LIGHTING FEATURE Making the world a brighter place
Philips Lighting talk to Electrical Engineering magazine about two recent LED installations in the UK - one in two animal feed stores at Royal Portbury Dock, and one at London’s exhibition and conference venue, the ExCeL
he installation at Royal Portbury Dock, which has seen the lighting upgraded to Philips LED CoreLine highbay fittings in two animal feed stores, has resulted in annual energy cost savings of over £27,000 with an estimated return on investment within one and a half years. The dock, which is part of the Port of Bristol and is operated by The Bristol Port Company, was opened in 1977 and is situated near the village of Portbury on the southern side of the mouth of the Avon. The port handles a wide range of goods including motor vehicles and bulk cargoes. With a strong commitment to sustainability and minimising its environmental impact, the Bristol Port Company took the opportunity to upgrade the lighting in its animal feed stores when it became necessary to remove busbars. To that end, Ashfield Electrical Services (SW) was asked to propose a solution that would reduce energy consumption while also improving the lighting. Ashfield’s John White recalled, “It was clear that LED lighting would provide the best solution so we consulted with Bristol-based lighting specialists Lighting Services to explore the options available. When installing LED lighting our first choice is always Philips because of the quality and reliability. For Royal Portbury Dock we proposed using Philips LED CoreLine highbay fittings and took samples to the client for their approval. They were also very pleased with the cost of ownership projections and the potential energy and carbon savings.” The 220m long stores are configured with a broad roadway, capable of accommodating three lorries side-by-side, running
T
through the centre of the store with bulk handling bays on either side. They were previously lit using 250W high pressure sodium (SON) high bay fittings (100 in total), sited either side of the roadways. When gear losses were taken into account, this amounted to an installed electrical load of 27,500W. These have now been replaced on a point-for-point basis with 108W highbay LED fittings, resulting in a 61% reduction in installed electrical load, with an increase
in lighting levels of around 20%.
Because of the dusty atmosphere the
highbay fittings are
IP65 rated. In addition to the savings in energy consumption and carbon
emissions The Bristol Port Company will also benefit from reduced maintenance costs as the new fittings have a projected lamp life of 50,000 hours, compared to 12,000 hours for the previous SON lamps. White concluded,
“With higher light levels and a whiter light, the new fittings have created a much brighter environment which has received positive feedback from many of the people working in the stores.”

Also reducing its carbon emissions and energy consumption is the ExCel in London after the conference and exhibition
venue upgraded its lighting to Philips GentleSpace highbay LED luminaires. Situated at the heart of London’s Royal Docks, ExCeL London has 100,000m2
of
exhibition and conference space and has 46 sub-dividable halls and hosts a wide

range of events that differ considerably in size and lighting requirements. “With the original system we had very
limited control of the lighting, so if exhibitors wanted small areas of lighting switched off this could only be done by disconnecting individual luminaires manually,” recalled ExCeL’s operations director Brian Cole. “Given that the luminaires are mounted at a height of ten metres, this was time consuming and expensive. Frequent lamp replacement was a further burden on our maintenance resources. “The new luminaires are individually addressable so we now have the flexibility to address clients’ lighting requirements very precisely, while the improved lighting greatly enhances the experience for visitors and exhibitors alike,” he added. In addition, ExCeL London is certified to both the ISO 14001 environmental standard and ISO 20121, which sets sustainability management standards in the events industry. Upgrading the lighting therefore, has added to the already huge savings in carbon emissions that have been achieved in recent years. The original lighting, much of which
was 13 years old, consisted of 2,045 high bay luminaires using 400W high pressure sodium lamps. In a turnkey project delivered by Philips and installers Elite Renewables, these have been replaced with 2,145 GentleSpace 138W LED
luminaires, reducing the installed
electrical load by over 60%. Combined energy and maintenance
savings are expected to
provide a return on investment within three years. Cole concluded, “The new lighting is a
valuable sales tool and a significant point of difference for ExCeL, compared to other venues, as it enhances exhibitors’ displays and means they no longer have to install additional lighting on their stands to supplement poor ambient lighting.”
