DALI-2

What is the difference between DALI and DALI-2?

View answer

DALI-2 is the latest version of the DALI lighting-control protocol. DALI-2 includes many new commands and features, and has a focus on multi-vendor product interoperability. Also, for the first time, DALI-2 includes control devices (application controllers and input devices such as sensors), which were not part of DALI version-1. Our website (www.dali2.org/dali/comparison.html) has more information on DALI version-1 and DALI-2.

What is meant by “DALI-8”?

View answer

"DALI-8" does not exist. The only versions are DALI-2 and its predecessor, DALI version-1. The term “DALI-8” is a mistaken reference to “DALI device type 8” or "DALI DT8" which relates to control gear with colour control, as specified in Part 209 of IEC 62386.

Will there be a Plugfest?

Logos and Trademarks

Who can use the DALI-2 logo?

View answer

The DALI-2 logo can only be used by DiiA members on their products that have successfully completed the DALI-2 certification process. All DALI-2 certified products are listed in the Product Database on the DiiA website. In addition, Community members of DiiA have certain rights to use the DALI-2 logo on luminaires that contain DALI-2 certified devices, in accordance with the DiiA Trademark Guidelines.

Close

Can luminaire makers use the DiiA logo if they do not certify their own DALI-based products?

View answer

Yes, DiiA supports luminaire manufacturers that do not certify products themselves but use certified DALI-2 components in their luminaire products. DiiA grants these companies a license to use its trademarks in accordance with the DiiA Trademark Guidelines. Luminaire makers can apply for Community registration; there is no registration fee or license fee.

Certification

Is there a cost involved in DiiA certification? Why?

View answer

Yes, all DiiA members must pay a certification fee for each product certified. Payment is made in advance by purchase of certification credits. This is separate from any testing costs, which the member company must pay independently. The certification fee helps to meet the costs incurred by DiiA, including: Technical support for certification; Developing and improving test-sequence software; Verification of test results; Maintaining the online submission system and product database, and building new functionality; Carrying out market surveillance to protect the value of DiiA and DALI branding.

Close

How does DALI-2 certification differ from DALI version-1 compliance testing?

View answer

The DALI-2 certification program is based on the latest version of the DALI protocol, and involves verification of test results by DiiA. In contrast, DALI version-1 compliance testing is based on self-declaration without verification of results. As well as covering many different product types, including control devices (e.g. input devices and application controllers), DALI-2 certification offers the promise of improved interoperability of products from different manufacturers.

Close

Do companies have to pay each year to renew DALI-2 certification?

View answer

No, the certification fee is a one-off cost per product. Once a product has been certified, it remains certified for as long as the company remains a member of DiiA.

Close

Where can I download product test reports or certification documents?

View answer

DiiA does not issue test reports or product certification documents. Instead, every DALI-2 certified product is listed on the public search page: (www.dali2.org/products). This page can be used to check the status of DALI-2 certification: Products not appearing in the list are not DALI-2 certified. The same applies to DALI version-1 registration.

Close

What is the cost to certify products?

View answer

The cost varies according to circumstances. DALI-2 certification is open only to Regular or Associate members of DiiA, with an annual fee of EUR 15,000 or EUR 5,000, respectively. Each certified product requires the use of one certification credit, purchased in advance. This is a one-time fee (it is not an annual charge). Many companies decide to purchase Probit hardware and other equipment for testing, but this is not mandatory. Some companies pay for the services of a test house. However, the test-sequence software is supplied free to members.

Organization

Why did you form a new alliance? What happened to DALI-AG?

View answer

DiiA was formed in response to industry calls for a global, open, DALI-2 certification program. It was felt that a new alliance was the best way to enable companies to bring their next-generation, certified DALI-2 products to market in a timely and efficient manner. DALI-AG was dissolved by ZVEI in late March 2017.

Close

Is DiiA a European organization? Who can join?

View answer

No, DiiA is not European, it is an international organization, and is open to all members of the global lighting community.

Close

When does DiiA meet, and who can participate?

View answer

DiiA holds regular telephone conferences for the different committees and work groups, namely the Board of Directors, the Technical & Certification Work Group (T&C WG) and the Promotion Work Group (PWG). The T&C WG hosts face-to-face meetings and “Plugfest” events. Only Regular members can participate in Work Groups. All members – Regular and Associate – can attend General Assembly meetings.

Close

Who is driving the development of new specifications?

View answer

DiiA drives the DALI-2 certification program, and develops and maintains DALI-2 Test Procedures for the different Parts of the IEC 62386 standard. In addition, DiiA develops new specifications for new features and functions. IEC is responsible for authoring, reviewing and editing the various parts of IEC 62386. Lighting experts from different countries contribute to this IEC working group. Anyone wishing to participate should contact their national IEC committee.

DALI Version-1

Will you continue to support the DALI version-1 self-declaration program?

View answer

Yes, until further notice DiiA enables members to register products (control gear only) that have been self-tested for compliance with DALI version-1. DiiA members are able to use the current DALI version-1 logo on products.

Close

Do I have to list my DALI version-1 products on the DiiA website?

View answer

Yes, registration of DALI version-1 products and listing on the DiiA website is now compulsory, effective from June 1st, 2018. This applies to new products, and also to existing DALI version-1 products that continue to be available to the market.

Close

Can I use the DALI version-1 logo on control devices?

View answer

No. Control devices, including input devices (e.g. occupancy sensors, push buttons etc) and application controllers were not included in version 1 of the DALI standard. Therefore, it is not possible to use the DALI version-1 logo on these products. But DALI-2 certification of these product types is now available.
