The Module-Driver interface Special Interest Group (MD-SIG) is a global lighting-industry consortium which has published a specification for a standardized, multi-vendor electrical interface between LED drivers (control gear) and LED modules.
MD-SIG and Zhaga are separate organizations. Please consult the MD-SIG website for up-to-date information.
MD-SIG specifications can be downloaded from the MD-SIG website.

Enabling LED modules and LED drivers to be fully interchangeable at the component level requires a specification for the electrical interface between the driver and module (DMI). Arnulf Rupp of OSRAM GmbH, a member of both the Zhaga Consortium and MD-SIG, explains the role of both organizations in developing and implementing a consistent, easy to use, cross-vendor DMI specification.

Book 11 is the first Zhaga Book to contain a reference to the LEDset specification for the electrical interface between a Book 11 LED module and a suitable driver. This so-called driver-module interface (DMI) is essential to enable the independent interchangeability of different drivers and modules.
