DiiA: The global industry alliance for DALI® lighting control

The Digital Illumination Interface Alliance (DiiA®) is an open, global consortium of lighting companies that aims to grow the market for lighting-control solutions based on Digital Addressable Lighting Interface (DALI®) technology.

Building on the long-established benefits of DALI, the DALI-2 certification program brings the promise of significantly improved interoperability and additional functionality compared with current DALI systems in the market. And the new D4i™ certification program brings standardization to intra-luminaire DALI.
