What Makes Our LED Retrofit Linear Fixtures Unique

 
 

Existing System Compatible

Designed to fit existing linear and trunking infrastructures, allowing direct replacement of traditional fluorescent linear lighting without changing overall layouts or power distribution.

 
 

Multi-Brand Compatibility

Designed to work with major trunking systems from Philips, Trilux, Zumtobel, Siteco, Ridi, and other mainstream brands, reducing replacement risks in retrofit projects.

 
 

Fast Project Installation

Enabling faster installation and fewer errors across large-scale projects, through tool-free mounting and plug-in connections, eliminates the need for complex on-site assembly.

Adaptable for Diverse Applications

Equipped with a variety of lighting modules to meet different lighting needs. Also, we have our own trunk rails to facilitate any applications that don't require pre-installed trunk rails.

 
 

High System Efficacy

High-efficiency LED technology combined with optimized optics delivers system efficacy up to 180 lm/W and low-glare performance (UGR < 19) for comfortable, energy-saving illumination.

 
 

Multi-Wire Compatibility

The trunk rail has 5/6/7/8/12 wires style that meets the different modules. The available lengths are 0.6 m, 12 m, 1.5 m, 2.4 m, and 3.0 m, which makes the trunk widely used on different applications.

Independent vs Linear Trunking System: How to Choose the Right One?

3

Independent Linear Lights

  • Single fixtures wired and installed separately.
  • Layouts are fixed after installation, requiring rewiring for changes.
  • Lighting quality may vary inconsistently across units,
    due to the installer's skill.
  • Full fixture replacement is often needed, causing higher disruption.
  • Best for small/simple spaces,
    and the performance degrades in large or continuous areas.
  • System vs. Fixture
  • Flexibility & Upgrade
  • Project Reliability
  • Maintenance
  • Large-Scale Use
4

LED Linear Trunking System

  • Integrated platform where power, control,
    and modules work together as one system
  • Layouts and functions can be modified,
    with modules swapped individually without rewiring.
  • Standardized components minimize wiring errors,
    ensuring predictable performance across all modules.
  • Use targeted lighting module replacement to avoid full-line downtime.
  • Supports continuous runs 100–200m,
    with uniform lighting in open spaces up to 2000 m²
