Transport for London, Eastway Tunnel Lighting
Morson Praxis were appointed by Transport for London (TfL) to deliver a major lighting upgrade at the Eastway Tunnel, enhancing safety, energy efficiency, and long-term reliability on one of London’s busiest trunk roads.
Client Brief
A Smarter, More Efficient Lighting System
TfL required a modern lighting solution that would not only meet stringent safety and performance standards but also deliver significant energy savings and reduced maintenance costs.
Due to the tunnel’s limited headroom, all new infrastructure had to be installed within the existing cornice spaces, presenting a unique design and installation challenge.
Project Overview
Engineering Within Constraints
The Eastway Tunnel, a 290-metre dual-lane structure on the A12, previously operated with aging fluorescent and high-pressure sodium lighting. The control system relied on outdated photometer and contactor technology.
Morson Praxis were tasked with replacing this legacy setup with a modern, adaptive lighting system designed to improve visual conditions, reduce energy consumption, and provide precise control through intelligent automation.

Our Solution
Precision Lighting with Intelligent Control
Morson Praxis delivered a bespoke lighting and control solution, integrating advanced optical design with smart automation technology.
Key Features:
-
Customised TRT Verso luminaires, designed with asymmetric lens configurations – 75% directed at the roadway and 25% at the tunnel walls – ensuring optimal illumination without energy waste.
-
Cornice-mounted installation, utilising existing structure space to maintain headroom clearance.
-
Full feedback PLC-controlled eMaster system for precise, real-time lighting control.
-
DALI network integration, enabling dynamic dimming and responsive adjustment based on portal photometer readings.
-
Remote-mounted DALI drivers and dedicated tunnel enclosures for ease of maintenance and system reliability.
This fully dimmed system allows the lighting output to precisely match real-time luminance requirements, reducing unnecessary energy use and eliminating over-lighting.
Results
Brighter, Safer, and More Sustainable
The new lighting system has transformed the Eastway Tunnel, delivering:
-
Up to 25% energy savings through precise dimming control
-
Improved visibility and driver safety via optimised luminance balance
-
Enhanced reliability and maintainability through intelligent design and remote monitoring
-
Reduced operational costs and a future-proofed lighting infrastructure
