Stagecoach Supertram has undertaken a project to replace all high intensity sodium lamps in the city over a period of five months.
The network’s new 50-stop LED replacements are brighter and it’s estimated that over 800,000 kWh of energy will be saved each year by using 80% less energy.
The cost of the project was not disclosed.
But Mark Tomkins of Stagecoach Supertram, said the investment should pay for itself within 18 months due to massive energy savings and a greatly reduced maintenance bill.
A selection of test areas were chosen for the lights and Supertram bosses received feedback from drivers, passengers and residents who live near the stops.
The majority of stops, which have four to six tower lights, have been replaced and only two stops remain on the network that need upgrading.
Supplied by Guildford Signify, the upgrade is a switch from energy-intensive SON-T lamps to the new Philips TrueForce Core LED Road 40W lamps, which promise “improved white light quality in areas in contact with the customer for increased safety and improved color rendering for better visibility.’
Mark Tomkins, Electrical Infrastructure Coordinator at Stagecoach Supertram, said: “For a long time we have been looking for the best replacement that physically fits into existing luminaires, eliminating the need to replace them. We also had to make sure that the new bulbs met all of our objectives for increased safety, better visibility and respect for the environment.
“Philips’ LED lighting solutions provide better color rendition, better CCTV visibility, increased passenger and staff safety and better visibility at tram stops.
“The energy savings are impressive compared to conventional light sources and sustainable products.
“With the instant re-strike of the new LED lights, it removes the waiting period of HID cooling in the event of a power failure.
Simon Greenwood, Sales Director for Trade and Specifications at Signify, added: “Our LED solution for the tram network will encourage travelers to travel on the line worry-free through improved visibility and safety. The positive impact on the environment is another huge benefit.
