Luminaires at Brent Cross Shopping Centre are remanufactured

Brent Cross Shopping Centrem lighting

The luminaires at Brent Cross Shopping Centre in north London have been remanufactured rather than replaced.

Trojan Lighting retrofitting the lights, upgrading them from fluorescent to LED and adding wireless controls in the process.

The project, commissioned by Hammerson, encompassed front-of-house and back-of-house areas, car parks, external entrances, and the entire network of shopping malls, one of the UK’s most popular retail destinations with an annual footfall of 12.5 million shoppers.

A key element of the upgrade involved remanufacturing the centre’s outdated fluorescent lighting troughs, a process that significantly enhanced energy efficiency and lighting quality.

Trojan collaborated closely with GA Harpers, facility managers, and electrical engineers to develop a bespoke solution.

This included site visits to measure and remove existing troughs, designing new gear trays for optimal light distribution, and manufacturing 282 custom 1.2m troughs.

The retrofit approach preserved the architectural integrity of the site while meeting modern lighting standards.

The installation featured 600 advanced luminaires, including Trojan’s Jarrow, Grimrod, and Dorchester models. These fittings, designed for durability and performance, offer lifespans of up to 100,000 hours, IP66 and IK10 ratings for external resilience, and an efficacy of 152lm/W.

Using Tridonic boards and drivers, the system ensures reliability, energy efficiency, and compatibility with control technologies.

Central to the upgrade was the integration of MyMesh-enabled lighting, transforming Brent Cross into a smart building network. This innovative wireless system supports automated emergency lighting testing, energy monitoring, and adaptive lighting scenes tailored to enhance the shopping experience.

The self-organising MyMesh network also facilitates integration with sensors and controls, providing facility managers with real-time insights into energy usage, maintenance needs, and fault detection.

Trojan Lighting estimates that there will be a 71 per cent reduction in energy ue, equivalent to 51 tonnes of CO2 savings in the first year alone.

The project’s return on investment is estimated at 1.67 years.

The company says that the upgrade has not only improved the lighting quality but has also empowered Brent Cross’s management with the tools to optimise building performance.
