Bournemouth County Council was looking to significantly reduce both its energy and carbon levels as the current commitment of the £1.1 million bill going forward wasn’t sustainable for the authority. With the predicted increase in energy and the authorities’ growing lighting inventory, Bournemouth made the decision that 'Invest to Save' was the only viable option to keep the lights.
Various options were open to Bournemouth CC but a global, one for one replacement option, to replace existing stock was decided upon for ease of installation by the contractor. With 11535 units to replace the age and varying applications of the existing column stock needed to be considered, with this in mind the P852 LED luminaire was selected to replace their residential stock. The range of optics allowed coverage of the applications involved but the wide distribution was the best fit to cover most eventualities. Additionally, the low weight of the P852 at just 4.5kgs was a major deciding factor.
Flexibility and ease of installation for the contractor were key, they held both side entry and post top adaptors to improve the efficiency of mass installation on site, and all luminaires were pre-cabled during manufacture. The project had a 22-week manufacturing deadline to meet to enable the contractor to achieve the project installation date, CU Phosco Lighting and SSE worked very closely to ensure that this was achieved.
Bournemouth CC required the greenest possible solution overall for this project, saving both energy and carbon. The existing lanterns in Bournemouth were 70W Son (conventional magnetic gear) burning approx. 90 total circuits’ watts. Replacing these with the P852 LED luminaire demonstrated excellent energy & carbon reductions with a 72% energy saving. In addition to this CU Phosco Lighting was able to save 5.65 tonnes of cardboard by utilising reusable plastic crates to supply Bournemouth CC with all 11535 of their luminaires.
