What is DALI?

DALI is a dedicated protocol for digital lighting control that enables the easy installation of robust, scalable and flexible lighting networks. With DALI, you can connect individually addressable lights to form an integrated system that can be managed via a central interface.

DALI has become the standard for home and professional lighting control. With the option of broadcast, you can control many devices at one time using a single system; and with a simple configuration, each device can be assigned a separate address, allowing digital control of individual devices.

The digital nature of DALI allows two-way communication between devices so that a device can report a failure, or answer a query about its status or other information. Wiring is relatively simple; DALI power and data is carried by the same pair of wires, without the need for a separate bus cable. The polarity of the wires does not have to be observed, in contrast with 0/1-10V systems where wiring errors are common.


DALI-2 is the certification program which is based on the latest version of the DALI protocol and is developed and maintained by the DALI Alliance.
The DALI-2 certification program is designed to test and verify device interoperability and is based on the latest version of the DALI standard. The program focuses on device interoperability and includes much more comprehensive testing than DALI version-1.
