In historic city centres and architecturally sensitive areas, lighting is more than just infrastructure; it forms part of the urban identity. Replacing them with standard modern luminaires could compromise this identity. Our custom retrofit approach involves adapting the technology inside the luminaire while retaining its original housing and visual signature . Each project start with a detailed technical assessment of the existing installation, including its mechanical condition, optical configuration, thermal behaviour and mounting constraints. Based on this analysis, we design a bespoke retrofit solution that integrates modern LED engines, updated optics and connected control systems within the existing luminaire structure. In addition to project-specific retrofits, we offer standardised upgrade solutions for installed luminaires requiring improved connectivity or LED performance with our CIRCLE LED BASE and TECEO UPLINK solutions. These solutions are designed to minimise intervention and reduce downtime, while extending product life, without the need to replace the entire luminaire. Our retrofit solutions enable municipalities to: • accelerate energy transition targets by reducing energy consumption by up to 70%; • reduce embodied carbon by approximately 50% compared to full replacement; • preserve architectural coherence; • optimise total cost of ownership; • extend asset lifetime by 15–20 years or more.
This assessment system serves a dual purpose. Internally, it provides a structured, quantifiable framework for evaluating the eco- design performance of our products in line with ESPR requirements. Externally, it ensures transparency for our customers by explaining how our luminaires can be upgraded, maintained, refurbished and recycled to support their own sustainability and carbon reduction targets. This is also the basis on which we calculate our circular lighting objective. We calculate circular revenues exclusively on products that achieve a four-star rating under the Circle Light Label. This certification level means that a luminaire is designed for multiple life cycles through upgradeability, serviceability, standardisation, refurbishment and end-of-life recovery. This methodology ensures that our Circular KPI reflects genuine circular value creation rather than conventional replacement or spare-part sales. A Tailored Retrofit Approach for Heritage Projects Lighting technology continues to evolve rapidly. Although our luminaires are engineered to last 20 to 25 years or more, many installations completed over a decade ago no longer meet current expectations in terms of photometric performance, energy efficiency and connectivity. In most cases, however, the structural components, such as housings, brackets, mounting bases and decorative elements, remain in excellent condition. Rather than replacing these luminaires entirely, we advocate for the opportunity to upgrade the evolving internal technologies while preserving the enduring structure.
This approach fully embodies our circular economy strategy. By prioritising the reuse of durable components and limiting replacements to technological sub-assemblies, we can significantly reduce our material consumption, waste generation and transport-related emissions. Components removed during retrofitting are responsibly recycled, thereby contributing to a more closed material loop. Retrofitting is a strategic choice, not just a technical upgrade. It enables cities to modernise their lighting infrastructure, integrate smart technologies, and achieve significant energy savings, all while safeguarding the architectural heritage and urban identity that make public spaces unique.
