DALI: The standard for smart lighting control in the IOT era

The DALI Alliance is the global industry organization for DALI®, the internationally-standardized protocol for digital communication between lighting-control devices. DALI is the Digital Addressable Lighting Interface. 

 Building on the long-established benefits of DALI, the DALI-2 certification program brings the promise of significantly improved interoperability along with more features and functions including sensing and data gathering. Meanwhile, D4i™ enables DALI for intelligent, IoT-ready luminaires and sets the scene for different connectivity options over wireless and IP-based networks.
