Toronto Subway Station Platform Custom LED Lighting (2026 Project)
Introduction — the On-site Problem
com), a Custom Indoor LED Lighting Manufacturer based in China, we were tasked with developing a complete lighting solution for a new Toronto subway station platform, slated for completion in 2026. The core challenge was illuminating a large, high-traffic, curved platform while adhering to stringent modern standards for passenger safety, visual comfort, energy efficiency, and long-term reliability.
The architectural design required continuous lines of light that followed the organic curve of the platform edge, a task impossible with off-the-shelf products. The lighting needed to provide high uniformity, excellent color rendering for CCTV clarity, and minimal glare (UGR<19) to ensure a safe and comfortable passenger experience.
What "custom" Meant on This Project — Capability Matrix
For this Toronto transit project, "custom" went far beyond simple fixture selection. It involved a deep collaboration with the project's architects and electrical engineers to manufacture luminaires that were precisely tailored to the station's unique geometry and performance requirements. This included creating over 25 unique fixture lengths to map the platform's curvature, integrating a specific micro-prismatic lens for glare control, and ensuring seamless compatibility with the station's DALI-2 network for control and diagnostics.

Engineering Solutions
Our engineering team addressed several distinct challenges to meet the project's ambitious design goals. The solutions were validated through extensive digital simulation and prototyping before full-scale production.
How Did We Engineer a Continuous Line of Light for a Curved Platform?
The primary architectural feature was a long, sweeping curve along the platform edge that required uninterrupted illumination. Our solution was to fabricate a series of straight linear LED profiles in precise, variable lengths.
5m, each cut to a tolerance of +/- 1mm. These segments were designed with seamless connectors, allowing them to be installed end-to-end to form a visually continuous ribbon of light that perfectly traced the architectural curve without any dark spots or visible gaps.
What Was the Strategy to Achieve UGR<19 and High Uniformity?
Passenger comfort and safety were paramount. To combat glare from the continuous overhead light source, we integrated a specialized micro-prismatic diffuser into the luminaire design.
This optic, combined with an asymmetric beam shape, directed light downwards onto the platform floor and away from the direct line of sight of waiting passengers. We used DIALux simulation software extensively to model the entire platform.
- with an average illuminance of 200 lux, eliminating dangerous shadows.
How Were Emergency Lighting and System Diagnostics Integrated?
Reliability and maintenance efficiency are critical in a 24/7 transit environment. We specified Tridonic DALI-2 drivers that support integrated emergency lighting functionality.
In the event of a power outage, designated fixtures automatically switch to battery backup power, providing code-compliant egress illumination. Furthermore, the DALI-2 system enables the station's Building Management System (BMS) to receive real-time status updates from every single luminaire.
This diagnostic capability reports driver failures or lumen depreciation, allowing maintenance crews to perform proactive, targeted repairs instead of reactive, station-wide inspections.
Project Results — Design Targets
As this project is scheduled for 2026 commissioning, all results are based on simulation data and specified design targets. The lighting solution is engineered to meet or exceed all performance criteria defined by the transit authority and their consulting engineers.
- Illuminance & Uniformity: The DIALux simulations confirm an average horizontal illuminance of 200 lux on the platform surface with a uniformity ratio (Emin/Eavg) greater than 0.4.
- Visual Comfort: The specified optical assembly achieves a calculated UGR of <19 across all primary viewing angles.
- Longevity & Maintenance: The system is designed for an L90B10 lifetime of over 50,000 hours, drastically reducing the projected maintenance frequency compared to legacy fluorescent systems.
- Energy Efficiency: The solution is projected to achieve a system efficacy exceeding 120 lm/W, contributing significantly to the station's overall energy efficiency goals.
Photometric Files & Compliance (IES / LDT / DIALux / CE / RoHS)
Full technical documentation was a key deliverable. For each custom luminaire variant, XHLWX produced comprehensive IES and LDT photometric files.
These files were provided to the project's electrical engineering team, who imported them into DIALux Evo to conduct the final, independent lighting simulation and verification for the entire facility. All components and finished luminaires are certified to meet cULus (for Canadian safety standards), CE, and RoHS requirements, ensuring full compliance for a public infrastructure project.
Frequently Asked Questions
Q: What Correlated Color Temperature (CCT) Was Specified for the Station Platforms?
The design specification required a neutral 4000K CCT. This color temperature provides excellent visual clarity and a clean, modern aesthetic without feeling too cold or sterile. It was selected to align with IES RP-7 recommendations for transit environments, ensuring high visibility for passengers and staff.
Q: How Are the LED Fixtures Customized for Length?
Our aluminum extrusions are cut to precise lengths, down to the millimeter, at our factory based on the project's architectural drawings. For this project, we produced over 25 different lengths ranging from 0.5m to 2.5m, allowing the fixtures to follow the platform's curvature seamlessly.
Q: Are the Lighting Controls Compatible with Other Building Systems?
Yes, the DALI-2 control system is an open protocol standard (IEC 62386) designed for interoperability. It can be integrated with the main Building Management System (BMS) via a gateway, allowing centralized monitoring of energy consumption, scheduling, and fault reporting for the entire station.
Q: What Is the Expected Lifetime of the Installed Luminaires?
The luminaires are engineered for a long service life, with a design target of L90B10 at 50,000 hours. This means that after 50,000 hours of operation, at least 90% of the fixtures will still provide 90% of their initial light output, minimizing maintenance cycles in the busy transit environment.
