Digital Addressable Lighting Interface (DALI) is a trademark for network-based products that control lighting.

The underlying technology was established by a consortium of lighting equipment manufacturers as a successor for 1-10 V and DSI (Digital Serial Interface) lighting control systems, and as an open standard alternative to several proprietary protocols. The DALI, DALI-2 and D4i trademarks are owned by the lighting industry alliance, DiiA (Digital Illumination Interface Alliance). Prolojik is a member of DiiA.
Our Modular, Plexus, Indigo and Lightmatrix products support DALI, DALI-2 and D4i standards.

DALI is specified by a series of technical standards in IEC 62386. Standards conformance ensures that equipment from different manufacturers will interoperate. DiiA has released standards for a variety of products including LED drivers, emergency inverters, tuneable white drivers and a number of sensors.
