Alstom are a French multinational manufacturer holding interests in electricity generation and transmission, as well as rail transport and infrastructure. Alstom manufacture and maintain rail and tram networks all over Europe, including the Eurostar and the TGV; here in the UK the most recognisable of these are the iconic tilting Virgin Pendolino and Voyager fleets.
Steon Lighting were approached by Quartzelec Ltd. to collaborate in providing Alstom with more sustainable and maintenance free lighting schemes for 7 of the 12 pit lanes at their Manchester facilities.
The existing lighting scheme in EDT lanes 1 and 2 featured 58W T8 linear surface mounted IP65 luminaires. Similarly, in lanes 2-4, 58W T8 fluorescent lamps were used however they were recessed into the pit lane walls. T8 lamps are now considered dated technology which has since been superseded by more efficient and reliable alternatives. The typical lamps life is approximately 10,000 hours, therefore with so many lamps of this type being on 24 hours a day, they require a considerable amount of maintenance. The installation in lanes 11 and 12 featured elliptical high intensity discharge mercury lamps (MBFs) which operated at 80W.
Steon Lighting recommended a transition from fluorescent to LED. They provided alternative 34W Alley Pack Cloud LED in EDT lanes 1 and 2.
Making use of high quality Osram LEDs, this product is more efficient and reliable, with a lamp life exceeding 50,000 hours. The product is capable of being installed into pre-existing recesses in the pit lane walls, making them less obtrusive.
The fluorescent 58W light sources in lanes 2-4 were replaced by high quality 36W LED printed circuit boards. In lanes 11 and 12, the existing lamps were replaced by 190 bespoke gear trays featuring high quality 40W LED printed circuit boards.
Following the upgrade the lux levels within the pit lanes had enhanced, despite their being the same number of luminaires in application. On average, the lighting operating cost was reduced by 41%.
Additional energy savings were achieved as all the lighting solutions incorporated intelligent lighting controls. Furthermore, almost half of the supplied luminaires feature integral self-contained 3-hour emergency functionality.
The combination of luminaire efficiency and lighting controls has resulted in considerable energy savings in each of the upgraded pits, based activity and usage projections Alstom should reap the benefits of energy savings exceeding 75%. Further savings are attributable to enhanced reliability which results in reduced maintenance requirements.
