Feature Energy Efficient Lighting Lighting up the streets of Bristol
As part of Bristol City Council’s aim to reduce its carbon footprint, GE Lighting has upgraded the street lighting in the city to deliver an energy efficient, white light solution

standard E27/E40 bases and can be dimmed. Plus, with high reliability and sustained lumen output across a longer working life of 24,000 hours, they are cost effective. Furthermore, the lamps support electronic and elec- tromagnetic ballasts and are compati- ble with the major street light ballasts - enabling retro-fitting of existing HPS systems. GE Streetwise has approved ballasts with all major manufacturers. David Orchard, regional sales man- ager - south west at GE Lighting said, “Outdoor lighting has become a key consideration for many local authori- ties as they look to balance a duty of care to provide safe, secure streets against a backdrop of new legislation, a growing resistance to light nuisance and the need to reduce energy and carbon emissions. Lighting has had to evolve to become smarter, which is where the latest outdoor white light solutions come into play.”
ristol is the only city in the UK to have been shortlisted for the 2014 Green Capital Award, and as such has a strong environ- mental ethos. Upgrading its street- lights forms part of the city’s energy reduction scheme to generate substan- tial carbon savings. Much closer to daylight, white light offers advantages in the fact that pedestrians feel more secure in their environment and car driver reaction time (mescopic vision) is at least six times quicker.

Bristol Council has rolled-out the street lighting upgrade in two phases, the first of which saw the replacement of around 8,000 existing high pressure sodium lamps to GE’s CMH StreetWise ceramic metal halide lamps over a one year period. Phase two of the upgrade began in July 2012 and over the course of the next 12 to 18 months will see the replacement of a further 12,000 lamps in Bristol’s residential areas.
Greater savings and flexibility In addition, all the lamps have been replaced in conjunction with dimma- ble ballasts to allow for greater energy savings and to ensure the council has the flexibility to dim the new lamps (between 7.00pm and 6.00am) to an even lower output as and when required.
Robbie Park, principal lighting offi- cer for Bristol City Council, com- mented, “We are delighted with the street lighting upgrade to GE’s CMH StreetWise ceramic metal halide
lamps. Along with other energy reduc- tion projects financed with interest- free loans from Salix, the overall result is astounding and will not only make our streets safer but will enable Bristol to save 4.2 million kWh and £500,000 per year on our energy bills as well as a reduction in CO2
emissions.”
The CMH StreetWise ceramic metal halide lamp has been designed as an easy fit replacement for outdated tech- nologies. The lamps are fitted with
Councils looking to reduce energy and carbon emissions can now select from a range of options including LED and CMH outdoor solutions which are well suited for motorways, bridges, pedestrian areas and car parks. With virtually no ongoing maintenance expenses, both deliver significant operating cost benefits and therefore very attractive paybacks.

Group’s Inceptor integrated LED Downlights. Inceptor was specifically chosen as it provides a solu- tion to the issues surrounding restrictive ceiling voids - Inceptor can be fitted into a recess depth of just 60mm. Scolmore has also integrated its Flow Connectors
T
into the product, which make it quick and easy to install, as well as to remove and replace for the purpose of circuit testing - another positive when selecting the right products for the job. John Lawrence from Genlec Electrical Contractors
was responsible for the specification and installation of the products and commented, “We wanted to incorpo- rate LED downlights from both an energy efficiency and a low maintenance point of view and the Inceptor prod- uct met with these criteria and more. The light output is excellent and aesthetically the downlights work really well with the modern look that has been created. As well as a five year commercial warranty, the low mainte- nance factor will save costs in the long run.”

he redeveloped Pavilion at Lancashire Country Cricket Club (LCCC) has been fitted with Scolmore
Approximately 240 Inceptor downlights in a variety of finishes have been installed at the new look Pavilion, which was completed ahead of the Investec Ashes returning to Old Trafford in August and will provide state of the art facilities for LCCC members. It has retained its original red brick and sandstone facade and iconic tur- rets, but has undergone a modern overhaul and will be able to accommodate up to 700 guests, utilising eight suites and nine executive boxes.
