About Us

The Zhaga Consortium is developing specifications that enable the interchangeability of LED light sources made by multiple different manufacturers. The Zhaga specifications, known as Books, describe the interfaces between LED luminaires and LED light engines.

Zhaga's members include hundreds of companies from throughout the global lighting industry. The cooperation is governed by a consortium agreement that defines rules regarding confidentiality, intellectual property and decision making.
