The DALI Alliance does NOT operate a certification program for luminaires. |
Trademark use is permitted for luminaires that use DALI-based components. |
Our Luminaire Brands page shows the brands that are entitled to use the DALI Trademarks on their luminaires. |
To use the Trademarks, the luminaire supplier must be a member of the DALI Alliance. Community membership is FREE for luminaire makers. >> Find out more |
Luminaires containing certified DALI-2 components (which are listed in the online Product Database) are allowed to use the DALI-2 Trademarks, including the DALI-2 logo.
Luminaires containing certified D4i components (which are listed in the online Product Database) are allowed to use the D4i Trademarks, including the D4i logo.
The DALI-2 logo indicates that all components in the luminaire are DALI-2 certified. This means that all components that have an IEC 62386 control interface and can be separately tested are DALI-2 certified, and are listed on the DiiA website. The table below gives examples of luminaire types and DALI-2 logo usage.
Luminaire type | DALI-2 logo usage (DALI Alliance membership is required) |
A luminaire where the only DALI component is an internal LED driver (control gear) that can be separately tested. | If the driver is DALI-2 certified, then the luminaire can carry the DALI-2 logo. If the driver is replaced with a non-certified driver then the DALI-2 logo must be removed from the luminaire. |
A luminaire where the only DALI component is an integrated driver that cannot be removed for DALI-2 testing. | The whole luminaire must be tested for DALI-2 compliance. The luminaire maker must join DiiA as a Regular or Associate member. The luminaire with its integrated driver must be listed as certified in the product database. |
A luminaire with an external driver. | The DALI-2 logo can only be used if the luminaire is always sold with a DALI-2 driver. |
A luminaire containing a DALI driver and a DALI sensor that can both be tested separately. | Both components must be DALI-2 certified to allow the luminaire to carry the DALI-2 logo. |
The D4i trademark logo can be used on a luminaire that meets several additional requirements, compared to DALI-2. Details are given in the members' document "D4i Certification and Trademark Use", with an overview given in the table:
D4i luminaire requirements | |
Driver type | LED drivers bearing the D4i Trademark and listed as D4i certified in the product database. |
Number of drivers | 1-4 |
Luminaire data | Important luminaire data is pre-configured in memory bank 1 of the driver(s). |
Non-D4i drivers | Not permitted, except for emergency control gear. |
Control devices (in or attached) | If included, they must be listed as D4i certified in the product database. |
AUX supply (24V) | Required if there is at least one receptacle allowing retrofitting of control devices, where the receptacle has a pin for 24V. |
Connection to external DALI bus | Permitted, provided the DALI terminals and the bus power supply currents are correctly marked. |
Bus power supplies | Default is "enabled". Additional labeling requirement allows these to be pre-configured to "disabled". |
The DALI trademark logo can be used on a luminaire that contains at least one DALI product that meets the requirements for DALI version-1 product registration.
The Zhaga-D4i certification program for luminaires is run by Zhaga. Qualifying luminaires are able to use the Zhaga and D4i logos together on a product.
>> List of certified Zhaga-D4i luminaire product families (Zhaga website)
Zhaga-D4i luminaires contain LED drivers meeting the D4i requirements, and also have a powered Zhaga receptacle, which can accommodate a sensor or communication node with a corresponding Zhaga plug. >> More on Zhaga-D4i
Within a product family, the Zhaga and D4i logos can only be used on compatible luminaires. The family may include luminaires that do not include Zhaga connectors, and are therefore not compatible with the Zhaga-D4i requirements.
Compatible (certified) Zhaga-D4i luminaires may have one or two Zhaga sockets, or may have a hybrid configuration of one Zhaga Book 18 socket and one ANSI C136.41 socket.
