Digital addressable lighting interface (DALI) is a dedicated lighting control protocol for intelligent lighting systems that is widely used in commercial lighting control and building lighting control. DALI-2 lighting control enables network-based lighting control for building automation applications that are designed for compliance to IEC 62386 Version 2 (DALI-2) when used with suitable hardware. The DALI-2 standard improves on the ability to control brightness, glare, color rendering, and presence detection, and adds multi-vendor interoperability to the DALI standard IEC 62386.
