What is DALI-2?

Digital Addressable Lighting Interface (DALI) has been the professional lighting control standard since 2001. DALI-2, introduced in IEC 62386 Part 2, extends the original specification with strict interoperability testing requirements — meaning any two DALI-2 certified devices from different manufacturers are guaranteed to work together.

Key Improvements Over DALI-1

The most significant improvements include: standardised device discovery and commissioning, input device support (sensors, switches, and push-buttons as first-class DALI devices), enhanced diagnostic reporting, and mandatory certification testing by an accredited laboratory.

For system integrators and building owners, this means reduced commissioning time, better system diagnostics, and genuine future-proofing.

Specifying DALI-2 in Indonesia

TDE supplies DALI-2 certified luminaires from Helvar, Lutron, Zumtobel, and ERCO. Our lighting control specialists can assist with system design, device selection, and commissioning — ensuring your project achieves the full benefits of intelligent lighting control.

The Efficacy Milestone

For context, a standard incandescent lamp produces around 15 lm/W. The leap to 200 lm/W represents a 13x improvement in raw efficiency. In practical terms, a 10W luminaire can now produce as much light as a 130W incandescent — dramatically reducing energy costs and cooling loads in large commercial installations.

Impact on Green Building Ratings

Indonesia's Green Building Council (GBCI) rating system awards points for lighting power density (LPD) below defined thresholds. At 160+ lm/W commercial efficacy, projects can achieve LPD levels below 5 W/m² in offices — easily surpassing Greenship requirements and qualifying for maximum lighting energy credits.
