DALI LED Controllers – RGBW 4CH

DALI RGBW: digital 4-channel regulation with dedicated white

Standard

DALI RGBW 4-channel controllers and drivers allow the combined management of red, green, blue, and white LEDs through the DALI/DALI2 protocol. In addition to RGB color scenarios, the dedicated white channel provides a true white light with greater luminous power, suitable for both decorative and functional lighting. Models are available with 12/24/36/48 V DC and 110/220 VAC input, with PWM outputs at constant voltage (CV) or constant current (100–1500 mA). Some DALI RGBW devices can be programmed via NFC and also operate in stand-alone mode, without a central controller.

System architecture

  • DALI RGBW devices: 4CH modules for managing R-G-B-W channels.
  • DALI/DALI2 LED drivers: CV/CC versions with PWM outputs for RGBW loads.
  • DALI wall panels: touch or slider controls for 502/503 flush-mounted boxes to adjust color, intensity, and dedicated white.
  • DALI Push Button Couplers: local management using 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.
  • Unique addressing: up to 64 devices per DALI line, with groups and scene assignment.
  • Multi-point/multi-zone topology: centralized or distributed management of multiple RGBW loads on the same bus.

Advanced features

  • RGBW color mixing: chromatic scenes with real, bright white.
  • Tunable white simulation: combining W with R/B yields warmer or cooler variants.
  • Easy integration: two-wire DALI bus (free polarity).
  • Modularity: simple expansion by adding drivers and devices.
  • Multi-point & multi-zone: independent or synchronized management of multiple areas.
  • Deep dimming <1%: smooth, stable, flicker-free regulation.
  • PWM frequency: 250–500 Hz (entry), 1–4 kHz (mid), 8–16 kHz (high-end), ideal for photo/video.
  • NFC programming: fast, customizable configuration.
  • DT6/DT8 support: devices available as DT6, DT8 or multi-function DT6+DT8.
  • Visual comfort & efficiency: adaptive scenes to enhance spaces while containing consumption.

Typical applications

  • Circadian cycles + chromotherapy: studios, clinics, spas and wellness.
  • Emotional showers: light/color sequences with sounds and scents.
  • Premium residential: living rooms, home theaters and living areas with multicolor scenes and functional white.
  • Hospitality: hotel rooms, lobbies, spas, lounge bars and restaurants with RGBW combinations.
  • Retail: showrooms, displays and promotional corners with dynamic effects.
  • Cultural spaces & events: museums, cinemas, galleries and artistic installations.

Available types

  • DALI RGBW 4CH: digital 4-channel regulation (RGB + dedicated white) through the DALI/DALI2 protocol.
