About the DALI Alliance

Welcome to the DALI Alliance

The DALI Alliance (also known as the Digital Illumination Interface Alliance, or DiiA) is the global industry organization for DALI lighting control.

We are an open, global consortium of lighting companies, and our main aim is to grow the market for lighting-control solutions based on the standardized Digital Addressable Lighting Interface (DALI) protocol.

The DALI Alliance was established in response to industry requests for an independently-verified certification program that covers the functionality specified in DALI-2, the latest version of the DALI protocol.

DALI-2 product certification by the DALI Alliance brings the promise of significantly-improved interoperability and additional functionality compared with the current DALI systems in the market.

Products that have successfully completed the DALI-2 certification process are eligible to use the DALI-2 logo trademarks. Only certified products can carry the DALI-2 logo, and only DiiA members can certify their products. 

>> All DALI-2 products are listed in the Product Database

The DALI Alliance develops the Test Specifications that allow companies to test their products for compliance with DALI-2 requirements. The DALI-2 Test Specifications are derived by DiiA from the multi-part IEC 62386 standard or from DiiA specifications.

The DALI Alliance was formed by seven leading lighting companies: Erco, Helvar, Insta, Lutron, Osram, Philips Lighting and Tridonic.
