by Authorized Test Labs. Testing confirms that the products are compliant with the appropriate Zhaga Book.

Certified products are the only products that are entitled to carry the Zhaga logo.

Book Development

Zhaga has already developed specifications for a range of components.  

In developing new Books, Zhaga looks at the industry's requirements to reduce arbitrary variations and to provide for separation of concerns between different (branches of) industries.
