Product Details

High-Performance DALI Constant Current CCT Dimmable LED Driver for Professional Lighting

Introduce intelligence, efficiency, and flawless control to your lighting projects with Starwell advanced DALI Constant Current CCT Dimming Led Driver. Engineered for professional architects, lighting designers, and system integrators, this driver is the cornerstone for creating dynamic, energy-efficient, and reliable lighting systems in commercial, retail, hospitality, and architectural applications.

This driver delivers pure, stable constant current, specifically optimized for DT8 LED modules. It ensures consistent, flicker-free illumination, protecting your LED investment and guaranteeing visual comfort. With a universal 100-277VAC wide input range, it is perfect for global projects and simplifies inventory for both new installations and retrofits.


Unlock unparalleled flexibility and control. Choose the driver that bridges intelligent protocol and practical simplicity.

At the heart of its performance is high energy efficiency up to 86%, significantly reducing operational costs and heat generation. The integrated active PFC (Power Factor Correction) ensures compliance with harmonic standards and maximizes power quality from the grid. Built for unwavering reliability, it features robust protections against short circuit, over current, and over temperature (SCP/OCP/OTP). Its compact, full-protection plastic housing ensures safe and easy installation, while the IP20 rating and free air convection cooling make it ideal for a wide range of indoor installations.

Our driver excels in control flexibility. It seamlessly integrates into any DALI-2 ecosystem (IEC 62386 protocol), enabling advanced dimming, grouping, and scene setting for smart building management. For simpler setups, the integrated PUSH dimming function offers a convenient manual control option. Choose between logarithmic (default) for perfect human-centric dimming or linear curves to suit specific application needs. This combination ensures strong compatibility and supremely smooth, flicker-free dimming from 100% down to the lowest levels.

Application Scenarios

DALI Constant Current CCT Dimming Led Driver is suitable for high-end architectural, commercial, and hospitality projects, it empowers precise adjustment of light color temperature and intensity from a single driver.
