DALI 2The newer DALI-2 standard also covers switches, multi-sensors, bus power supplies, and control systems in addition to luminaires or ECGs. DALI-2 devices must be certified by the Digital Illumination Interface Alliance (DiiA) to be entitled to carry the DALI-2 logo.The DALI-2 certification promises significantly improved interoperability and additional functionality compared to older DALI systems on the market (version 1). LOYTEC recommends to use preferably DALI-2 certified devices. DALI and DALI-2 devices can be used simultaneously within one DALI channel.
