DALI LED Controllers – RGBWA 5CH (DT8)

DALI RGBWA 5CH: digital control for RGB + tunable white with DT8

Standard

DALI RGBWA 5-channel controllers and drivers allow the combined management of red, green, blue, and warm/cool white LEDs through the DALI/DALI2 protocol. Based on DT8, these devices integrate RGB and CCT regulation into a single address, simplifying configuration and ensuring superior light quality. They provide high luminous power, advanced chromaticity, and great flexibility, suitable for both dynamic multicolor scenarios and functional/adaptive lighting.

System architecture

  • DALI RGBWA devices: 5CH modules (RGB + CCT) for integrated management.
  • DALI/DALI2 LED drivers (DT8): constant voltage (CV) or constant current (CC) versions for RGBWA loads.
  • DALI wall panels: touch or slider controls for 502/503 flush-mounted boxes to adjust color, intensity, and tunable white tones.
  • DALI Push Button Couplers: enable local management with traditional push buttons.
  • DALI/DALI2/D4i relays and sensors: auxiliary load control and presence/light detection.
  • Multi-protocol compatibility: integration possible via DALI/DMX or DALI/RF gateways.
  • DT8 unique addressing: simplified management of multiple channels through a single DALI address.
  • Multi-point/multi-zone topology: centralized or distributed control of multiple RGBWA loads on the same bus.

Advanced features

  • RGB + CCT in one device: simultaneous color and dynamic white management with DT8 protocol (depending on model).
  • Superior light quality: richer chromaticity and more natural white vs. traditional RGBW or CCT systems.
  • Easy integration: two-wire DALI bus, free polarity.
  • Deep dimming <1%: smooth, flicker-free regulation even at low intensities.
  • PWM frequency: 250–500 Hz (entry), 1–4 kHz (mid), 8–16 kHz (high-end), also suitable for photo/video.
  • NFC programming: fast, customizable configuration for compatible drivers.
  • Energy efficiency: optimized consumption and longer LED lifetime.
  • Visual comfort & well-being: adaptive light that supports circadian rhythms and enhances residential and professional spaces.

Typical applications

  • Advanced circadian cycles: wellness clinics/spas, medical studios, offices.
  • Chromotherapy: relaxation rooms and wellness paths with warm, comforting tones.
  • Emotional showers: multisensory experiences with light/color, sounds and aromas.
  • Premium residential: high-end homes, living rooms and home theaters with chromatic scenes and adaptive white.
  • Hospitality: hotels, restaurants, lounge bars with multicolor and dynamic white scenes.
  • Retail: showrooms, displays and shop windows with advanced lighting effects.
  • Public & cultural spaces: museums, theaters, cinemas, galleries and artistic installations with scenic lighting.

Available types

  • DALI RGBWA 5CH (DT8): digital 5-channel regulation for RGB + tunable white, managed with a single DALI address.
