    Cost Calculator The pressures on reducing energy, maintenance costs and operating costs will continue to increase so that climate change objectives can be met. Understanding the total cost of an installation over its whole life is becoming increasingly important as budgets become tighter and long term planning is required. The Total Cost of Ownership Tool from WRTL allows you to compare the complete cost of alternate lighting solutions alongside Stela so that you are able to make informed decisions on long term sustainability.

Technical advice and support

Our unique, single source approach equips us to provide you with fully informed technical support at any stage of your road tunnel lighting project. With our wide experience and expertise, we are able to support you in detail on all types of lighting and control system applications, whether for new, refurbishment or retrofit projects.

Retrofit and refurbishment

Where you require an existing installation to be replaced, refurbished or upgraded, our engineering team will provide you with a comprehensive survey with recommendations of all necessary work to bring your road tunnel lighting up to current standards.

Field engineering team

The i-TunneL® field engineering team is always available to provide you with on-site support and assessments, wherever your location.

Standards interpretation

Our international experience and extensive technical contacts allows us to advise you on the exact requirements and interpretation of different national and international standards for lighting, electrical control and safety aspects.

Lighting scheme design

Whether it be a new design, refurbishment or a change to lighting requirements, we can provide a detailed design using in-house tunnel lighting software, conveyed on a clear 2D layout drawing to detail intimation with the control system. This allows us to meet the needs of your tunnel precisely.

Specification preparation and approval

We offer you a full specification that will prepare the complete road tunnel lighting control installation and take it through all the approvals stages with your clients and third parties.

Manufacturing

Our high performance, durable road tunnel luminaires are manufactured to our precise specifications by our group companies in some of the most advanced facilities in Europe. Similarly, our control systems designs are manufactured to meet the most arduous road tunnel conditions while delivering utmost reliability and efficiency.

Bespoke software

From lighting scheme design to luminaire and installation control, we have developed our software systems so that we can meet your needs and specifications exactly.

Commissioning and training

As part of our service to you, we naturally include the road tunnel lighting system commissioning to bring it into service, and full operational and maintenance training of operating personnel.

Lighting Measurement

In addition, for an existing installation, our engineers can measure the lighting performance of your tunnel installation for all stages of lighting within all zones, whether it is for compliance with your maintenance regime, or for general lighting evaluation.

Site survey and reports

Our highly experienced site engineers will undertake a complete survey of your site and all lighting parameters including dimensions and optimum control equipment positioning. Their report is a fundamental part of the overall scheme design.

Post commissioning services

We offer a number of on-going services and maintenance, including luminaire cleaning and bulk lamp replacement, operational training of new staff and system assessments and upgrades.
