LED CCT Dual White Controller 2700K-6500K

LED CCT Dual White Controller – Stepless 2700K-6500K

The CCT (Correlated Color Temperature) dual white LED controller provides stepless, independent control of warm white and cool white LED channels for precise color temperature adjustment from 2700K (ultra-warm) to 6500K (daylight cool). By simultaneously adjusting the relative brightness of warm and cool white LED strips, this controller achieves smooth, perceptually linear color temperature transitions across the full tunable white spectrum.

The controller uses a 2-channel independent PWM architecture with each channel delivering 5A for a combined 10A total output. The 16-bit PWM resolution ensures smooth transitions at every brightness level, with no visible stepping during color temperature changes. A dedicated brightness channel allows independent dimming from 1-100% without shifting the selected color temperature, maintaining consistent light quality at any intensity.

Three operating modes are available: manual mode (direct knob adjustment of CCT and brightness), preset mode (4 recallable user-defined CCT/brightness combinations), and automatic circadian mode that gradually shifts from 6500K at midday to 2700K at evening over a user-configurable 24-hour cycle. The OLED display clearly indicates current CCT, brightness percentage, and active mode.

Specifications

Applications include human-centric office lighting that follows circadian rhythms, healthcare patient room lighting, photography and video studio lighting, retail cosmetics and fashion display where color-accurate illumination is critical, and high-end residential lighting for living spaces where tunable white ambiance enhances comfort and wellbeing throughout the day.
