A University of Oxford analysis of 50 lighting projects reveals that circular strategies can significantly reduce costs and energy usage. Businesses are increasingly opting for component upgrades over full system replacements to minimize operational disruption and capital expenditure.
Why it matters
Full lighting system replacements often incur unnecessary costs and downtime when existing infrastructure remains functional. Adopting circular practices allows operators to extend asset life while achieving significant energy savings, as evidenced by large-scale projects.
An analysis of 50 lighting projects shows 37 reported capital or maintenance benefits, while 36 projects achieved a median energy reduction of 59.5%. In one instance, the Dublin Port Tunnel saved €3 million in capital costs by upgrading 1,800 existing light points rather than replacing them.
The players
University of Oxford
A global academic institution that conducts research on infrastructure and sustainability strategy.
Signify
A large-scale lighting company that designs systems, services, and software for commercial and industrial markets.
The details
Circular lighting involves assessing infrastructure to upgrade specific components rather than performing a full system overhaul. The Signify Circle program facilitates this by utilizing spare parts, upgrade kits, and Light-as-a-Service models to preserve asset value. These methods allow businesses to avoid the construction, disposal, and facility downtime associated with traditional replacement cycles.

Market Landscape
The analysis follows a shift toward resource efficiency, aligning with circularity principles within the European Green Deal by prioritizing asset retention over disposal. It serves as empirical evidence for the business viability of circular models within this broader policy framework.
Operators should evaluate existing lighting infrastructure for upgrade potential before committing to a full system replacement. Analyze potential capital expenditure savings against the projected energy reduction targets of 59.5% to determine the payback period for component upgrades.
The takeaway
Circular lighting strategies effectively bridge the gap between sustainability goals and capital preservation. Operators should audit current lighting assets and consult with vendors about upgrade kits or service-based models as alternatives to total system replacement.
