To ensure compatibility of products, and to allow use of the DALI trademarks, it is necessary to test products using the official DALI test system.
The official test system consists of hardware and software:
- Hardware: ProbitLab or ProbitLab 2, from Lichtvision
- ProbitLab can be used for testing of control gear that does not have a built-in bus power supply. This is most types of control gear. IEC parts 102 and 201-208 are supported.
- ProbitLab 2 (contact Lichtvision for availability): can test everything that ProbitLab can test, as well as bus power supplies, control gear with integrated bus power supplies, and control devices.
- DALI test sequence software, included with DALI membership
- Periodically updated to include new parts as well as improvements and fixes for current parts
- DALI members are provided with the latest version by logging into their DALI account
DALI compliance testing can be carried out by either self-testing, or at a test house.
- Self-testing requires the purchase of a DALI test platform, ProbitLab, from Lichtvision. With this, members of DALI have access to the DALI test software that is used to show compliance of products.
- Alternatively, a test-house may be used to show compliance. The test-house must use the approved tester (ProbitLab or ProbitLab 2) and the latest DALI test sequence software.

Currently, there is no need to submit test results to DALI. Just keep the results in case of future queries. With successful test results, you may then log into the members’ area of this web site to list your compliant products, and you may apply the DALI logo to the compliant products and associated documentation. Potential customers can search the product database.
If you modify a product, including updates of firmware, you will need to re-run the DALI tests to ensure it is still compliant.
Very soon, we will have a new logo licensing process, where a summary of test results will need to be submitted. At that time, the rules for continued use of the logo on previously compliant products will be explained.
DALI 2 test sequences for control gear will be released to members soon. Shortly after release, the DALI 2 licensing process will start. Until products have successfully completed the DALI 2 licensing process, the DALI 2 trademark may not be used - either on products, product literature or marketing material.
A combination of several products that together are DALI testable, may be marked as DALI compliant on the product containing a DALI interface, provided this combination of products passes the relevant DALI tests.
In addition, the combination of products shall be specified when the test results are submitted to the DALI licence web-server (DALI 2 products) and the combination of products shall be specified in the product literature where the DALI trademark is used or DALI compliance is claimed. The entry on the licence web-server (where applicable) and product literature shall also state that "combinations of products other than those tested, may not be DALI compliant".
One such example could be a DALI PWM driver for use with LED lighting. In this example, there are two products that together can be tested as DALI control gear:
1. DALI-PWM interface. This product has the DALI interface, and also has a PWM signal output.
2. PWM-LED power driver. This additional product has an input for a PWM signal, as well as an input for mains or DC power, and provides an output to connect to LEDs.
In this example, the DALI-PWM interface cannot be tested without the PWM-LED power driver. The combination can be tested, and if the DALI tests all pass, then the DALI-PWM product may have the DALI trademark applied - provided the usual rules for use of the trademark are met. The trademarks cannot be applied to the PWM-LED power driver, because this product does not contain a DALI interface.
Note: To allow the multi-part product combination to pass, the lamp failure tests must pass. This can be a design problem for such product combinations.
Once DALI 2 product compliance is possible, further requirements for family products will be published on our website. For DALI 1 control gear testing, the following guidelines are recommended:
- A product family consists of one product that is fully tested, plus variants that are partially tested.
- Where there are no software or DALI related hardware differences between products in the family, one product shall have complete DALI testing carried out, while others have at least the dimming curve, fade times and possibly lamp error tests carried out, because these are most likely affected by having different output drive capabilities.
- Other tests that may show a difference in operation or have a higher risk of failure, should also be applied to the variants.
- If any software or hardware differences affect DALI behaviour, the product manufacturer or developer determines which functionality may be affected, and which additional tests should be applied.
- As an example: If the micro-controller is from a different series, full testing would be expected.
- Test-houses may give advice on the additional testing required for family products. Such advice must be shown on the test report.
For control gear, the additional tests referred to above, are from IEC 62386-102:2009:
- 220.127.116.11 Logarithmic dimming curve
- 18.104.22.168 Dimming curve: DIRECT ARC POWER CONTROL
- 22.214.171.124 QUERY LAMP FAILURE (if there is any difference in the hardware or software that may affect lamp error detection)
Note: It is the responsibility of the manufacturer/vendor whose company name appears on the product, to ensure that all such products carrying the DALI trademark would pass a complete set of tests. If a family product is later found to be non-compliant, then every member of the family reliant upon the same fully tested product becomes non-compliant until the issue is fixed and successfully re-tested.
For products that have previously been shown to be compliant as a result of full testing, but later have firmware or hardware changes made, then additional testing is required to allow continued use of the DALI trademarks.
The product manufacturer or developer determines which DALI behaviour or functionality may be affected by the changes, and which tests should be re-applied. Alternatively, test-houses may give advice on the additional testing required. Such advice must be shown on the test report.
