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.
