DALI-2

What is the difference between DALI and DALI-2?

View answer

DALI-2 refers to version 2 of IEC 62386, the international DALI standard, and was introduced in late 2014. For DALI-2, the standard was restructured for ease of use, and many improvements were made including the addition of new commands and features. DALI-2 was created with a focus on multi-vendor 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

While DALI-2 exists, other terms such as “DALI-8” do not exist. This is a mistaken reference to “device type 8” which relates to devices that are described in Part 209 of IEC 62386; these devices are control gear with colour-control capabilities.

Close

When will tests for sensors be ready?

View answer

Test procedures for different product types are developed by the DiiA Test & Certification Work Group, who also carry out beta testing before these are released to members. The process relies on the participation of member companies. Priorities are determined by the members. Our website (www.dali2.org/dali/standards.html) shows the current status of the different Parts of IEC 62386 and the corresponding test sequences, including those for sensors.

Close

Can colour control gear (Part 209) be tested?

View answer

There are no Part 209 tests in DALI version-1, and the Part 209 tests for DALI-2 are not yet available. An exemption is currently in place which allows DALI version-1 testing of colour control gear for all Parts except Part 209. However, the company must state that “the DALI colour-control functionality (Part 209/Device Type 8) of this product has not been verified.”

Close

Is DALI training available?

View answer

Yes, DiiA provides training to member companies, for an additional fee. Subject areas can be tailored to a member’s specific needs. Please contact DiiA for more details.

Close

Will there be a Plugfest?

View answer

DiiA organizes “Plugfest” meetings, which currently are used primarily to check test sequences. These are open to Regular members of DiiA only. In future, Plugfest events will also allow members to check the interoperability of their products with those of other companies.

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. For this purpose, companies can register via the DiiA website; 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 version 2 of the IEC 62386 standard for DALI technology, and involves verification of test results via a robust web-based tool. 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.digitalilluminationinterface.org/products).This page can be used to check the status of DALI-2 certification, or DALI version-1 registration. Products not appearing in the list are not DALI-2 certified.

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?

View answer

DiiA was formed in response to industry calls for a global, open, not-for-profit certification program based on the latest version of IEC 62386. It was felt that a new alliance was the best way to enable companies to bring their next-generation, certified DALI products to market in a timely and efficient manner.

Close

What happened to the DALI-AG working party?

View answer

ZVEI, the German Electrical and Electronic Manufacturers' Association, provided a range of services related to DALI version-1 through its DALI working party (also known as DALI-AG). This organization was dissolved by ZVEI in late March 2017. There are no organization links between ZVEI and DiiA. The DALI trademarks and logos were acquired on behalf of DiiA from ZVEI. Former members of DALI-AG do not retain any rights to use the DALI trademarks unless they join DiiA.

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 (TCWG) and the Promotion Work Group (PWG). The TCWG hosts face-to-face meetings and “Plugfest” events. Only Regular members can participate in work groups (TCWG, PWG). All members – Regular and Associate – can attend General Assembly meetings, which are held annually.

Close

Who is driving the development of new specifications?

View answer

IEC is responsible for authoring, reviewing and editing the various parts of the DALI standard (IEC 62386). Lighting experts from different countries contribute to this IEC working group. Anyone wishing to participate should contact their national IEC committee. DiiA is responsible for maintaining and developing test procedures for the different Parts of the standard. In addition, DiiA is developing new specifications that are related to the DALI protocol.

DALI Version-1

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

View answer

Yes, DiiA provides a program for its members that supports self-declaration and registration of products that have been 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

Control devices, including input devices (e.g. occupancy sensors, push buttons etc) and application controllers (the brains of a DALI system) 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. DALI-2 certification of these product types will become available in due course.
