What Is DALI-2?

DALI-2 (Digital Addressable Lighting Interface, version 2) is the latest official standard for lighting control systems. It builds on original DALI with better interoperability, more device types, and standardised features — making it easier to design, install, and maintain a smart lighting network.

It’s fully defined under IEC 62386 and supported by trusted manufacturers like Zencontrol, WAGO, Tridonic, Helvar, Osram, and Philips.

Where Is DALI-2 Used?

🏢 Office Fitouts

• Control lighting by zone, meeting room, or tenant
• Use motion + lux sensors for daylight harvesting
• After-hours dimming and BMS integration

🏨 Apartments & Lobby Areas

• Group lighting by floor, corridor, or zone
• Schedule-based automation for common areas
• Interface with KNX, BACnet, or Zencontrol cloud

🏥 Health, Aged Care & Education

• Circadian lighting for wellness
• DALI-2 emergency test logging
• Localised override + automation via WAGO or KNX

Why Does DALI-2 Matter in 2025?

Lighting is now expected to be:

• Automated (not just switched)
• Monitored (not just installed)
• Energy-efficient (with lux and presence logic)
• Integrated (with HVAC, access, or energy dashboards)

Only DALI-2 ticks all of those boxes in a standardised, future-proof way.

It reduces commissioning headaches, ensures vendor flexibility, and improves lifecycle support — especially in commercial buildings, campuses, and infrastructure projects where reliability matters.

How DALI-2 Improves on Legacy DALI

DALI-2 makes smart lighting simpler, more reliable, and easier to integrate. Unlike older DALI systems that relied heavily on proprietary logic or limited compatibility, DALI-2 is fully standardised under IEC 62386. That means every sensor, input device, and control unit is built to the same rules — no more guessing if one brand’s switch or sensor will work with another.

With DALI-2, control devices like motion sensors, switches, and scene panels are fully addressable and programmable — something legacy DALI didn’t officially support. Diagnostics are built into the protocol too, allowing for real-time monitoring of fitting failures, lamp status, or emergency light testing. That’s a big win for facility managers and maintenance teams.

Emergency lighting is another major leap forward. DALI-2 supports automated emergency testing and logging, which means no more manual checklists or wiring workarounds. It also includes application controllers, meaning scenes and group logic can be handled natively without relying on third-party add-ons.

In short, DALI-2 gives you more flexibility, cleaner commissioning, and better long-term support — especially when paired with a system like Zencontrol, WAGO, or KNX.
