Photometric modelling and simulation for every application
Every project has its own constraints, standards and performance targets. Our engineers work alongside project designers and contractors to model, simulate and optimise lighting solutions using advanced photometric tools. From road and tunnel lighting to sports, industrial and urban applications, we deliver compliant, energy-efficient designs tailored to each site.
Why our design service matters
Photometric calculations optimised for visibility, uniformity and glare control, reducing accident risk and improving user experience across all applications.
Designs that minimise energy consumption, reduce CO2 emissions and limit light spill to protect nocturnal wildlife and biodiversity.
Full alignment with EN 13201, CIE 140, CIE 88, IES RP-8 and applicable regional standards, verified through independent software validation.
Reduced total cost of ownership through optimised product selection, energy performance and maintenance intervals.
Designs compatible with smart controls and connected lighting management systems for long-term adaptability.
Our lighting design process: from brief to installation
Lighting simulation with DIALux, Relux and Ulysse 4
Our engineers use industry-standard tools including DIALux and Relux, as well as Ulysse 4, Schreder's independently validated 4th-generation photometric calculation software.
Ulysse 4 includes dedicated modules for road lighting, tunnel lighting, sports lighting and obtrusive light assessment, alongside integrated TCO and CO2 calculations. This combination of tools ensures every design is precise, standards-compliant and optimised for long-term performance and sustainability.
Tailored to every environment
Certified expertise
Our lighting designs are developed in compliance with internationally recognised standards for road, tunnel and sports lighting.
Ulysse 4, our proprietary photometric calculation software, has been independently validated against these frameworks,
providing an additional layer of assurance on every project.

Lighting commissioning support: from design to operation
A lighting design delivers its full value only when correctly implemented on site. Our teams work alongside project designers and installation contractors to ensure every luminaire, driver and control system is installed, configured and verified against the original design intent. From initial commissioning checks to post-installation performance review, we provide continuity across the full project lifecycle, guaranteeing safety, regulatory compliance and long-term reliability.
Engineered reliability, tailored to your site
Every solar project begins with a precise, site-specific study. Using historical PVGIS data, we size panels, batteries and lighting profiles for the most critical period, when nights are longest and solar input is lowest. Components are engineered to balance energy production and consumption, with safety margins and mechanical designs adapted to real conditions, ensuring reliable, fully autonomous lighting year-round.

Frequently asked questions about our lighting design service
What is a lighting study and what does it include?
A lighting study is a technical document produced by our engineers that models the photometric performance of a proposed lighting installation. It typically includes illuminance and luminance calculations, uniformity ratios, glare indices, energy consumption estimates and compliance verification against the applicable standards (EN 13201, CIE 140, CIE 88, etc.).
Who is your lighting design service for?
Our service is designed for local authorities, project designers, engineers, contractors and facility managers responsible for specifying or commissioning outdoor lighting. Whether you are planning a new installation, retrofitting an existing network or upgrading to smart controls, our team can support your project from initial brief through to commissioning.
Which lighting simulation software do you use?
We work with DIALux and Relux, the two most widely used tools in the industry, as well as Ulysse 4, our own independently validated photometric calculation software with dedicated modules for roads, tunnels, sports and obtrusive light.
Can you design for a specific lighting standard or local regulation?
Yes. Our engineers are experienced in designing to EN 13201, CIE 140, CIE 88 and CIE 189, IES RP-8, AS/NZS 1158 and country-specific frameworks such as CETU in France. We can also adapt designs to project-specific or client-defined requirements.
How do you address light pollution and ecological impact in your designs?
Light pollution is a measurable design parameter, not an afterthought. We use obtrusive light calculations in line with CIE 150 guidelines to control spill light and sky glow. We also specify optics and spectral profiles that minimise disruption to nocturnal wildlife, and we integrate adaptive dimming profiles where smart controls are in place. Every design aims to deliver the required performance with the lowest possible ecological footprint.
Do you provide support beyond the design phase?
Yes. As a separate service, our commissioning support ensures the design is correctly implemented on site, with verification of installation, configuration and performance before handover.
