Testing - Digital Illumination Interface Alliance

Test equipment

Testing for DALI-2 compliance (including D4i) is carried out using ProbitLab test equipment, together with ProbitBench software. Both ProbitLab and ProbitBench are developed, owned and distributed by Lichtvision Engineering.

DiiA members are supplied with software Test Sequences that enable compliance testing. These test sequences are plugins for ProbitBench.

There are two different versions of the testing hardware: ProbitLab (no longer available) and ProbitLab2.

End of support for ProbitLab

Support for the ProbitLab test platform ended on 29 February 2024. The ProbitLab2 is now required for DALI testing.

Although no longer supported for official testing, there has been no deliberate action to prevent the ProbitLab from working with the test sequences, so use for development purposes can continue. However, such results will not be accepted for product certification. Some tests will not properly execute due to limitations of the ProbitLab.

Additional test equipment

Various other equipment is required, depending on the types of products to be tested. Our Product Submission Guide gives members full details. To allow further test automation, a PicoScope 4444 from Pico Technology is used together with the ProbitLab2. This also requires suitable probes. Automated testing with this became mandatory from test sequences version 2.8.0.0.

Colour control gear implementing tunable white (colour type Tc) or xy-coordinate require colour measurements as part of the tests. These measurements can be automated by use of a suitable USB-connected colour meter. Currently, several meters from Gigahertz-Optik are supported: CSS-45, MSC15, BTS256-EF, or LIGHTmetric ONE.

An nRF52840 USB dongle from Nordic Semiconductors is required for DALI+ testing, in addition to the ProbitLab2 and other test equipment. Further details are given in the Product Submission Guide.

DALI Test Houses

Member companies can carry out the required tests for each product, or they can use the services of DALI test houses that are accredited by the DALI Alliance (DiiA).

Test sequences (software)

Test-sequence software for DALI-2, D4i and DALI+ testing is developed by DiiA’s Technical & Certification Work Group (T&C WG), and supplied to DiiA members.

>> Download test sequences (DiiA members only)

Test sequences for DALI-2, D4i and DALI+ testing are based on the IEC 62386 series of standards and DiiA specifications.

To achieve certification, a product must show compliance with each specification (Part) that is implemented.

The DALI-2, D4i and DALI+ certification program will be expanded through the development and release of new test sequences, according to the priorities determined by DiiA members.
