Zhaga is a global lighting-industry consortium that aims to standardize LED light engines and associated components, and to simplify LED luminaire design and manufacturing. Use of Zhaga specifications can provide benefits such as the ability to keep pace with rapid LED technology evolution, flexibility to respond to customer/market requirements, and improved supply-chain management. Zhaga is creating a set of Interface Specifications, known as Books, which define the conditions necessary for interchangeability. Each Book defines an LED light engine and/or associated components by means of the mechanical, photometric, electrical, thermal, and control interfaces between the product and its environment. Products based on several of the Zhaga Books are already in common use in the global lighting market. Zhaga continues to develop new specifications that reflect the needs of luminaire makers and other stakeholders. Zhaga members share their technical expertise in an open, cooperative manner. The consortium is market-oriented and works in the best interests of lighting-industry stakeholders.
