DEXAL® Technology

Where efficiency, productivity, simplicity and interoperability intersect. DEXAL® Technology—a North American exclusive technology—leverages one interface for designing compatible luminaires for intelligent systems, extracting fixture-specific data and increasing productivity.

What Is DEXAL® Technology?

DEXAL® Technology by eldoLED is a non-proprietary, intra-luminaire interface based on DALI. It provides bi-directional communication and power between an OPTOTRONIC® by eldoLED DEXAL LED driver and a fixture-integrated component.


DEXAL (DALI) Technology is a simplified option of creating smart, connected fixtures that are compatible with industry-leading light management systems. Perfect for supporting future data-driven applications that require precise luminaire data.

The First In The Industry

We’re the first in the industry to achieve D4i certification on both indoor and outdoor DALI/DEXAL LED drivers (indoor: OTi30, OTi50, OTi85 and outdoor: OTi60). The D4i certification of our DALI/DEXAL LED drivers allow for new opportunities to create smart, connected fixtures when paired with D4i certified sensors. Our DEXAL Partners and their sensors are certified by eldoLED.


Manufacturers that adopt OPTOTRONIC drivers with DEXAL (DALI) can support multiple projects requiring bi-directional communications using one driver. It’s that simple. One driver for multiple projects—even if each project specifies a different light management system. 

Meet Our Partners

Work with a DEXAL Partner for certified system compatibility with their fixture integrated components and our OPTOTRONIC LED Driver with DEXAL Technology. DEXAL Technology allows luminaire manufacturers to easily design-in components that support multiple light management systems (LMS). Providing a wider variety for light specifiers and agents to choose the best LMS system and luminaire for their project.


We're proactively working with our partners in developing smarter fixtures for the future.

How DEXAL Technology Benefits Luminaire Manufacturers

DEXAL enables a streamlined means of designing luminaires that are both smart and compatible with multiple light management systems, thereby increasing productivity.


By utilizing an OPTOTRONIC LED driver with DEXAL Technology (based on DALI), manufacturers can build smart fixtures that support various light management systems (LMS).

How DEXAL Technology Benefits Agents

DEXAL Technology provides you with one interface that’s supported by multiple light management systems (LMS). Here’s some additional perks:

  • Communicate bi-directionally with the DEXAL non-proprietary DALI interface

  • Create smart connected luminaires (smart nodes) compatible with various LMS systems

  • Set up Luminaires for future smart building applications (based on DALI interface)

How DEXAL Technology Benefits End Users

The DEXAL interface allows end users to extract valuable fixture-specific data for predictive maintenance.  

  • Turn your fixture into a smart node on a lighting control network

  • Extract valuable fixture-specific data for maintenance service including:

    • Power and energy consumption

    • Temperature profile

    • Operating hours

    • Diagnostics and more
