## Long description

Mean Well LCM-40TW is a tunable white constant-current LED driver with DALI-2 control, providing two independent constant-current outputs rated at 700 mA each. The driver is intended for adjustable white lighting where separate channels allow color temperature tuning and balanced current to LEDs. It supports digital lighting control using the DALI-2 protocol, enabling centralized dimming, scene setting and color temperature adjustment in commercial and architectural installations.
Advantages
The LCM-40TW offers two independently controlled channels at 700 mA, allowing precise control of tunable white fixtures. Built to work with DALI-2 systems, it enables integration into modern digital lighting networks for centralized control and automation. As a constant-current driver, it maintains stable LED current to support consistent lumen output and color stability during dimming and color temperature changes.
Suitable for
Commercial office lighting requiring tunable white and centralized control
Architectural lighting installations with adjustable color temperature
Retail and hospitality spaces where scene setting and dimming are needed
Retrofit projects replacing fixed white drivers with tunable white capability
Key specifications
Type: Tunable white constant-current LED driver
Control protocol: DALI-2 digital control
Outputs: Two independent constant-current channels
Output current: 700 mA per channel
Functionality: Dimming and color temperature tuning via DALI-2
