DALI luminaires

DALI luminaires

The DALI Alliance does NOT operate a certification program for luminaires.
Trademark use is permitted for luminaires that use DALI-based components.

To use the Trademarks, the luminaire supplier must be a member of the DALI Alliance.

Our Luminaire Brands page shows the brands that are entitled to use the DALI Trademarks on their luminaires.

Community membership is FREE for luminaire makers. >> Find out more


DALI-2 and D4i luminaires

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.

  • DALI and DALI-2 luminaires must meet the requirements of the "Trademark Guidelines" document for DALI Alliance members. 

Luminaires containing certified D4i components (which are listed in the online Product Database) are allowed to use the D4i Trademarks, including the D4i logo.


When can the DALI version-1 logo be used?

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.

When can the DALI-2 logo be used?

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.
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. This is currently possible only if the sensor is a single master.
A luminaire with an internal LED driver that can be separately tested, and an integrated sensor. Both the driver and the luminaire/sensor assembly have to be DALI-2-certified.



Zhaga-D4i luminaires

The Zhaga-D4i certification program 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.

Control devices

  • D4i control devices are listed in the DALI Alliance product database. D4i certification is required before Zhaga-D4i certification can go ahead.
  • Zhaga-D4i control devices are listed in the Zhaga product database.
