DALI-2 certification supports interoperability
06 June 2022
THE DALI Alliance is strengthening its focus on the DALI-2 product certification programme, including D4i, after ending registration of DALI version-1 control gear.

DALI-2 certification builds confidence in the interoperability of DALI-based devices from different manufacturers. As a standardised platform, DALI-2 mitigates concerns around proprietary technologies and vendor lock-in, and enables future-proof luminaire and system designs for sustainable lighting.
Driven by the DALI Alliance and building on the requirements of the international IEC 62386 standard, DALI-2 certification requires rigorous product testing. The test results are independently verified by the DALI Alliance. In contrast, DALI version-1 testing was less detailed and relied on self-declaration, without requiring third-party verification of test results.
DALI-2 certification is now available for all control gear types in common use, including those for colour control and self-contained emergency lighting. DALI-2 also includes a broad range of additional features such as storage and reporting of luminaire, energy and diagnostics data.
