Make linear lighting fixtures smarter
The new LF Series Linear Intelligent Driver from LTECH brings smart control and energy efficiency to modern linear lighting. Ideal for airports, offices, shopping malls, and commercial spaces, it offers flexible installation options both inside or outside luminaires and supports multiple intelligent dimming standards for seamless integration.
Available in 40W, 60W, and 80W models, the LF Series meets the Zhaga interface protocol and supports both DALI-2 and 0–10V dimming systems, ensuring full compatibility with international standards.
Two major dimming protocols: DALI and 0–10V
The LF Series supports DALI-2 DT6/DT8, Push DIM, and 0–10V/1–10V/PWM/RX interfaces, allowing precise brightness and color temperature adjustment.
Its NFC near-field programming enables one-click configuration through a smartphone, giving lighting designers full control over parameters like DALI address, output current, and dimming curves.
This flexibility makes it suitable for diverse applications across smart offices, architectural lighting, and professional retail environments.
Independent built-in and external designs
The LF Series offers built-in and external configurations to fit a wide range of installation needs.
It can be mounted inside luminaires, on ceilings, or in light slots, meeting Class I, II, and III indoor safety requirements.
Following Zhaga Book 13, 14, and 24 standards, the unified design allows for easy replacement, upgrade, and maintenance of components.
Intelligent programming and precision control
With NFC programming, users can edit lighting parameters directly from their mobile device. The driver supports the LTECH mobile app, compatible with major smart home and lighting brands such as Huawei, ORVIBO, Aqara, and Yeelight.
Parameters like current output, DALI address grouping, dimming type, and fade timing can all be fine-tuned within seconds, enabling precision lighting management.
Advanced control performance
One driver can manage up to two lights, supporting independent or synchronized control.
It also includes advanced features such as:
- Corridor Light Function with motion sensing and automatic dimming
- Emergency Lighting Mode for consistent brightness during power failure
- CLO (Constant Lumen Output) to maintain light consistency and extend fixture lifespan
L-Data intelligent feedback system
The LF Series integrates L-Data (DALI Part 251/252/253) for real-time energy and diagnostic monitoring.
It provides accurate energy consumption analysis, fault detection, and system health reports, helping building managers achieve smarter, more efficient lighting operations.
T-PWM® Super Deep Dimming
Featuring LTECH’s industry-leading T-PWM® Super Deep Dimming Technology, the LF Series achieves flicker-free dimming down to 0.01% (1:10,000 level).
This ensures smooth, soft illumination suitable for both workplace comfort and professional environments such as photography, film, and architecture.
Energy-efficient and eco-friendly
Complying with the EU ErP energy efficiency standard, the LF Series operates with standby power consumption below 0.5W.
Its constant power design maintains stable brightness across color temperatures, reducing energy waste and ensuring consistent light output.
International safety and certification
Built to meet global engineering requirements, the LF Series holds over 10 international certifications, including CE, TUV, RoHS, EAC, ErP, EL, and DALI-2.
Its reliability and quality make it ideal for projects requiring long-term stability and compliance with international safety standards.
