The Digital Addressable Lighting Interface (DALI) is a two-way lighting control protocol first
released in the early 1990s. DALI was created to make commercial lighting efficient by
providing central control over fixtures.

DALI-2 is the latest version of the DALI protocol. It extends and enhances the strengths of DALI as a dedicated, standardized protocol for digital lighting control. This updated version comes with new commands and features and DALI-2 certification program significantly increases product interoperability through rigorous testing and verification methods.  

DALI-2 is known for:

• Simpler wiring
• Cross manufacture compatibility
• Standardisation of products and devices
