Question
DALI-2 LED control gear is identified by a Device Type (DT): DT6 covers single-intensity LED, DT8 covers colour control (including Tunable White, RGB, RGBW, XY chromaticity and Tc in Kelvin), and DT0 covers fluorescent lamps (legacy).

Answer
True
The main DALI-2 Device Types are: DT0 fluorescent (T8/T5, legacy), DT1 emergency lighting, DT2 HID (sodium, mercury), DT4 incandescent, DT6 simple LED gear, and DT8 LED colour (Tunable White, RGB, RGBW, XY, Tc). A modern LED luminaire control gear typically implements DT6 and DT8 simultaneously to expose both intensity and colour from the same device.
Preparation tip
When you query a luminaire, check for multiple Device Types in the response — a 'DT8 only' driver still needs DT6 commands for plain dimming, so most products advertise both.

- DALI-2 (IEC 62386 Edition 2, 2014+) is the major evolution of DALI v1, adding native support for input devices (sensors, push-buttons) directly on the DALI bus itself, together with a product certification programme administered by the DALI Alliance (DiiA).1. Architecture · DALI vs DALI-2
- The DALI bus uses a polarity-free twisted pair (no + / - orientation), with Manchester coding at 1 200 baud over a nominal 22.5 V DC supply, and is allowed to share the same multi-core cable as the 230 V mains feeding the luminaires.1. Architecture · Physikalische Schicht
- Self-contained emergency luminaires (DT1) under DALI-2 support standardised commands for the monthly function tests and annual duration tests required by EN 50172, and these tests can be automated from a central DALI-2 controller.2. Devices · Typ 1 Notbeleuchtung
- DALI-2 supports several application controllers active on the same bus (multi-master), with an arbitration mechanism that prevents conflicts when two controllers try to command the same control gear at the same time.4. Application Controllers · Multi-Master
- DALI bus power supplies are typically available at 100, 120, 150 or 250 mA depending on the vendor (ABB BCO/S, Tridonic DALI-PS, Lunatone PS5), and should be sized for the cumulative current of control gear plus input devices, with a 30 percent margin.7. Best practices · Bus-Netzteil
