Cooper Lighting and Safety Delta Warehouse, London

Linergy luminaires from Cooper Lighting and Safety minimise energy consumption and ease maintenance at new Delta warehouse.


Cooper Lighting and Safety, a business unit of Cooper Safety, has supplied over 200 Linergy fluorescent luminaires incorporating passive infra-red (PIR) control for a new Delta Group warehouse in London.


The Delta Group is an environmentally


responsible supplier and has an ISO14001- certified Environmental Policy and Management System. So when Delta was looking at the lighting scheme for the new 180,000 square foot warehouse at its 6-acre London site, the overriding considerations were minimising energy consumption and reducing the company’s carbon footprint. Paul Brittain, Delta’s Head of Facilities, explained; “Because we operate our printing, storage and distribution facilities 24/7, our energy costs are inevitably huge, and we are always on the lookout for any sort of leverage we can get to reduce those costs.”


Hawk Systems then provided Delta with a choice of four designs based on fluorescent luminaires from different manufacturers. After a thorough evaluation

of the fittings, Delta selected the Linergy luminaire from Cooper Lighting and Safety. Providing a T5 fluorescent alternative to the discharge luminaires that are traditionally used for high-bay and low-bay lighting, Linergy offers benefits such as instant illumination, excellent colour rendering, white light appearance and emergency lighting capability. Linergy’s first-fix mounting plate and plug-and-socket connections helped seal the deal, as they make installation and maintenance very straightforward. Martin Cook, Project Manager at Hawk Systems, comments; “To achieve the necessary energy efficiency, we needed dimmable luminaires with individual PIRs in each fitting, so that only areas where people were working would be illuminated. All of the luminaires we considered were able to fulfil that requirement, but Cooper’s fitting was just so much easier to install and maintain.”


The Delta lighting scheme consists of 120 standard Linergy fittings and 105 emergency versions, which provide a 3-hour duration in the event of a mains


power failure. With an integral high-level PIR detector and photocell in each fitting, the Linergy-based scheme provides both occupancy detection and daylight- harvesting facilities. “The roof of the building incorporates numerous skylights,” commented Paul Brittain, “which means that on a really nice day there is a lot of natural light available, and so the Linergy fittings dim down to 10% of their output. Then, if the weather turns cloudy, the output increases in order to maintain the required average lighting level of 350 lux.” Paul Brittain added: “We are projecting electricity cost savings of around £30,000 a year compared with conventional discharge lighting, so the Linergy luminaire is certainly helping us to reduce our carbon footprint. It’s an impressive product and I’m sure we’ll be very happy with it.”
